Jean-Paul Chaput cfcd4b7115 Do not for materialization in RoutingPad::setExternalComponent().
* Bug: In RoutingPad::setExternalComponent(), we where always forcing
    the materialization of the RoutingPad (QuadTree insertion). Now
    respect the Go::enableAutoMaterialization() state.
      Forcing the materialization is equivalent to having an
    UpdateSession. So when creating large amount of RoutingPads it did
    result in huge slow down, like in HFNS algorithms.
      With this modification we go down from 6h+ to 4m for the ls180.

Jean-Paul Chaput 11390867f1 A more compact string representation for Hurricane::Path. 2021-03-15 23:45:33 +01:00
Jean-Paul Chaput a6492f6edc Allow Hurricane::Query to stop on master cells with designated flags.
* New: In Query & QueryStack, add a new stop criterion "stopCellFlags"
    based on the flags of the instances master cell. The instance will
    still be processed, but not it's childs. Typically used to stop
    exploring on "AbstractedSupply" cells.
      Exported in the Python interface.
* New: In Cell::Flags, new value "AbstractedSupply" to mark Cells from
    which an abstract has been built for supplies & blockages. But *not*
    for common nets. Helps reduce the recursion through the hierarchy
    when building supply line in FlattenPower.
      Export setter/getter in the Python interface.
* New: In Instance, add a "PruneMaster" filter to stop hierarchical
    exploration on instances which master cells have at least one of
    the given flags set.
* Change: In NetExternalcomponents::isInternal(), use "const Component*"
    instead of "Component*".
* Bug: In Cell::Flags, the NoFlags must be *zero*, not *one*! And we
    can reclaim that bit for future use.
* Cleanup: In Hurricane::Cell, remove changeQuadTree() related methods.
    Fusing various Cell's QuadTree is not a viable idea.
* Cleanup: In Hurricane::Instance, remove no longer used "_flags"
    attributes.

Jean-Paul Chaput 250ef29674 Fix the smart truncate display in DbU::getValueString(). 2021-01-13 19:04:13 +01:00
Jean-Paul Chaput 3b5a0f5bd2 Again, bug fix in the Inspector support, on getSlot<> template.
The policy about how to create slots was not completly clear.
Now, only add *pointers* or *references* to class attributes,
never do a "copy by value". Reflect that change in SlotTemplate<>
various partial specializations.
  Hammer in your head that in C++ functions templates do not allow
for partial specialization. So write only *one* template for
::getSlot<>() (refdefinition simply got ignoreds, at least with gcc).

* Bug: In Slot, only one template for getSlot<> (see above).
    Adjust SlotTemplates<> to provides partial specialization only for:
    * "const Data&".
    * "Data*".
    * "const Data*".
    * "Data* const"
    * "Record*".
* Bug: In Instance::_getRecord(), suppress slot based on transient
    values "XCenter" & "YCenter".
* Bug: In CRL::ToolEngine::_getRecord(), suppress slot "Name" based
    on a transient value.
* Change: In ::getRecord(std::list<Elementt>*) (and variant), pass
    all elements to ::getSlot() as (const Element*).

Jean-Paul Chaput be5483a0ad Do not skip thin (elongated) QuadTree leaves. 2020-12-04 12:14:08 +01:00
Jean-Paul Chaput 642579b444 More fix for the slow display in CellViewer.
* Change: In Hurricane::QuadTree_GosUnder::Locator::progress(), directly
    prune the elements which sizes are under the threshold. This allows
    the too small Instances to be directly skipped. This was the key
    point slowing the walktrough. We were systematically going through
    all the instances (that is consistent with the perf traces).
* Change: In Hurricane::Cell_OccurrencesUnder, add a threshold parameter
    to pass on the QuadTree (through getInstancesUnder()).
      Needed for the CellWidget selection to have the same problem as
    the display itself (select only what is displayed).
* New: In Hurricane::CellView, add two new parameters:
    1. "viewer.minimumSize" set the original size of the window, in pixels.
       (doubled for HiDPI).
    2. "viewer.pixelThreshold", the size, in pixels, under which
       components/instances will not be displayeds.
* New: In CRL/etc/cmos.misc.py, added parameters "viewer.minimumSize"
    and "viewer.pixelsThreshold".
2020-12-02 20:02:55 +01:00
Jean-Paul Chaput 7feb39d056 Separate size check for Hurricane::Contact & Hurricane::Pin.
* Change: In Hurricane::Contact, as it is the base class of Pin, a
    width *or* height can rightfully be null (according to the
    Pin orientation).
      Put the check in a Contact::_postCheck() function.
* Change: In Hurricane::Contact, replace all the "const DbU::Unit&"
    parameters by simply "DbU::Unit".
* Change: In Hurricane::Pin, add a dedicated _postCheck() function.
2020-12-02 19:12:27 +01:00
Jean-Paul Chaput e08bc9a407 Check contacts for minimal size in real mode.
* Change: In Hurricane::Contact::Contact(), check width & hieight of
    the contact against the minimal size, if below, bellow a warning
    and increase the dimension.
      May too paranoid when used on turn in same metal (no cut).
2020-11-25 21:51:43 +01:00
Jean-Paul Chaput f5ee37d2e6 Manage minimum area for VIAs in the P&R.
* New: In Hurricane::Layer, add support for a minimal area (given in
    microns). Exported in the Python interface.
* New: In Anabatic::AutoSegment::bloatStackedStrap(), method to
    enlarge too small vertically stacked VIAs. For now just create
    a square ensuring the minimal area. Potentially cause DRC error in
    some cases so needs to be refined.
* New: In Anabatic::_gutAnabatic(), check for too little stacked VIAs
    and display a report.

Jean-Paul Chaput c6e5583233 Documentation cleanup & rebuild.
* Change: In documentation/build.py, more PEP8 & Python 3 future compliance.
    Correct copy of the tools HTML docs on my laptop, to have a full
    offline copy of the doc.
* New: In documentation/contents/pages/check-toolkit, duplicate the doc
    from alliance-check-toolkit README. Seems it has been inadvertently
    removed at some point (?). Have to be careful to maintain in synch
    with the toolkit.
* Change: <tool>/doc/*/SoC.css, use Roboto fonts when availables.
* Update: Commit the whole pre-generated docs (Doxygen, Pelican).

Jean-Paul Chaput 3993f948b7 Change the way the grid is drawn in CellWidget.
* Change: In CellWidget::drawGrid(), for the "super-grid", now use
    lines instead of small crosses. The super-grid is set to 10 point
    of the snap grid in all cases (symbolic, real, foundry grid).
* New: Export CellWidget::setDbuMode() to CellViewer, and into it's
    Python wrapper.
* Bug: In CellWidget::setCell(), keep the dbuMode when loading a new
    cell instead of reverting to default.
2020-10-25 12:05:54 +01:00
Jean-Paul Chaput 79f3350eba More explicit error message in Cell.getNet() Python wrapper. 2020-10-14 14:58:32 +02:00
Jean-Paul Chaput 8f0a8e5a3a Added support for loading user defined global routing in Anabatic.
* New: In Hurricane::NetRoutingProperty, add and change the meaning
    of the following flags:
      - ManualGlobalRoute : now means that a global routing *trunk*
        is present, made of "gmetalh", "gmetalv" & "gcontact".
      - Manualdetailroute : added, get the former meaning of
        ManualGlobalRoute, that is, the detailed routing is
	already present for this net, but can be changed by the
	detailed router. Implies that it respect the Terminal,
	HTee & VTee structuration.
* New: Add Anabatic::Diskstra::loadFixedGlobal(), to account
    a manually global net into the edges capacities.
* New: In Anabatic::Edges::ripup(), exclude manually global routed
    segments from the ripup. Change the segment sorting function
    so that thoses segments are put in head of list (considered
    as "smaller").
* Change: In AnabaticEngine::setupPreRouteds(), now detect manual
    global routed and manual detail routed signals, and tag them
    accordingly.
* New: In AnabaticEngine::Configuration & Session, add proxies
    for the global routing layers ("gmetalh", "gmetalv", "gcontact").
* New: In Anabatic::Constants, add flags for global fixed and
    detail routed nets.
* Change: In KatanaEngine::updateEstimateDensity(), now use int64_t
    for flute coordinates.
* New: Add CRL::RoutingGauge::hasLayer(), to know if a layer is
    managed by the gauge (comparison by mask).

Jean-Paul Chaput e53113ebb1 Just some manic code beatification. 2020-09-14 11:15:15 +02:00
Jean-Paul Chaput f00b8cd667 Allow RoutingPad::getPlugOccurrence() to build upon a Pin.
* Change: In Hurricane::RoutingPad::getPlugOccurrence(), it was
    forbidden to rebuild the Occurrence over anything other than
    Plug. But as we now also uses Pins, it becomes useful to
    rebuild the Occurrence on a Pin. The name of the function
    stays, even if its less meaningful now.
2020-09-11 12:56:35 +02:00
Jean-Paul Chaput 3e6d5622e8 Improvement on Python interface of Occurrence, Point & CellViewer.
* Bug: In Isobar::PyOccurrence, use "compare by value" instead of
    "compare by pointer" for the Python comparison function. So we
    really can compare identical Occurrences.
* New: In Isobar::PyPoint, export the "manhattanDistance()" function.
* New: In Isobal::PyCellViewer, add the following funtions to the
    exported interface:
    - "select()"
    - "unselect()"
    - "unselectAll()"
    - "reframe()"
    - "setShowSelection()"
    So now we can easily highlight components from Python (to ease
    debug).
* New: In Hurricane::CellViewer, create a proxy for the CellWidget
    "reframe()" function.
2020-09-11 12:55:51 +02:00
Jean-Paul Chaput 0b5ce309eb Implement QuadTree pruning to speedup the display of huge designs.
When displaying big designs, the drawing was very slow because all
the graphical objects were browsed *before* deciding if they were
big enough for display. So we introduce a new mode of working of
the QuadTree to that the ones with areas *below* a certain thresold
just get skipped. Of course, the previous behavior must be preserved
(when the threhsold is zero or negative) as most of the time, we
*want* *all* the objects under an area, not only the biggest ones.
For now, in CellWidget, the visibility threshold is set to 20 pixels.
With this, we can display the Libre-SOC "test_issuer" of 100Kgates
in between 20 to 30s.

* New: In Hurricane::QuadTree_GosUnder collection & locator, add a
    "threshold" argument so that QuadTree which both area sides are
    below that lenght will be ignored (no walkthrough at all).
      Zero (or negative) threshold means  that no QuadTree will be
    pruned, we get back to the previous behavior.
* New: In Hurricane::Slice::getComponentsUnder(), add the threshold
    argument (with a default to 0).
* New: In Hurricane::Cell::getInstancesUnder(), add the threshold
    argument (with a default to 0).
* New: In Hurricane::Query, added support for the threshold parameter.
    In doQuery(), instances that have *both* side under the threshold
    are pruned (slightly different from QuadTree areas).
* New: In Hurricane::CellWidget::_redraw(), set the visibility
    threshold to 20 pixels (arbitrary, must be parametrized).
* New: In Hurricane::Cell, added destroyPhysical() method.
    Remove *all* physical components and the DeepNets (so make
    a virtual *unflatten*) in the correct dependency order.
    In particular, RoutingPads, that relies on Occurrence over
    physical components must be destroyeds *before* the entity
    they are based on is destroyed.
2020-08-27 19:14:44 +02:00
Jean-Paul Chaput 083e58d953 Add CRL::Catalog and Net::getRoutingPads() to the Python interface.
* New: In CRL::PyAllianceFramework, export getCatalog(), in PyCatalog,
    export the getState(name) method and add a PyCatalog_Link().
    In PyCatalogState, add PyCatalogState_Link(), cannot use the
    macro because of the C++ name resolution operator (Catalog::State).
* New: In Isobar, export the RoutingPads collection to the Python interface.
* New: In Hurricane::Net, export the getRoutingPads() method to the
    Python interface (hence the need of the previous export).
2020-08-21 16:00:50 +02:00
Jean-Paul Chaput ea38329de1 * Bug: In CellCollection::Cell_HyperNetRootNetOccurrences::progress(),

    ine the locator constructor but forgotten in the progress().
2020-08-03 19:35:21 +02:00
Jean-Paul Chaput be2f9f8a45 Bug fix: Always select the Pin as best RoutingPad component.
* Bug: In Anabatic::Configuration::selectRpComponent(), always select
    the Pin as the best component. It is mandatory for a block that
    we pick up the terminal at the periphery and not one deep inside
    the block.
* Bug: In Hurricane::RoutingPad::setOnBestcomponent(), same rule as
    in Anabatic, if there is any, the Pin must always be the best
    RoutingPad component.

2020-08-02 18:07:27 +02:00
Jean-Paul Chaput 17ecfd823b Enhanced techno rule support. Inspector support bug fix.
* Bug: In Hurricane/Commons.h, modify the getRecord<>() templates so
    that for both vector<Element> and vector<Element*>, the individual
    record created for each element are donne with pointers. That is,
    for the vector<Element> case, we take a pointer.
      As a general policy, except for the POD types, always use pointers
    or references to data in the records/inspector. Never uses values
    that can call the copy constructor.
      Suppress INSPECTOR_PV_SUPPORT() macro, keep only
    INSPECTOR_PR_SUPPORT().
      Provide value support only for getString<>() template.
      This value & copy constructor problem was causing a crash when
    trying to inspect Hurricane::AnalogCellExtension.
* New: In Hurricane::Technology, change the API of the PhysicalRule,
    now we can only create/get PhysicalRule, but setting the value of
    the rule itself must be done on the rule.
      Enhance PhysicalRule to provide for stepped rules, non isotropic
    and ratio rules.
      Merge TwoLayersPhysicalrule in PhysicalRule, much simpler to
    suppress the management of derived classes. That means that we
    loose a little memory as some fields are mutually exclusive.
    Not a problem considering that there will not be so many of thoses
    objects.
* New: In CRL/helpers.analogtechno.py, enhanced DTR support for rules
    like:
      ('minSpacing'  , 'metal1', ((0.4,20.0), (0.8,1000.0)), Length, 'REF.1')
      ('minEnclosure', 'metal1', 'cut1', (0.2,0.3)         , Length, 'REF.2')
      ('minDensity'  , 'metal1', 0.30                      , Unit  , 'REF.3')
      The DTR parser has been updated, but not the oroshi.dtr Rule
    cache for analog components. Given a rule name, the value used
    will be the horizontal one of the first step.
* Change: In hurricane/doc/hurricane, re-generate the documentation
    with updated support for Technology & PhysicalRule.
2020-07-21 11:22:04 +02:00
Jean-Paul Chaput 235a9eecea Adjustements to the ExceptionWidget behavior.
* Change: In Hurricane::ExceptionWidget,
    - Use a QTextLabel instead of a QLabel, make it "look like" a QLabel.
    - Always display using text mode. Not HTML (to preserve indentation).
    - Make the text of the error message selectable.
    - Make it resizable.

Jean-Paul Chaput 4483766f34 Enabled support for track positionning in analog Transistor devices.
* New: In Analog, new Parameter derived class "StringParameter",
    to support strings. Also added to the Python interface.
* New: In Analog::Transistor, added StringParameters for specifying
    track positions. They are named "G.t", "S.t", "D.t" and "B.t".
* New: In Oroshi/wip_transistor.py, now read the track positionning
    devices parameters.
* New: In Karakaze/AnalogDesign.doDevice(), read an optional 14th
    parameter holding the track positions (example in ADC-SAR).

Jean-Paul Chaput dc25159cd6 Bug fix, reset Cell flags after unrouting an analog design.
* Bug: In Bora::SlicingNode::clearGlobalRouting(), as we are unrouting the
    cell, the flags set up by Katana must be reset. The Cell is no longer
    "Terminal" and it's nets are "Un-flattened".

Jean-Paul Chaput bd4ace7cc8 Full update of the generated documentation. 2020-04-27 14:14:03 +02:00
Jean-Paul Chaput 7e7e7170ba Improve symmetry management for analog designs.
* Bug: In Hurricane::NetRoutingState::getSymValue(), outrageously bad
    computation of the symmetric coordinate when the value was superior
    to the axis... (shame on me).
* Change: In Anabatic::Disjkstra::load(), for symmetrically paired nets,
    check that the axis of symmetry is *outside* the searchArea.
      Otherwise, the two mirrored areas overlaps and the two nets will
    unescapably be on top of each other. Issue a warning but still
    continue.
* Change: In Anabatic::Vertex::isRestricted(), allow perpandicular
    wire to go through struts or thin (less than one routing pitch)
    node. May have to recheck in the future and restrict to struts
    only.
* Bug: In Bora::HVSlicingNode::updateSymNetAxis(), rescursive call in
    child node was not systematically done (bad curly brace position).
      Also checks that symmetries are not empty before accessing the
    front element (one less core dump).
2020-04-10 12:15:23 +02:00
Jean-Paul Chaput a50b6ce317 More PEP8 compliant Python code. Start rewrite Python/C++ wrappers.
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
    Move towards more Python PEP8 compliance:
      * All indentations sets to 4 spaces (in progress).
      * In plugins, remove messages about software collections
        and RHEL (too many case could wrongly lead to that).
	Instead systematically uses "helpers.io.catch()".
      * Put in lowercases all modules names. Note that C++ exported
        modules *keep* their Capitalized names (to preserve the
	identity with the C++ namespace).
      * When making import, use full path.
      * Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
    the one ending in ".conf". Keep those who have not been ported
    to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
    C preprocessor macros by C++ templates. Applied first to configuration
    from VLSISAPD.
      This is unfinished business, just a limited demonstrator for now.
      It is installed as a separate Python library "Cfg2" which do not
    interact with the rest of Coriiolis.
      The end goal is to fully remove boost and merge VLSISAPD useful
    components directly inside Hurricane.

Jean-Paul Chaput e9ce33a857 Resistor integration.
* New: In Isobar::PyResistor, manage type RPOLYH and RPOLY2PH.
* Change: In Hurricane::Resistor, rename plate nets from "PIN1" and
    "PIN2" into "t1" and "t2" (try to respect uniform naming scheme).
* New: In Karakaze/AnalogDesign.py, support for reading Resistor
    parameters.
* New: In Orosshi, ResistorSnake.py imported from Mariam Tlili's work
    and associated Resistor.py to make parameter conversion.
      Currently we only uses vertical layout for resistors.
      Added METAL2 horizontal terminals for resistors.
2020-03-30 12:40:29 +02:00
Jean-Paul Chaput 837de500aa Compliance with Debian 10 Buster.
* Change: In all tools, FindTOOL.cmake, no longer use LIB_SUFFIX to
    search for tool libraries but try "lib64/" then "lib/".
* Change: In bootstrap/socInstaller.py, take Debian 10 into account.
* Change: In bootstrap/docker, move from Debian 9 to Debian 10.
2020-03-19 18:18:35 +01:00
Jean-Paul Chaput a12d88040a Capacitor support, at last.
* Change: In Hurricane::DbU::setGridPerLambdas(), allow the grid per
    lambda to be even. Needed when using nsxlib libraries that are
    drawn using a "half lambda" (two lambdas to get an Alliance lambda).
* New: In Oroshi/python, integrated capacitors. Modifications and
    correction from Mariam's code:
    * No need to redefine __setattr__() on CapacitorUnit.
    * Pitch horizontally & vertically (symbolic routing tracks) the
      devices.
    * Put the horizontal access tracks on the routing pitch.
    * Sets the horitontal metal2 wires as external components and
      NOT the capacitor plates themselves.
    * Makes the size (plates) of the unit capacitor a multiple of
      the foundry grid, not a floating number...
    * Correct the net ownership of horizontal tracks in
      drawHRoutingTracks().
    * Simplification & put error management directly inside of
      __isCapacitorUnitOK__().
* New: In Karakaze/python/AnalogDesign, capacitor spec now include
    the dummy parameter.

Jean-Paul Chaput dfe4d80b60 Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).

* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
    for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
    create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
    them by "TerminalNetlist" one, especially Collections. Now we have
    two clear sets of Collections to walkthough the layout or the
    netlist.
      Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
    "TerminalNetlist" collections and apply the new semantic to the
    locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
    TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
    non terminal netlist instances to flag fully placed sub-blocks
    as terminal for the netlist. Only then remove the feed cells
    from unplaced instances. Previously, the feed cells where stripped
    even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
    Python None object when we do not want to pass one but need to
    have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
    renaming.
2020-03-10 12:10:53 +01:00
Jean-Paul Chaput 59ee8358ca First working recursive place & route (Libre-SOC ALU16 benchmark).
* New: In Hurricane::Cell::isLeaf(), a leaf cell was defined as one
    without instances. Now it can be software defined with the
    "FlattenLeaf" state. If it is flagged "flatten leaf" is will be
    considered as a leaf by the trans-hierarchical walkthrough.
      This flag is also set for Cells in the Alliance CATAL.
* New: In Hurricane::Cell_LeafInstanceOccurrences::progress(), add a
    test to prune leaf cells.
* Bug: In Hurricane::getComponentOccurrences(), when calling the
    locator constructor, the "withLeafCells" argument was forgotten
    and was getting the value of "doExtraction" (wich, fortunately,
    was the same).
* Change: In Hurricane::HypreNet_LeafPlugOccurrences::progress(),
    prune the leaf cells instead of the terminal ones.
* Change: In Hurricane::HypreNet_ComponentOccurrences::progress(),
    prune the leaf cells instead of the terminal ones.
* New: In Hurricane::Cell, add a "useFlattenLeaf" mode to take into
    account or ignore the "FlattenLeaf" flag when doing trans-
    hierarchical walkthrough.
      Not sure if it shouldn't be systematic.
* New: In Etesian::toColoquinte() and other, activate the "FlattenLeaf"
    mode for all walkthough. So we can stop at already placed sub-blocks.
* Bug: In Etesian::toColoquinte(), when placed sub-block where present,
    the number of instances was under estimated, so the instance array
    was oversized and the end went unitialized. So we were getting all
    kind of strange behavior from Coloquinte...
      Now throw an exception if the number of instances differs from
    the computed size.
* Bug: In Etesian::toColoquinte(), as for the instance array, now
    correctly compute the size with the ecluded nets (supplies, clocks).
* Bug: In Etesian::resetPlacement(), event if the Cell is unplaced,
    go through the instance list to remove the potential feed cells.
      The netlist is written back after placement *with* the feed
    cells added. So, when loading again, they where cluttering the
    netlist and giving feed redefintions warning. They also generated
    erratic behaviors.
* New: In Anabatic::NetBuilderHV, added configurations for:
    * 1G_1M1_1PinM3
    * 1G_xM1_1PinM2
    * 2G_xM1_1PinM2
    * doRp_AccessNorthPin
* New: In Anabatic::NetBuilderHV, added Pin management in SingleGCell.
* Bug: In Anabatic::NetBuilderHV::_do_xG_1PinM3(), the North/South
    global routing configuration was forgotten (only East/West).
* Bug: In Katana::TrackFixedSegment, the blockage net was a static
    variable initialized at the first run. So we were getting stuck
    with the blockage net of the first cell to be routed. Of course,
    it did show only when Katana was run multiple times in the same
    process.
2020-03-04 00:50:18 +01:00
Jean-Paul Chaput 757b95343b Support for full Database clear & restart.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
    Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
    unload Python modules prior to a full reset.
      Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
    the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
    the library list is empty. Should never occur except in case of a
    botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
    the catalog of a library and "saveCells()" to write back the cells.
      Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
    of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
    (improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
    instead of a static one. This allow for it's correct resetting
    across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
    parser call. Needed to support database reset.

* New: In Hurricane::DBo, add an object counter to be sure that when
    we perform a reset, no remaining DBo is allocated. This is different
    of the object id which is ever increasing.
      Note that, at reset, we check against "1" remaining element as at
    this point only Database is still allocated.
      Add a new "resetId()" method. MUST NEVER BE CALLED except by
    DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
    of all the libraries in reverse hierarchical depth order.
    Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
    DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
    a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
    loop of deletion over a collection for the shared pathes.
      Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
    prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
    various "qtFree()" of the sub-objects.
2020-02-29 16:55:14 +01:00
Jean-Paul Chaput 0dc98dfce3 Migrating doc from Sphinx towards Pelican.
* Change: In documentation, now generate the overall documentation using
    Pelican instead of Sphinx. This allows to have an unified approach
    between the coriolis.lip6.fr website and the local documentation.
      So we keep using "only" two doc generators: doxygen & Pelican.
2020-02-03 17:44:15 +01:00
Jean-Paul Chaput 26610ba80c Fixe bad Python exception catch for C-launched scripts.
* In Hurricane::Viewer::Script::runFunction() & callFunction(), when the
    script returns NULL, do not immediately return but first check if an
    exception has been set. If so, print it *then* clear it.
      Due to not clearing the exception we where seeing one later with
    no relation to the true problem.
* In Oroshi/python/Rules.py, a bad test structure was discarting all the
    "no layer rule with physical length" in the loading process. It was
    blocked by the physical unit rule special cases.
2019-12-19 01:18:11 +01:00
Jean-Paul Chaput e711ce8dd2 More configuration parameters for P&R Conductor, for experimenting.
* Change: In Hurricane::Viewer::ExceptionWidget & CRL/python/helpers/io.py,
    downscale icons for non-HiDPI screen.
* Change: In CRL/etc/common/display.py, change the display threshold of
    METAL1 layer so it do not appear at high scaling.
* New: In Etesian, activate the "setFixedAbHeight()" feature and export it
    to Python. Allows to increase the space margin at constant height.
      To be used by the P&R conductor.
* Change: In Unicorn/cgt.py, when running a script, insert the current
    working directory at head of the sys.path, not at the end. So installed
    modules do not shadow local one.
* New: In Anabatic::Edge, new accessor "getRawcapacity()" to know the full
    capacity of the edge, that is, the real maximum number of tracks that
    can go through the associated side.
* Change: In Katana/BloatProfile/Slice::tagsOverloaded(), bloating policy
    change, now bloat all the instances under the GCell, not only the first
    one.
* Change: In KatanaEngine::runGlobalRouter(), restore the search halo growth
    policy to expanding of 3 GCells every 3 iterations.
      New metrics displayed, the edge wire length length overload.
* Change: In cumulus/plugins/ConductorPlugin.py, now accepts the following
    configuration parameters:
      - "anabatic.globalIterationsEstimate", maximum number of global
        iterations during the bloating computation passes.
      - "conductor.useFixedAbHeight", tells wether the additionnal blank
        space must be added so the aspect ratio is kept or the height is
	kept (and the block become wider).
    Disable the display of "rubber" to unclutter a little the view.

Jean-Paul Chaput 8cc2d9f06e Allow 45/135 degrees edges in Hurricane::Rectilinear. 2019-12-09 13:44:19 +01:00
Jean-Paul Chaput 68e45bc5ab Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
  1. Compliance with clang 5.0.1, tested with the RedHat collection
     llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
     with Xcode & macports. The bootstrap install system has been modificated
     accordingly.
  2. The basic support for routing density driven placement. Related
     features are:
     * Bloat property. Each Occurrence of an Instance can be individually
       bloated. This property not attached to any tool to allow the placer and
       router to share it as wanted. Nevertheless, it is defined in Etesian.
     * BloatProfile in Katana, add individual Bloat properties to Instances
       occurrences based on the East & North overflowed edges of each GCell.
     * Support in ToolEngine for a "pass number" of a tool. This pass number
       is mainly used to make "per pass" measurements. The MeasureSet system
       is improved accordingly to support multiple values of a same measure.
     * Embryo of "P&R Conductor" to perform the place & route loop until the
       design is successfully placed. May be the first brick of a Silicon
       Compiler.

* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
    the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
    instance occurrence BloatProperty dependency.
      Added option support for the "llvm-toolset-7" collection to build
    against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
    for first & second arguments must be called with <const T> and <const U>
    as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
    not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
    template has a static member "_name". Clang did show that the template
    for this static number has to be put inside the namespace where the
    template *is defined* (i.e. Hurricane) instead of the namespace where
    it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
    be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
    (clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
    signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
    (clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
    Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
    current working directory in the sys.path as in certain configuration
    it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
    encountering a RoutingPad on a top-level Pin Occurrence. The segment
    was generated in the wrong direction, creating DRC violations on the
    "mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
    Now, each kind of measure can accept multiple values put in a vector.
    The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
    indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
    addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
    name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
    that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
    was wrong, it was always returning true, which broke the "strick weak
    ordering" of the comparison.
      This was producing a core-dump in GCell::updateDensity() when sorting
    a vector<>. The end() iterator was being dereferenced, leading to the
    problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
    whose axis is perpandicular to the symmetry axis was wrong
    ("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
    and selectBloatedInstances() to automatically select segments from
    overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
    between global and detailed.
      Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
    driven placement.
2019-12-09 01:57:44 +01:00
Jean-Paul Chaput a3b006a809 Add templates for derived Key in DBo::CompareById::oprator() [gcc 8].
* Change: In Hurricane::DBo::CompareById, starting from gcc 8, the compare
    function is checked inside the STL map<>/set<> so the lhs & rhs arguments
    are of the exact type of the Key, even excluding a base class.
      So now, in complement of the normal function, we provide a templated
    comparison functor in CompareById.
2019-12-01 13:31:33 +01:00
Jean-Paul Chaput 5f53487036 Added RPOLYH & RPOLY2PH types to ResistorFamily. 2019-11-22 11:32:48 +01:00
Jean-Paul Chaput f38945d200 Various bug fixes (Selection, Measures/Histogram, helpers).
* Bug: In CRL/python/helpers/__init__.py, in textPythonTrace(), when an
    ErrorMessage was catched, the trace parameter was not correctly
    extracted leading to an "exception in exception".
* New: In Isobar/PyCell, exported Cell::getNonLeafInstanceOccurrences()
    collection.
* New: In Isobar/PyTransformation, type is now built so the tp_compare
    is linked to the C++ operator==().
* Change: In Hurricane::SelectionModel, Hurricane::SelectionWidget and
    CellWidget, no longer use Occurrences but directly the Selector property.
      We also use the Selector to know if an Occurrence is selected by
    looking at that property on it's Quark. This avoid a very lengthy
    search in vector when there is many elements (say > 10000).
      NOTE: This is a bad implementation as there is a confusion between
    beeing selected (that is, having a Selector property attached to
    an Occurrence Quark) and being actually displayed as selected.
    This lead to awkward implatation of the various "toggle" methods.
    Have to rethink that more clearly later.
* Bug: In CRL::Histogram, the non-inline template full specialisation
    of Measure<Histogram> must not be put in the header but in the module
    to avoid multiple definition and link failure. They are actually
    real, classic functions.
2019-11-22 00:24:47 +01:00
Jean-Paul Chaput 92edd9ba31 New implementation for the Python hash and compare methods.
* Change: In Hurricane::Isobar/PyHurricane.h, make the hash function use
    the DBo id whenever possible instead of the object pointer, fall back
    to it for standalone objects (Box like one). The DirectHashMethod()
    macro generate a C style function (linkage) which call a template
    function "getPyHash<>()" that uses a SFINAE mechanism to select
    the right variant.
      Create two comparison macros DirectCmpByPtrMethod() and
    DirectCmpByValueMethod() to customize the comparison for objects that
    have C++ operator==(). So now two boxes with the same contents will
    be seen equal by Python. For DBo objects we keep the previous
    comparison by C++ pointer.
2019-11-14 23:56:01 +01:00
Jean-Paul Chaput 1e4b8b4647 Added support for extra resistor rules in Hurricane::Technology.
* New: In BasicLayer::Material, added "info" kind of material for layers
    that are only informationals (i.e. not real GDS one). Created to
    store geometric combination of layers, this is a temporary solution.
      Have to define a clearer semantic for that.
* New: In CRL/helpers/AnalogTechno.py, new "Count" type for count numbers
    that must not go through DbU::Unit converter. They are plain integers,
    but stored in DbU::Unit (keeping track of that semantic is left to
    the user).
2019-11-13 16:09:38 +01:00
Jean-Paul Chaput 88235dc3a4 Added Resistor support. Completed Capacitor & Resistor support in Bora.
* New: In Analog, added Analog::ResitorFamily & Analog::Resistor classes.
* New: In Analog, added inspector support for all Parameter classes.
* New: In Analog, new FloatParameter class (for resistor value).
* New: In CRL/etc/scn6m_deep_09/devices.py, added resistor device.
* New: In Oroshi, support for Resistors, stub for ResistorSnake generator.
* New: In Bora::DNodeSets, added support for Resistor devices.
* Change: In Bora::DSlicingNode, rename setNFing()/getNFing() into
    setBoxSetIndex()/getBoxSetIndex() for semantic coherency.
* New: In Karakaze/python/AnalogDesign.py, added support for Resistor.
    Change in addDevice(), the span which was only meaningful for
    transistor devices is replaced by a parameter argument.
      The parameter argument has to be consistent with the device type.
2019-11-12 02:21:03 +01:00
Jean-Paul Chaput 8035b31f27 First stage in analog capacitor integration
* Bug: In Technology::getPhysicalRule(), if the named layerdo not exists,
    throw an exception instead of silently putting a NULL pointer inside
    a rule.
* New: In Hurricane/Analog, new parameters classes for capacitor devices:
    - Analog::Matrix, a matrix of null or positives integers to encode
      capacitor matrix matching.
    - Analog::Capacities, a list of float values for all component of a
      multi-capacitor.
* New: In Hurricane::Script, add a "getFileName()" method to get the full
    path name of the Python module.
* Change: In Analog::LayoutGenerator, completly remove the logger utility
    as it is no longer used. Simply print error messages instead.
* Change: In Analog::MetaCapacitor, rename top & bottom plate 'T' & 'B'.
    Accessors renamed in "getTopPlate()" & "getBottomPlate()".
* New: In Analog::MultiCapacitor, complete rewrite. Makes use of the
    new parameters "capacities" and "matrix". Dynamically generates it's
    terminals as we do not know beforehand how many capacitors could be
    put in it.
* Bug: In isobar/PyHurricane.h, in Type object definition, do not prepend
    a "Py" to class name (so the keep the C++ name).
* Change: In CRL/etc/scn6m_deep_09/devices.py, add entry for the new
    capacitor generator.
* New: In oroshi/python/ParamsMatrix, add a "family" entry in the [0,0]
    element to distinguish between transistor, capacitor and resistor.
    (this is the matrix of values returned to the LayoutGenerator after
     device generation).
      Now have one "setGlobalParams()" function per family.
* New: In oroshi/python/Rules.py, added DTR rules needed by capacitors.
    Catch exceptions if something wrong append when we extract the rules
    from the technology.
* New: In Bora, the devices are no longer *only* transistors, so the
    possibles configurations are no longer defined only by a number of
    fingers. We must be able to support any kind of range of configuration.
      So the explicit range of number of fingers is replaced by a base
    class ParameterRange, and it's derived classes:
      - Bora::StepParameterRange, to encode the possible number of fingers
        of a transistor (the former only possibility).
      - Bora::MatrixParameterRange, to encode all the possible matching
        scheme for a capacitor. As there is no way to compress it, this
	is a vector of Matrix (from Analog).
* Change: In Bora::DSlicingNode::_place(), the ParameterRange has to be set
    on the right configuration (through the index) before being called.
      The generation parameters are taken from the active item in the
    ParameterRange.
* Change: In Bora::NodeSets::create(), iterate over the ParameterRange
    to build all the configuration. Adjustement to the routing gauge
    pitchs are moved into the DBoxSet CTOR to save a lot of code.
      Semantic change: the index in the NodeSets is now the index in
    the associated ParameterRange and no longer the number of fingers
    of a transistor.
      Check that the ParameterRange dynamic class is consitent with the
    device family.
* Change: In Bora::DBoxSet, same semantic change as for NodeSets, the
    number of finger become an index in ParameterRange.
      In DBoxSet::create(), now also perform the abutment box adjustement
    to the RoutingGauge, if possible.
* New: In Karakaze/python/AnalogDesign.py, add support for Capacitor
    devices.
2019-11-07 17:05:49 +01:00
Jean-Paul Chaput 2c73cfe76c Migrating the initialisation system to be completely Python-like.
* New: In bootstrap/coriolisEnv.py, add the "etc" directory to the
    PYTHONPATH as initialization are now Python modules.
* New: In Hurricane/analogic, first groundwork for the integration of
    PIP/MIM/MOM multi-capacitors. Add C++ and Python interface for the
    allocation matrix and the list of capacities values.
* Change: In Hurricane::RegularLayer, add a layer parameter to the
    constructor so the association between the RegularLayer and it's
    BasicLayer can readily be done.
* Change: In Hurricane::Layer, add a new getCut() accessor to get the
    cut layer in ViaLayer.
* Change: In Hurricane::DataBase::get(), the Python wrapper should no
    longer consider an error if the data-base has not been created yet.
    Just return None.
* Bug: In Isobar::PyLayer::getEnclosure() wrapper, if the overall
    enclosure is requested, pass the right parameter to the C++ function.
* Change: In AllianceFramework, make public _bindLibraries() and export
    it to the Python interface.
* Change: In AllianceFramework::create(), do not longer call bindLibraries().
    This now must be done explicitely and afterwards.
* Change: In AllianceFramework::createLibrary() and
    Environement::addSYSTEM_LIBRARY(), minor bug corrections that I don't
    recall.
* Change: In SearchPath::prepend(), set the selected index to zero and
    return it.
* Change: In CRL::System CTOR, add "etc" to the PYTHONPATH as the
    configuration files are now organized as Python modules.
* New: In PyCRL, export the CRL::System singleton, it's creation is no
    longer triggered by the one of AllianceFramework.
* New: In CRL/etc/, convert most of the configuration files into the
    Python module format. For now, keep the old ".conf", but that are no
    longer used.
      For the real technologies, we cannot keep the directory name as
    "180" or "45" as it not allowed by Python syntax, so we create "node180"
    or "node45" instead.
      Most of the helpers and coriolisInit.py are no longer used now.
    To be removed in future commits after being sure that everything
    works...
* Bug: In AutoSegment::makeDogleg(AutoContact*), the layer of the contacts
    where badly computed when one end of the original segment was attached
    to a non-preferred direction segment (mostly on terminal contacts).
      Now use the new AutoContact::updateLayer() method.
* Bug: In Dijkstra::load(), limit symetric search area only if the net
    is a symmetric one !
* Change: In Katana/python/katanaInit.py, comply with the new initialisation
    scheme.
* Change: In Unicorn/cgt.py, comply to the new inititalization scheme.
* Change: In cumulus various Python scripts remove the call to
    helpers.staticInitialization() as they are not needed now (we run in
    only *one* interpreter, so we correctly share all init).
      In plugins/__init__.py, read the new NDA directory variable.
* Bug: In cumulus/plugins/Chip.doCoronafloorplan(), self.railsNb was not
    correctly managed when there was no clock.
* Change: In cumulus/plugins/Configuration.coronaContactArray(), compute
    the viaPitch from the technology instead of the hard-coded 4.0 lambdas.
      In Configuration.loadConfiguration(), read the "ioring.py" from
    the new user's settings module.
* Bug: In stratus.dpgen_ADSB2F, gives coordinates translated into DbU to
    the XY functions.
      In st_model.Save(), use the VstUseConcat flag to get correct VST files.
      In st_net.hur_net(), when a net is POWER/GROUND or CLOCK also make it
    global.
* Change: In Oroshi/python/WIP_Transistor.py, encapsulate the generator
    inside a try/except block to get prettier error (and stop at the first).

Jean-Paul Chaput 5bbeb0b062 Support for separated NDA tree. Big cleanup of the Python init system.
* Change: In Hurricane::Script, when running a script, no longer do it
    inside a Python sun-interpreter, use the current one. This way we
    no longer have our modules initialized twice or more, which was
    starting to be unmanageable (with the NDA support).
      The settings were re-read multiple time to the same value, so it
    was working, but still...
      I hope I didn't left some dangling Python objects now.
* Bug: In Hurricane::LayoutGenerator::drawLayout(), get the device abutment
    box though a Pyhon object *before* finalizing which removes that objet.
* New: In cumulus/plugins/__init__.py, add a "loadPlugins()" and static
    initialisation to preload plugins modules.
      We use that pre-loading step to append to the module __path__ attribute
    the alternate directory where a NDA covered may be found. This assume that
    the directory tree under the NDA root is identical to the one under the
    public root.
* New: In cumulus/plugins/chip/__init__.py, small utility function
    importContants() to import the constants inside another module namespace,
    to have more consise notations.
* Change: In cumulus/plugins/, in the various plugins sub-modules import
    use the full path from plugins, that is, for example:
      from plugins.core2chip.CoreToChip import IoPad
* Change: In Unicorn/python/unicornInit.py, no longer directly load the
    plugins modules, this is now done by cumulus/plugins/__init__.py.
      Instead, iterate through sys.modules for the ones starting by "plugins/"
    and try to execute a Unicorn hook, if present.
* Change: In Karakaze/python/AnalogDesign.py, update for the new Instance.create()
    prototype (added placement parameter).
2019-10-11 17:36:54 +02:00
Jean-Paul Chaput 70a3960ba5 ioNet used as "enable" should not get the name of the pad.
* Bug: In Cumulus/plugins/core2chip/CoreToChip.py, when creating the ioNet
    objects, when a signal is an enable we must not set the external chip
    net (the name for the PAD terminal) as it may be set later if it is
    also used as an individual pad.
2019-08-09 18:45:19 +02:00
Jean-Paul Chaput acc3a38f60 Support for placing *one* block of a Cell in Etesian.
* Change: In Hurricane::Cell_LeafInstanceOccurrences, add the ability to
    walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell_NonLeafInstanceOccurrences, add the ability to
    walkthrough the leaf of one specific top-level instance.
* Change: In Hurricane::Cell:
    getLeafInstanceOccurrences() and getNonLeafInstanceOccurrences(), now
    have a parameter Instance* to select the leafs we want to walk through.
    If set NULL (default value) browse through all the instances,
    as before.
* Change: In Hurricane::DeepNet, add forgotten Inspector support.
* New: In EtesianEngine, add a "block" (and Instance) attribute to allow
    the placement of one specific bloc. If we want to place the core of
    a chip and take into account the external terminals (if they are not
    already fixed as Pins at the edge of *said* block). We must place
    the core *in the context* of it's instanciation in the corona.
      Note for G. Gouvine : Pin & external RP should be taken into account
    starting at line 629 of EtesianEngine.cpp...
* New: In cumulus/plugins/chip/Chip.py, make use of the new block
    placement feature of ETesian.
* Bug: In KatanaEngine::create(), perform a pre-check to prevent trying to
    route whole chip, which is forbidden an leads to annoying core-dumps.
    Routing must take place "at most" at Corona level.
* Bug: In KatanaEngine::PowerRails, create a plane for METAL1 blockage.
    Not completely sure this was a bug...
2019-08-04 17:33:03 +02:00
Jean-Paul Chaput 1b444d8f49 In cumulus/Core2Chip.py forgot a parameter to an error message call. 2019-07-31 19:16:40 +02:00
Jean-Paul Chaput d69327d9a9 Various typos correction (courtesy of G. Gouvine). 2019-07-30 13:13:57 +02:00
Jean-Paul Chaput f528cdea4c Upgrade of Katana detailed router to support Arlet 6502.
* Change: In Hurricane::SharedName, replace the incremental Id by a hash key.
    This is to ensure better deterministic properties. Between use cases,
    additional strings may have to be allocated, shitfing the ids. Even if
    hash can be duplicated, we should be able to ensure that the absolute
    order in map table should be preserved. Supplemental strings are inserted
    in a way that keep the previous order.
* Change: In CRL/etc/symbolic/cmos/kite.conf, add "katabatic.routingGauge"
    default parameter value ("sxlib").
* Change: In CRL/etc/common/technology.conf, define minimal spacing for
    symbolic layers too (added for METAL4 only for now).
* Change: In CRL::Histogram, extend support to dynamically sized histograms.
    Add a text pretty print with table and pseudo-curve.
* Change: In Cumulus/plugins/ClockTreePlugin, create blockage under the
    block corona corners so the global router do not draw wire under them.
    This was creating deadlock for the detailed router.
      When the abutment has to be computed, directly use Etesian to do it
    instead of duplicating the computation in the Python plugin.
* New: In Etesian, as Coloquinte seems reluctant to evenly spread the
    standard cells, we trick it by making them bigger during the placement
    stage. Furthermore, we do not not uniformely increase the size of the
    cells but create a "bloating profile" based on cell size, cell name
    or it's density of terminals. Currently only two profiles are defined,
    "disabled" which does nothing and "nsxlib" targeted on 4 metal layer
    technologies (aka AMS 350nm, c35b4).
* Bug: In Knik::MatrixVertex, load the default routing gauge using the
    configuration parameter "katabatic.routingGauge" as the default one
    may not be the first registered one.
* New: In AnabaticEngine::setupNetDatas(), build a dynamic historgram of
    the nets terminal numbers.
* Bug: In Anabatic::AutoContact::Invalidate(), always invalidate the
    contact cache when topology is invalidated. In case of multiple
    invalidations, if the first did not invalidate the cache, later one
    that may need it where not allowed to do so. The end result was correct
    nonetheless, but it did generate annoying error messages.
* Bug: In Anabatic::AutoContactTurn::updateTopology(), bad computation
    of the contact's depth when delta == 2.
* Bug: In Anabatic::Gcell::getCapacity(), was always returning the west
    edge capacity, even for the westermost GCell, should be the east
    edge in that case.
* New: In Anabatic::AutoSegment, introduce a new measure "distance to
    terminal". This is the minimal number of segments separating the
    current one from the nearest RoutingPad. This replace the previous
    "strong terminal" and "weak terminal" flags.
      This distance is used by Katana to sort the events, we route the
    segments *from* the RoutingPads *outward*. The idea being that if we
    cannot event connect to the RoutingPad, there is no points continuing
    as thoses segments are the more constraineds. This gives an order close
    to the simple ascending metals but with better results.
* New: In Anabatic::AutoSegment, introduce a new flag "Unbreakable", disable
    dogleg making on those segments. mainly intended for local segments
    directly connecteds to RoutingPads (distance == 0).
* New: In Anabatic::AutoSegment, more aggressive reducing of segments.
    Now the only case where a segment cannot be reduced is when it is
    one horizontal branch in a HTee or a vertical on a VTee. Check if,
    when not accounted the source & target VIAs are still connex, if so,
    allow reducing.
* New: In Anabatic::AutoContact, new state flags CntVDogleg & CntHDogleg
    mainly to prevent making doglegs twice on a turn contact. This is to
    limit over-fragmentation. If one dogleg doesn't solve the problem,
    making a second one will make things worse only...
* Bug: In Anabatic::Configuration::selectRpcomponent(), we were choosing
    the component with the *smallest* span instead of the *bigger* one.
* New: In Anabatic::GCell, introduce a new flag "GoStraight" to tell that
    no turn go be made inside those GCells. Mainly used underneath a block
    corona.
* New: In AnabaticEngine::layerAssign(), new GCellRps & RpsInRow to manage
    GCells with too many terminals. Slacken at least one RoutingPad access
    when there is more than 8 RoutingPad in the GCell (slacken or change
    a vertical METAL2 (non-preferred) into a METAL3).
* Change: In Anabatic::NetBuilderHV, allow the use of terminal connection
    in non-preferred direction. That is, vertical METAL2 directly connected
    to the RoutingPad (then a horizontal METAL2). This alllows for short
    dogleg without clutering the METAL3 layer (critical for AMS c35b4).
      Done in NetBuilderHV::doRp_Access(), with a new UseNonPref flag.
      Perform some other tweaking on METAL1 access topologies, to also
    minimize METAL3 use.
* New: In AnabaticEngine::computeNetConstraints(), also compute the
    distance to RoutingPad for segments. Set the Unbreakable flag, based
    on the distance and segment length (local, short global or long global).
      New local function "propagateDistanceFromRp()".
* Change: In AnabaticEngine.h, the sorting class for NetData, SparsityOrder,
    is modificated so net with a degree superior to 10 are sorted first,
    whatever their sparsity. This is to work in tandem with GlobalRouting.
* New: In Katana::TrackSegmentNonPref, introduce a class to manage segment
    in non-preferred routing direction. Mostly intended for small METAL2
    vertical directly connected to RoutingPad. Modifications to manage
    this new variant all through Katana.
* Change: In Katana::GlobalRoute, DigitalDistance honor the GoStraight flag
    of the GCell. Do not make bend inside thoses GCells.
* Change: In KatanaEngine::runGlobalRouter(), high degree nets (>= 10) are
    routed first and whitout the global routing estimation. There should be
    few of them so they wont create saturations and we want them as straight
    as possible. Detour are for long be-points.
      Set the saerch halo to one GCell in the initial routing stage (before
    ripup).
* Bug: In KatanaEngine & NegociateWindow, call _computeCagedconstraints()
    inside NegociateWindow::run(), as segments are inserted into tracks
    only at that point so we cannot make the computation earlier.
* Change: In Katana::Manipulator::repackPerpandiculars(), add a flag to
    select whether to replace the perpandiculars *after* or *before* the
    current segment.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when the
    segment is fully enclosed inside a global, the longest overlap cost
    is set to the shortest global hoverhang (before or after).
      When the cost is for a global, set an infinite cost if the overlapping
    segment has a RP distance less or equal to 1 (this is an access segment).
* Bug: In Katana::PowerRailsPlane::Rail::doLayout(), correct computation of
    the segments extension cap.
* New: In Katana::QueryPowerRails::addToPowerRail(), add support for Pad.
* Change: In Katana/PreProcess::protectCagedTerminals(), apply the contraints
    to any turn connected to the first segment of the RoutingPad so the
    perpandicular constraints got propagated to the perpandicular segment...
* Change: In RoutingEvent, cache the "distance to RP" value.
* Change: In RoutingEvent::Key::compare(), sort *first* on distance to
    RoutingPad, then layer depth. If both distance to RoutingPad is null,
    then sort on segment length.
* Change: In RoutingEvent::_processRepair(), try a repack perpandicular with
    perpandiculars first (then with perpandicular last, then give up).
* Change: In SegmentFsm::bindToTrack() and moveToTrack(), set an axis hint
    when creating the insertion event.
* Change: In SegmentFsm::_slackenStrap(), add a step through slacken between
    minimize and maximum slack (wihch directly end up in unimplemented).
* Change: In Session::_addInsertEvent(), add an axis parameter needed when
    the axis of the segment is not the one of the track (case of wide
    segments or non-preferred direction).
* Bug: In Track::_preDestroy(), bad management of the TrackElement reference
    count. Destroy the segment only when reaching zero...
* Bug: In Track::expandFreeIneterval(), forgotten to manage case when there
    is a set of overlaping segments at the "end" of the track, the
    EndIsTrackMax was not set.
* Change: In TrackCost::Compare, increase the cost when an overlaping
    segment is at it's ripup limit. We should try *not* to rip it up if
    we can. Add a dedicated flag "AtRipupLimit".
* Change: In TrackElement, add proxies for isUnbreakable(), new function
    updateTrackSpan().
* New: In TrackFixedSegment CTOR, when a supply wire of METAL2 or above is
    found, make the underlying GCells "GoStraight".
* New: In TrackElement::canDogleg(GCell*), check for already done perpandicular
    dogleg on source/target (reject if so).

Jean-Paul Chaput 0df4821806 Full update of the generated documentation for version 2.3 2019-05-27 18:49:51 +02:00
Jean-Paul Chaput 4cd0bcb009 Various bug corrections to pass the alliance-check-toolkit reference benchs.
* New: In Isobar::PyCell, export the isRouted() and setRouted() to the
    Python interface.
* Bug: In CRL::Entity::parseEntity(), check that the closing parenthesis
    is the last character of the net name. Issue a more relevant error
    message.
* In Anabatic::NetBuilder::_do_xG() and all other unimplemented methods,
    throw an error if called from a derived classes instead of just
    issuing a message in the debug stream. Avoid later core dumps...
* In Anabatic::NetBuilderHV, implement the builders for GCells with
    one pin. Needed to support chip/corona routing.
* Bug: In Cumulus/plugins/Chip.py, check that coronaCk exists before
    using it.
* New: In Cumulus/plugins/PadsCorona/Side._placePad(), when routing
    a design with symbolic pads, export the chip external "pad"
    connectors to be able to perform a lvx (otherwise cougar do not
    create external nets).
      In Corona._createCoreWire(), set the minimal gap between the pads
    and the corona to 6 pitches. Empirical value to avoid DRC errors
    with symbolic pads (pxlib).
      When successufully done, mark the Corona cell as routed.
* Bug: In Cumulus/plugins/Core2Chip.IoNet, the regex for vectorizet net
    was wrong, it was allowing only one digit in the index.
* Bug: In Cumulus/plugins/Core2Chip.cmos, correct management of
    pad & corona clock nets. Correct connexion between vdde/vddi.
* Bug: In Unicorn/cgt.py, forgot to execute scripts when in text mode.
2019-05-24 23:57:22 +02:00
Jean-Paul Chaput 3fb746fbef Support for mixing real pads & symbolic core. Wrapper around s2r.
* Change: In Hurricane::Error constructors disable the backtrace generation.
    (*very* slow).
* Change: In Hurricane::Library::getHierarchicalname(), more compact
    naming. Remove the name of the root library.
* New: In Hurricane::Net, new type "FUSED", for component with no net.
    More efficient than having one net for each.
* Change: In CellViewer, BreakpointWidget, use Angry Birds icons.
* Change: In CellWidget::State, use the hierarchical name (cached) as key
    to the state. This allow to load two cells with the same name but from
    different libraries in the widget history.
* Change: In PyGraphics, export "isEnabled()" and "isHighDpi()" functions.
* Change: In CRL/etc/symbolic/cmos/plugin.conf, and
    CRL/etc/common/plugin.conf use the physical dimensions converters.
* Change: In CRL/etc/symbolic/cmos/technology.conf, make the GDS layer
    table coherent with the default Alliance cmos.rds.
* New: CRL/python/helpers/io.py, put ErrorMessage new implementation here,
    along with a new ErrorWidget written in PyQt4. It seems finally that
    PyQt4 can be used alongside Coriolis Qt widgets.
      New ErrorMessage.catch() static function to manage all exceptions
    in except clauses.
* Change: In CRL/python/helpers/, no longer use ErrorMessage.wrapPrint(),
    directly print it.
      Rewrite the utilities to display Python stack traces "textStacktrace()"
    and "showStacktrace()".
* Change: In CRL::AllianceFramework, shorten the names of the libraries.
* Change: In CRL::ApParser & CRL::ApDriver, more accurate translation between
    Alliance connectors (C record) and Hurricane::Pin objects. Pin are no
    longer made square but thin and oriented in the connecting direction.
      Use the new fused net for unnamed components.
* New: In CRL::GdsParser, implementation of SREF parsing, i.e. instances.
    Due to the unordered nature of the GDS stream, instances creation are
    delayed until the whole stream has been parsed and only then are they
    created.
      For the sake of reading back Alliance s2r GDS, we assume that any
    TEXT following a boundary is the Net name the boundary (component)
    belongs to.
      Create abutment box for Cells, computed from the bounding box, so
    the Hurricane QuadTree could work properly.
      Make use of the fused net for unnamed components.
* New: In Cumulus/plugins/chip, complete rewrite of the I/O pad management.
    Now we can mix real (foundry) pads and a symbolic core.
      To cleanly support the de-coupling between the real part and the
    symbolic one we introduce a new intermediary hierarchical level, the
    corona. We have now:
      Chip --> Pads + Corona --> Core.
      At chip level (and if we are using real pads) the layout is fully
    real (excepting the corona).
      The Corona contains everything that is symbolic. It has symbolic
    wires extending outward the abutment box to make contact with the
    real wires coming from the pads.
      In the pad ring we can use corners instances (or not), pad spacers
    or directly draw wires between connectors ring pads.
      Provide two flavors: placement only or full place & route.
    WARNING: If routing in a second step, *do not route* the *Chip* but
    the *Corona*.
* Change: In Cumulus/plugins/clocktree, give the modified Cell an
    additional extension of "_cts" (Clock Tree Synthesis) instead of
    "_clocked", to follow the common convention.
* New: In cumulus/plugins/S2R.py, encapsulate call to Alliance S2R and
    reload the translated Cell in the editor.
* New: In cumulus/plugins/core2chip, provide an utility to automatically
    create a chip from a core. To work this plugins must have a basic
    understanding of the pad functionalities which may differs from
    foundry to foundry. So a base class CoreToChip is created, then for
    each supported pad foundry a derived class is added. Currently we
    support AMS c35b4 and Alliance symbolic cmos.
* Bug: In Anabatic::Configuration, read the right configuration parameter
    "anabatic.topRoutinglayer" (Katana), and not the one for Katabatic...
* Change: In Unicorn/cgt.py, process the plugins in alphabetical order
    to ensure a reproductible ordering of the menus...
2019-05-22 14:34:32 +02:00
Jean-Paul Chaput 1360479eed Switch place in menus between Katana & Kite (Katana becomes the default).
* Change: In Hurricane::CellViewer, reorganisation of the to level menus.
    Add "Misc." and it's two sub-menus "Beta" and "Obsolete".
* Change: In GraphicKiteEngine::addToMenu(), set Kite in the obsolete menu.
* Change: In GraphicKatanaEngine::addToMenu(), set Katana as the standart
    router.
2019-05-10 11:59:21 +02:00
Jean-Paul Chaput 43629a6c1c Tweaking Layer & RoutingGauge management. Allow negative track indexes.
* Bug: In Hurricane python module, forgot to add the Segment type.
* Change: In Isobar/layer.getEnclosure() wrapper check and cast the Layer
    argument into BasicLayer.
* Change: In CRL::RoutingGauge::getLayerGauge(Layer*), getLayerType() and
    getLayerDirection() no longer check layer identity based on layer
    mask instead of just Layer* pointer. To allow a unified call wether
    the layer is real or symbolic.
* Change: In CRL::RoutingLayerGauge::getTrackIndex() and getTrackPositon(),
    no longer consider negative indexes as invalid and reset them to
    zero. The check for out of bound index is now left to Anabatic &
    Katana.
* Change: In CRL/RoutingGauge.getRoutingLayer() and getContactLayer(),
    more detailed error message.
* Change: In CRL/RoutingLayerGauge.getTrackIndex() and getTrackPosition(),
    indexes are now signed long instead of unsigned.
2019-05-10 11:52:42 +02:00
Jean-Paul Chaput 2beee8a25c Bug: Compopent creation inside a Collection loop In Cell::flattenNets().
* Bug: In Hurricane::Cell::flattenNets(): Same error again, do not create
    components while iterating over the components Collection.
      Now RoutingPad of top nets are create outside the loop as they must.
2019-05-10 11:48:33 +02:00
Jean-Paul Chaput f6c840fd59 ISPD05 loading speed issues. IO PAD support for LEF importation.
* New: In Hurricane::IntrusiveMap, introduce IntrusiveMapConst which allow
    to search with a "const Key&" instead of a "Key", sparing the copy
    construction of the Key.
* Change: In Hurricane::Cell::NetMap, use the new kind of map with
    "const Name&" key access. This speeds up the Cell::getNet() method
    by suppressing one copy construction of a Name, which are costly
    after all...
      Should review the whole code to use "const Name&" everywhere it
    is possible.
* Change: In Hurricane::Entity & Hurricane::DBo, displace the unique
    identifier from Entity to DBo (move up to the base class).This
    to allow us to build deterministic map of DBo requireds in
    UpdateSession (which is built upon a SharedProperty).
      WARNING: This break the JSON database exportation support, do not
    use it until fixed/rewritten.
* Change: In Hurricane::Layer, add an attribute to know if a layer is
    associated to a blockage. Modificate accordingly PyLayer and
    BasicLayer.
* Change: In Hurricane::SharedProperty, the set of owners (DBo*) is now
    stored in a std::set sorted on the objects Ids, instead of a simple
    vector. The linera search time through the std::vector was starting
    to show (ISPD05 bigblue1).
* Bug: In Isobar::PyInstance, make full contructor signature (5 arguments)
    conform to the C++ one. It was only accepting the four first and
    forcing the placement status to be FIXED.
* Bug: In CRL/etc/symbolic/ispd05/kite.conf, update for the new configuration
    requirements where all distance must be converted into DbU in the
    file itself (use "helpers.l()", "helpers.m()"). Apply to the cell &
    routing gauges.
* Bug: In CRL/etc/symbolic/ispd05/technology.conf, update for the new
    configuration. "helpers.initTechno()" *must* by called first thing
    in this file in order for the Technology to be created.
* New: In CRL::AllianceFramework, add matchCellGauge() &
    matchCellgaugeByHeight()
* New: In CRL::CellGauge, add a flag to distinguish gauges meant for
    IO Pads and an "isPad()" predicate.
* Change: In CRL::Ispd05Bookshelf, flush the UpdateSession stack every
    1000 elements additions. Maybe not necessary now the the UpdateSession
    property relies on a std::set instead of a std::vector.
* New: In CRL::LefImport, support for SITE and match/create the appropriate
    CellGauge on the fly. Specific support for MACROS that are flagged PAD.
      Add a dedicated post-treatment for PAD connectors, extend them toward
    the boundary of the nearest abutment box side. Tested only on AMS 350nm
    c35b4 for now.
      This part is most likely to be tweaked for every kind of real foundry
    pad that we may encounter...
* Change: In EtesianEngine::findYSpin(), use the C++ "for" construct to loop
    over Collections.
* Change: In Unicorn/cgt.py, register the Python/C++ tutorial support by
    default.
2019-04-22 12:16:16 +02:00
Jean-Paul Chaput 3e4430c089 Fix huge memory link in Collection iterator.
* Bug: In Hurricane::Collection::iterator, the iterator use a locator from
    a getLocator() not wrapped inside an auto_pointer like GenericLocator.
    So the destructor of the iterator must take care of the deletion.
      This was showing more and more as we converted forEach() into the
    C++ 11 for syntax.
      Seems to decrease the memory use by almost a factor 2...
* Bug: In Dijkstra::_cleanup(), as a double security, cleanup the queue.
2019-03-23 15:43:00 +01:00
Jean-Paul Chaput 3a2916b5e6 Improved clock-tree support for variable pitch routing gauges.
* New: In Hurricane::Isobar::PySegment, added wrapper for getOppositeAnchor().
* Bug: CRL::PyRoutingLayerGauge, Python wrapper of getTrackPosition() was
    in fact returning getTrackNumer().
* Bug: In Katana::PowerRailsPlanes::Rail::doLayout(), add the half minimum
    distance to the blockage segments extensions. Was causing too near
    VIAs is cmos45.
* Change: In cumulus/plugins/ClockTree, correctly manage routing gauge when
    the lower pitches (M2/M3) is different from the upper one (M4/M5).
    But we still can only do sxlib compliant gauges because we do not
    handle a switch in preferred routing directions.

    on Polygon and Rectilinear.
* Bug: In Hurricane::Rectilinear, forgot implementation of getContour().
    Add a new accessor getPoints().
* Bug: In CRL::Blif::load(), do not always enforce translation towards
    VHDL names. When loading LEF+gds it may change the Cell names between
    the two stages so the gds layout do not get added to the LEF Cell
    phantom.
      Now add a boolean enforceVhdl argument (may be a flag in the future).
* Bug: In ::GdsStream::operator<<(Cell*), forgot to drive the Rectilinear.

Jean-Paul Chaput fac01b10aa Compare function key adjustement for Rule in Technology.h
* Bug: In hurricane/Technology.h we define a set of UnitRule with a
    custom sorting function. STL starting with gcc 8, introduce a type
    checking of the compare function. And as everithon is template, we
    must use the exact key type and no longer a base type... So we create
    an overload for each derived type :-(
2019-03-04 12:45:02 +01:00
Jean-Paul Chaput e704306cad More robust deterministic netmap. Use classic string hash.
* Change: In Hurricane::Cell::NetMap, the hash function is now based on
    the string itself and not on the id of the SharedName. We now may
    remove the id attribute of the SharedName.
      This to ensure a more robust deterministic behavior. The sort
    order do not depend on whether we did use names before or not.
2019-02-26 19:56:29 +01:00
Jean-Paul Chaput 9f69230837 Correct CellWidget & CellPrinter to be really WYSIWYG.
* Change: In Hurricane::CellWidget, new "isPrinter" attribute to know if
    the CellWidget is used as a device for printing.
      New function copyExtensionsGos() to duplicate the ExtensionGo drawing
    callbacks. This is a temporary hack until the ExtensionGo are made static
    to be shared by all CellWidgets.
      In _redraw(), the DrawingQuery flags were not correctly reset between
    different stage of the drawing. This was resulting of uneeded walkthough
    of the slicing tree, along with incorrect display of some of the layers
    (i.e. rubbers where diplayeds when ExtensionGos where active).
* Change: In GraphicKatanaEngine, fine tune the display of GCells for printing
    CellWidget.
* Change: In Hurricane::CellPrinter, copy all the settings from the palette
    of the reference (graphic) CellWidget into the printer CellWidget.
    Also copy the ExtensionGos callbacks so we can print them. Use the
    new CellWidget attribute "isPrinter" for the callbacks to be able
    to adapt to Printer settings.
* Change: In Hurricane::Time::getStringTime(), only print two decimals
    for time durations.

Jean-Paul Chaput 2f9a7076cb Forgoten hurricane analog generated documentation. 2018-11-29 12:03:26 +01:00
Jean-Paul Chaput c76fa034ba Implementation of a red-black tree and an interval tree.
* New: In Hurricane::RbTree, template for red-black tree. Standard
    implementation but well integrated in the Hurricane database and
    ready to be derived (both iterator and Collection support).
* New: In Hurricane::IntervalTree, template for interval tree, derived
    from RbTree.
* New: unittests tool to perform unit tests.
* Change: In Bora::ChannelRouting, now implemented with IntervalTree.
    There is something suspicious here : the "thick" version of
    addWireoccupation() seems never to be called. Have to check the
    wide wire support implementation.
2018-11-07 23:48:43 +01:00
Jean-Paul Chaput fcd6d69a2f Analog integration part II. Analog place & route (slicing tree).
* Change: In Hurricane::CellWidget, set the minimal size to 350 pixels
    to fit my normal DPI secondary screen...
* Change: In Hurricane::Error(), reactivate the backtrace generation by
    default. Seriously slow down the program each time an Error is to
    be constructed.
* Bug: In Analog::Device::preCreate(), check for NULL Technology before
    attempting to use it.
* Change: In Hurricane/Analog, remove all '*Arguments*' classes and their
    Python interface. It was an obsoleted way of passing devices parameters
    to the Python layout generators (located in Oroshi). Now we just get
    them straight from the Device with the getParamter() method.
* Change: In CRL::System CTOR, add Python pathes for Oroshi & Karakaze.
* Change: In Oroshi/Python/WIP_*.py layout generator scripts, remove
    all uses of the "Arguments". Directly access the parameters through
    the device itself. Make the checkCoherency() with identical arguments
    as of layout().
* New: Bora tool that performs analog place & route. Based on a slicing
    tree representation. It is the thesis work of Eric Lao.
      Code beautyfication and some programming cleanup.
* New: Karakaze tool, provide the Python base class AnalogDesign used
    to build an analog design. Create/configure devices and assemble
    them in a slicing tree.
* Change: In Unicorn/cgt.py, display the stack trace in case of an
    ImportError exception as well as for other exceptions.
      Add Bora to the set for included tool engines.
2018-10-18 18:10:01 +02:00
Jean-Paul Chaput 3f73b9d033 Anlog integration part I. Atomic devices support (transistors).
* Change: In boostrap, remove support for Chams.
* New: In Hurricane::Technology, added support for DTR rules, UnitRule,
    PhysicalRule and TwoLayersPhysicalrule. Added devices descriptors and
    models descriptors (for Spice). Spice description is not used yet
    but kept anyway in case of future use.
* New: Hurricane::Analog whole library and it's Python interface. This
    provides support for transistors, capacitors and resistors. Only
    transistor support is fully implemented as of now.
* New: In CRL/python/coriolisInit.py, read configuration files for the
    Analog extension (analog.conf & devices.conf). Thoses are optionals
    and a simple warning is issued if not found.
      Added helpers/AnalogTechno.py DTR loading helper.
      Add analog configuration files for 180/scn6m_deep_09.
* New: Oroshi tool that provides actual layout drawing for transistors.
2018-10-01 16:52:17 +02:00
Jean-Paul Chaput dc01b60d5c Force the locale LC_ALL to be POSIX (in Hurricane::DataBase).
* Problem: In LEF/DEF, the parsers makes use of the libc "strtod()" which
    is now localized. So, if your environment is set up for French, the
    decimal separator is not '.' (dot) but ',' (comma). So floating
    numbers in LEF/DEF file are not longer recognized as such, causing
    the parsers to fail with a LEFPARS-1 error.
      To avoid that, we force the LC_ALL environment variable to POSIX
    in Hurricane::DataBase::create(). So first things that happens when
    Hurricane starts, is the environment to be reset.
      Strangely, when I try to setup only LC_NUMERIC with setlocale()
    it doesn't work. There is something I'm missing there...
2018-09-28 12:12:18 +02:00
Jean-Paul Chaput b53511ea83 Minor adjustements for analog device checker (test of AMS c35b4).
* Change: In CRL::GdsStream, no longer export empty Cells as structures,
    to avoid empty cells in Cadence. To prevent meta-transistors to be
    exported as real physical objects.
      Also put a hard-coded test to prevent exporting "control_r" model
    which is made of AMS standard cells for "amsOTA".
* Change: In CRL/PyRoutingGauge, export the isHV() and isVH() methods so
    the Stack can access it.
* Change: In Hurricane/PyCellViewer, export the removeHistory() method.
    When a Cell is deleted, it must be also removed from the editor
    history. This should be take care of automatically, but for now
    we make it manually through scripts.
* Bug: In Anabatic::NetBuilder::doRp_accessAnalog(), the gauge offset
    was not taken into account when creating initial Contact on
    RoutingPad. The program self corrected afterwards, but with the
    display of a disgraceful message.
* Change: In Anabatic::Configuration and Session, export the gauge offsets.

Jean-Paul Chaput 094cb8a132 Improved handling of short nets (fully included in one GCell).
The short net mode degrade the routing in some cases. This will be
fixed in a next batch of commits.

* New: In Hurricane::NetRoutingProperty, added "ShortNet" flag for Nets
    that are completly inside *one* GCell.
* Bug: In CRL::BlifParser::Model::staticInit(), when looking for the
    output of zero and one cell, also skip the blockage net (as well as
    automatic and supplies).
* New: In Anabatic::AutoSegment, added "ShortNet" flag to know if the
    segment is part of a short net (fully included in *one* GCell).
      Also add accessor/mutators for the _analogMode flag (was it ever
    used before?).
* New: In Anabatic::NetBuilder::singleGCell(), if a RoutingPad is
    vertically small, add a vertical segment to give it some slack.
* New: In Anabatic::Dijkstra::_materialize(), detect "short net" as
    they have only one GCell in their source list...
* Bug: In AnabaticEngine::_loadGrbyNet(), reset the AutoSegment
    "short net" and "analog mode" creation flags between two different
    nets.
* New: In Katana::Configuration, added dedicated ripup for short net
    segmnts.
* New: In Katana: partially implemented support for "short dogleg", that
    is dogleg that are always kept in same metal because they connect
    neighboring perpandicular tracks. Not finished neither activated
    yet.
* New: In Katana::TreckElement and derived, export the the *short net*
    support from AutoSegment.
* Bug: In Katana::RoutingEvent::_processRepair(), when a segment is
    successfully inserted, re-process any perpandicular that is in
    repair state, as it may have a new chance to be placed.
* New: In Katana::SegmentFsm::slackenTopology(), always reject short nets.
* Bug: In Katana::Track::check(), correctly handle wide segments instead
    of issuing false check messages.

Jean-Paul Chaput 767407736d Add a fully generated documentation in the git repository.
* Change: In all tools supplying documentation, as we use some specific
    software to create the doc, they may not be available, or worse, be
    and incompatible version. So, by default, we install the files shipped
    with the git repository. To force a full doc rebuild, use the "--doc"
    flag of ccb.py.
2018-06-06 18:42:26 +02:00
Jean-Paul Chaput 1887f45135 Exported Polygon::getSubPolygons() to Python.
* New: In Hurricane::Isobar::PyPolygon, export the getSubPolygons()
    method. Makes a list of list (maybe tuple should have been better
    to prevent user's rewrite).
* Change: In documentation/examples/scripts/, update polygons.py to
    serve as a very basic test-bench for Polygon, manhattanhization
    and sub-polygons display.
2018-06-03 12:55:28 +02:00
Jean-Paul Chaput 4f089ffdea Polygon internal normalization. Sub-polygons for GDSII driver.
* Change: In Hurricane::Polygon, store the points so they are always
    ordered in the counter-clockwise (trigonometric) direction. This
    simplicificate internal computations.
* New: In Hurricane::Polygon, added getSubPolygons() methods, that
    split horizontally the polygon in sub-polygons of about 1000
    vertexes. This is mainly to be used by the GDSII driver to abide
    to the XY 4000 points limitation.
* New: In Hurricane::Isobar, export support for Point collections so
    the various contour Polygon methods can be created in the Python
    interface.
* New: In CRL::GdsDriver, split the Polygons into set of sub-polygons
    of less than 1000 vertexes. Use the getSubPolygons() method.
* Change: In stratus1.dpgen_RF2, makes more explicit error messages
    about placement by displaying the faulty vs. expected coordinates.
2018-06-03 11:47:31 +02:00
Jean-Paul Chaput ea16b5a556 Added GDSII parser. Component/Polygon reorganisation.
* New: In CRL, implement a GDSII parser. The complete syntax is supported,
    but only a few subset is really taken into account. It is intended to
    load the layout of standard cells only. The interface of the cell is
    provided through a LEF file and it complete layout through the GDSII.
      The loader work in a Library way. It takes a Hurricane library as
    argument and search in the GDSII library structures with a name
    matching the Cell of the library and complete them.
* Change: In Hurricane::Component, put the Contour methods at Component
    level so we can use them in a generic way in the CellWidget drawing
    primitives.
* New: Hurricane::Rectilinear polygon, for small rectlinear polygons.
    Should be less than 100 vertexes. For bigger ones, use Polygon
    which allows slanted egdes.
* Bug: In CRL, freepdk_45/technology.conf, there seems to be an incoherency
    bettween the GDSII layer numbers as defined in the Cadence FreeePDK45.tf
    file and the one used in the supplied layout of the GDSII cells.
      For now, we align on the GDSII cells to get nice layouts, but it
    has to checked.
2018-05-20 15:47:34 +02:00
Jean-Paul Chaput 4a65a8d4e7 Added GDSII driver. Bug in Blif parser.
* New: In CRL, implement a true GDSII driver. The driver is directly under
    CRL and do not use an intermediate structure in vlsisapd. The ASCII
    GDSII is removed.
      Huge polygons are not supported yet. Have to be split up in
    sub-polygons of less than 4000 vertexes.
      Symbolic layout can be exported to give a rough idea of the layout
    but RDS expension is not applied. Symbolic composite layers are
    expansed into their basic layers so the design *looks* normal.
* Deprecated: In CRL, remove all traces of the old XML configuration
    parsers. No one needs them now, including Chams.
* Bug: In CRL::BlifParser, before blindly loading the model of a subckt
    from disk with AllianceFramework, checks if it is in the Catalog
    first. Load with AllianceFramework only cells that are in the
    Catalog.
      This prevent a file of the same name than a model to be loaded
    shadowing the later defintion of the model in the Blif file.
      All this is due to the fact that Blif could be non-ordered for
    the models...
* Change: In Hurricane::BasicLayer, the "extract number" is replaced
    by a GdsLayer and GdsDatatype to generate accurate GDS files.
    Even if datatype is 0 most of the time.
      Update all the "technology.conf" files in CRL to provide those
    two numbers.
2018-05-15 13:12:00 +02:00
Jean-Paul Chaput 41c9959e30 Added support for diagonal wires (45° and 135°)
* New: In Hurricane::Diagonal, new object to represent 45° and 135°
    segments (X routing). Althought they have source & target, they
    are not articulated like Horizontal & Vertical, due to the
    combined displacement of X and Y (diagonal).
      Maybe we should create a common class for all the polygons
    to make "::getContour()" a method.
      Now we could represent self capacitances and high frequency
    wires.
2018-05-07 13:46:44 +02:00
Jean-Paul Chaput 0902b21f23 Added support for huge approximated polygons (for photonics).
* New: Hurricane::Triange as been renamed into Hurricane::Polygon.
    Add support for convex polygons. Polygon are approximateds by
    excess by a manhattan rectilinear polygon (with potentially
    thousands of vertexes). To reduce the memory footprint,
    compaction techniques reducing by at least a factor 4 has been
    implemented. We could go further by only storing the non-repetitive
    part of the edge (defined by the integral fraction dY/dY).
    We will see, if the program slows too much.
      The manhattan approximate is always computed but displayed
    only if the polygon grid step is greated than 4 pixels.
      The level of approximation of the polygons can be controlled
    through the "DbU::_polygonStep" parameter.
* Change: In CRL/coriolisInit.py and CRL/helpers/Technology.py, regroup
    all DbU related parameters into "technoConfig" (i.e. suppress
    "viewerConfig"). Update all the relevant technology.conf configuration
    files.
      Change the loader behavior so that "technoConfig" is read first
    and is now responsible for creating the Technology of the DataBase.
* New: In Hurricane::CellWidget, added support for displaying mahanttanized
    polygons.
* Change: In documenation/scripts/expample/polygons.py, perform (I hope)
    a comprehensive test of the polygons (check all slopes, clockwise and
    conter-clockwise).
* New: In Hurricane::DbU, added template to manage vector<> of DbU.
    Support for the "polygonStep" parameter.
2018-05-04 17:06:41 +02:00
Jean-Paul Chaput 6b4baad8b9 More non-deterministics behavior corrections.
* Bug: In Hurricane::Cell_SubCells collection, order the set<> of Cell
    with Entity::CompareById instead of pointer values.
* Bug: In Hurricane::Component_ConnexComponents::Locator, sort the
    set<> of Components with Entity::CompareById instead of pointers.
* Bug: In Hurricane::Occurrence::operator<(), uses Ids to compare
    both _entity and _sharedPath. Check for NULL pointers.
* Change: In Hurricane::IntrusiveMap, add a debug output in _resize()
    like for IntrusiveSet.
      Note to myself : despite their names, InstrusiveMap are hash
    tables and not map<> in the STL sense.
* Bug: In CRL Core, Vst parser, sort the CellVectorMap on Ids.
* Bug: In CRL::NamingScheme::toVhdl(), sort the set<Cell*> models on Ids.
* Bug: In CRL::toVhdlName(), sort the set<Cell*> models on Ids.
* Bug: In CRL::getInstancesCount(), sort the map<Cell*,size_t>
    gatesByMaster on Ids.
2018-04-08 16:58:55 +02:00
Jean-Paul Chaput 0fa6f8be9b Determinism correction of Hurricane, CRL core & Katana.
* Bug: In Hurricane::Cell::uniquify(), a set<Cell*> sorted on pointers
    was remaining. Now sorted on Entity::Id.
* Bug: In CRL::VhdlEntity, in the driver, the components where driven
    in pointer order (set<> again). Now use ids.
* Bug: In CRL/etc/scn6m_deep_09/technology.conf, the symbolic extentions
    for VIAs and layers were wrong. Have to be multiplied by two.
* Change: In AnabaticEngine, AutoContact and AutoSegment LUTs are now
    sorted on Entity::Id. Should not have had any impact, but better
    safe than sorry.
* Change: In KatanaEngine, Symmetric contraint map<> is now sorted on
    Entity::id. Idem for TrackSegmentLut.

Jean-Paul Chaput dd4a01fe70 Validating channel routing mode (two metals) on SNX.
* New: In Hurricane::Entity, add an id counter limit and a memory size
    limit. The two limits are checked only when a new Entity object is
    created. This should help avoiding massive memory links.
* New: In CRL Core, add a "crlcore.groundName" and a "crlcore.powerName"
    parameter to specify the name of the ground/power signals to be
    created if they are missing in a Cell. For Alliance libraries it
    would be "vss" & "vdd" (default values), but for real technologies,
    it is often "gnd!" & "vdd!".
      The Blif parser is modificated to make use of it.
* Bug: In AnabaticEngine::unify(), set the resulting unified segment in
    the  center of the GCells common side. Gcells under a segment are
    found by using the edge that cover the segment axis. When we have
    a "bend" GCell stack and the axis is wrong, they could be ommited.
      This was causing deleted segments to be not removed from some
    Edges, then core dump.
* Change: In Anabatic::AutoSegment::create(), smarter choosing of the
    reference contact, select the fixed or terminal one instead of
    always the source one.
* New: In Anabatic::Edge::isEnding(), new function to check if a
    segment going through an Edge is starting/ending in either source
    or target GCell of the edge (active only when running in channel
    mode).
* New: In Anabatic::Edge::add(), a segment takes part in the occupancy
    only if it is not ending in either source or target (channel mode
    only). The occupancy due to terminal is pre-computed in Katana.
* New: In Anabatic::Edge::ripup(), in channel mode, never ripup a
    segment which is ending in either source or target (we *have* to
    access this edge to connect to the terminal).
* Bug: In Anabatic::GCell::hcut() and vcut(), force the update of
    the Edge which is on the side that will get splitted by the cut.
    It's capacity will be reduced to it must be updated.
* Change: In Anabatic::GCell::updateGContacts() add a flag to conditionnally
    update horizontals or verticals only. We may require only a partial
    update when resizing the GCell in only one direction.
      This, again, related to the fact that we compute the GCells under
    a segment thanks to it's axis position, so we need to be very careful
    when modificating axis.
* Change: In Katana::Block::resizeChannels(), only update GContact vertical
    position. Do not disturb X positions of segments.
* Bug: In Katana::GlobalRoute::DigitalDistance, in channel mode, some
    Edges can have a zero capacity, but still be reachable if the net has
    a terminal in either source or target. Look for this case and return
    a distance of zero instead of "unreachable". This was causing the
    global routing not to complete in channel mode.
      For computing the edge distance, makes the vertical edges much more
    long (10 times) than the horizontal ones as the vertical capacity is
    very limited. Hard coded for now, should make it a parameter in the
    future.
* Change: In KatanaEngine::annotateGlobalGraph(), decrease the capacity
    of edges with reserveCapacity for each terminal inside a GCell.
    Both north and south edges are decreased as we a terminal will
    block both north and south edges.
      As a counterpart, the Edge capacity is not decreased when the
    global router connect to a terminal.
* Change: In Katana::RoutingEvent::revalidate(), when in repair stage,
    do not expand the slack for horizontal segments in channel mode.
    So they may not overlap the standard cell row.
* Bug: In Stratus documentation, do not use the french option in babel,
    the documentation is in english!
* New: In Documentation, added Hurricane/Python tutorial, part for drawing
    layout.
2018-03-16 16:20:04 +01:00
Jean-Paul Chaput 592c098ab2 Basic support for FreePDK 45 completed.
* New: In Commons, inspector support for std::pair<T,U>.
* New: In Hurricane::Layer, ContactLayer & ViaLayer, support for non
    square VIAs. The hole (cut) remains square, but the various metal
    extensions can now be different in X and Y. The ::getEnclosure()
    method now takes a flag EnclosureH / EnclosureV.
* New: In Hurricane::DbU, inspector support for:
         std::pair<DbU::Unit,DbU::Unit>
	 std::array<DbU::Unit,3>
     Must be defined here as DbU do not exists yet in Commons.h
* Bug: In Hurricane::Interval::getSize(), when the interval is "full span",
    do not return the difference between min and max, but directly DbU::Max.
    (the previous result was -1 !)
* New: In CRL Core Python/Technology.py, support for non square VIAs in
    the configuration files. Applied to FreePDK 45.
* New: In CRL::RoutingGauge, added a "symbolic" flag to tell if a gauge
    is for symbolic layout or not. Exported to Python.
* New: In Anabatic::AutoHorizontal::updatePosition(), differentiated
    computation for soure or target taking account of the VIA extension
    in the right segment metal (due to non-square VIAs).
* Change: In Anabatic::AutoHorizontal::_makeDogleg(), the dogleg is
    UP for HV gauges and DOWN for VH.
* New: In Anabatic::AutoSegment::_initialize(), create a cache of the
    various extension length for each layer (viaToTop, viaToBottom,
    viaToSame).
      New implementation of getExtensionCap() using the previous cached
    extension table. See updatePositions().
      New static functions to access the extension cache in the header:
    getViaTotopCap() ...
* Change: In Anabatic::AutoSegment, in various update methods, updateOrient()
    must always be called *before* updatePositions() as extensions are
    dependant on source/target.
* New: In Anabatic::AutoSegment::getEndAxes() compute the position of the
    first source and last target position (center/axes) on an *aligned*
    set of segments.
* New: In Anabatic::AutoSegment, add a new state flag SegAxisFixed to
    signal segments that can be put on only one track. Specific case
    to VH gauge for a M1 vertical terminal with a M2 vertical segment.
    The M2 is effectively bound to the M1 axis position.
* Bug: In Anabatic::NetBuilderVH::_do_xG_xM1_xM3(), in case of E/W global
    and only one RoutingPad the connexion to the RoutingPad was duplicated.
    It was valid, but totally stupid.
* Bug: In Anabatic::Session::_canonize(), for an aligned segment set,
    intersect the user constraints from all segments instead of only
    considering the canonical one.
      Issue a warning about too tight constraints only for symbolic
    gauges. It may be correct for the real ones.
* New: In Katata::DataNegociate::update(), more accurate computation
    of the perpandicular free interval. Use segment extension cap
    calculation. Create a special case for fixed axis segments allowing
    them to find alternative free interval, try under source and under
    target as they are likely to be draggable segments.
* Change: In Katana::Manipulator::relax(), use the extension cap value
    to compute the axis of the perpandicular segemnts.
* Change: In Katana::Manipulator::moveUp(), now move up the whole set
    of aligned segments instead of just the canonical one.
* Change: In Katana::NegociateWindow::loadRoutingPads(), more accurate
    TrackMarkers insertions for fixed terminals.
* New: In Katana::RoutingEvent::Key::Compare::operator(), segments with
    fixed axis are processed prior to any others.
* New: In Katana::RoutingEventLoop, store segment pointers instead of
    ids to generate more accurate error messages.
* Change: In Katana::RoutingPlane::create(), perform local track
    assignment only for HV gauges.
* Change: In Katana::SegmentFsm::_slackenLocal(), add a "dragMinimize"
    step in the automaton. Mutliple states transitions can occurs in
    a row if an action fails.
* New: In Katana::Session::_toIntervalAxis(), normalize interval
    bounds so they are on track positions (by shrinking the interval).
* Bug: In Katana::TrackMarker CTOR, the weigh computation was wrong.

Jean-Paul Chaput ba3ddafdf5 Adjustements for analog routing.
* Change: In Anabatic::GCell::doGrid(), remove the "3 slice height"
    limit (for small digital analog blocs).
* Bug: In Anabatic::NetBuilder::setStartHook(), perform a check for
    a RoutingPad still on a Plug. Diplay an error instead of crashing.
* Bug: In CRL::RoutingLayerGauge::getTrackIndex(), the upper bound
    of the track interval must be included instead of excluded.
* New: In Hurricane::Cell, add a StayOnPlugs flags for flattenNets().
    To keep the RoutingPad occurrences on Plug instead of selecting
    physical components.
* New: In Isobar::PyNet, add setAutomatic() and isAutomatic() to the
    interface.
* Bug: In Katana::protectRoutingPads(), do not create protections on
    PinOnly layers (mostly metal1).

Jean-Paul Chaput 95aba574a5 Happy New Year 2018 ! Update license years... 2018-01-06 17:55:44 +01:00
Jean-Paul Chaput 864b031b6a Disable backtrace generation in Hurricane::Error constructor.
* Change: In Hurricane::Backtrace constructor, add a boolean parameter
    to enable/disable the actual backtrace generation.
* Change: In Hurricane::Error constructor, disable by default the
    backtrace generation. The backtrace is useful when the Error is
    thrown, and the program therefore stopped. But in many case we
    just issue the error message on the console and try to continue.
    But if the backtrace is enabled, it terribly slow down the
    program.
      Have to think about an clean way to re-enable the trace only
    when the exception is thrown.
2018-01-06 15:13:20 +01:00
Jean-Paul Chaput 24d8fe5957 Cleaner support for real technologies (Hurricane, CRL Core configuration).
* Change: In Hurricane::Technology, in all the layer connexity methods
    (getLayers(), getMetalAbove(), getCutAbove(), getViaBetween(), ...)
    the "useWorking" parameter is replaced by a more accurate "useSymbolic".
      BEHAVIOR CHANGE: formerly, if a symbolic layer was requested, and
    none was found, NULL was returned. Now, if the symbolic layer is not
    found, we try to return the associated real one (same layer mask,
    but not flagged as symbolic, and usually with a lowercase name).
      All thoses changes have been propagated to Python bindings.
* Change: In Hurricane::BasicLayer and derived classes, rename the
    "isWorking" attribute into "isSymbolic" (to match the technology
    renaming).
* Change: In Hurricane::Cell::flattenNets(), ignore power, ground and
    blockage nets for the flatten.
* Change: In CRL Core, in coriolisInit.py and Technology.py helpers,
    rename the tables describing the technology as follow:
      - symbolicLayersTable --> compositeLayersTable
      - workingLayersTable  --> symbolicLayersTable
      - symbolicRulesTable  --> layersExtensionsTable
    This is to give the table names a more clearer semantic after
    merging real technologies configurations (testbench AMS c35b4).
      In particular, we need to define a composite layer for the
    real VIAs, and not only the symbolic ones. And with correct
    enclosures expressed in real dimensions (microns).

Jean-Paul Chaput 24d5e9f172 The min debug level has to be high (10000) and not zero.
* Bug: In Hurricane the ::tstream class must be initialized with a
    minLevel of 10000 instead of zero, as the minLevel go *towards*
    zero as the debug slice [min:max[ is expanded by DebugSession.
      This default value must be repeated in the CRL::System CTOR
    and in the coriolis2/etc/commons/misc.conf.
* Bug: In Hurricane::IntrusiveSet, uses "tsetw(n)" dedicated cdebug
    stream manipulator instead of the STL one.
2017-12-21 17:29:29 +01:00
Jean-Paul Chaput 4c57b0651a Modularize the global to detail routing converter.
* New: In Anabatic, rename GCellTopology to NetBuilder, expose  the class
    (no longer in a local namespace).
      NetBuilder become a base class performing the walkthrough the Net
    tree. Derived class are tasked to build routing for specific gauge.
      NetBuilderHV is created to manage all gauge with metal2 horizontal
    and metal3 vertical.
      In our terminolgy we consider that the first routing metal is
    metal2. Metal1 is used inside the standard cells.

* New: Hurricane::DataBase::getCell() method to search a cell through
    all the libraries of *all* the frameworks, not just Alliance.
    Also exported in Python interface.
* Bug: In Technology::getNthMetal() the function was not returning the
    right metal, there was an offset of one. And when the offset was
    0, no metal was even returned. Same fix goes for getNthCut().
      The fault was in Mask<>::nthbit().
* Change: In Hurricane::CellWidget, the initial window size is too tiny.

    of rejecting them all. This bug was making the Cell::flattenedNets()
    to do nothing in digital mode.

2017-06-14 10:46:54 +02:00
Jean-Paul Chaput 8d4fdf3471 TrackCost clean support for symmetric and wide segments.
* New: In Katana::TrackCost, the TrackElement and it's optional
    symmetric are now kept as attribute of a TrackCost. The cost
    is completly computed inside the constructor.
      TrackCost now support any mix of symmetric event and wide
    segments.
      The cost is now computed by adding directly to the current
    one instead of creating secondaries that are merged afterwards.
    As a consequence, remove all copy construction and merge
    capabilities.
      All the various methods used to compute the cost are renamed
    "addOverlapcost()" in all the various related objects.
      As a reminder, the overal cost method call is as follow:
        1. TrackCost constructor on a TrackElement.
           2. Call TrackElement::addOverlapcost()
              3. For all Track under the TrackElement, call
                 Track::addOverlapCost()
                 4. For all other TrackElement intersecting with
                    the overlap interval call:
                    TrackElement::incOverlapCost()
                    5. The callback overlap function for segments
                       is called (defined in NegociateWidow).
      Don't confuse:
      - TrackElement::addOverlapCost(), which compute the cost of
          inserting the segment inside a track (or a set of).
      - TrackElement::incOverlapCost(), which compute the cost of
          overlaping with this already inserted segment. It is the
          other way around of the previous one.
* Change: In Katana::SegmentFsm, use a vector of pointer to TrackCost
    instead of an object to avoid copy construction.
2017-06-10 12:27:25 +02:00
Jean-Paul Chaput 3e825cc228 Katana routing algorithm adjustements for analog routing.
* Bug: In Hurricane::Interval, the ::getSize() method was returning a negative
    length when the Interval was empty. Now return zero. This was causing
    slight cost functions side effect when computing the overlap of a segment
    with another one belonging to the same net (i.e. shareDelta)
* Bug: In Katana::AutoSegment::computeOptimal(), checks that the optimal
    position for the axis is indeed inside the GCell interval.
* Bug: In Katana::DataSymmetric::getSymmetrical(Interval&), reverse the shrink
    applied to GCells sides. Interval are of the type [min:max[ so after
    symmetric transformation they become ]smax:smin]. Apply a correction so
    that they are [smax:smin[ and could be merged with the paired interval
    (the one without symmetry applied).
* Bug: In katana::TrackCost::consolidate(), the overlap (now) always positive,
    and must be *substracted* to the "delta" (not *added*).
* Bug: In Katana::_computeNetOptimals(), now skip the already processeds
    AutoSegments instead of re-processing them.
* New: In Katana::AutoSegment::computeOptimal(), improved computation of
    the axis hint:
      - For analog net, propagate through the simple doglegs to find
        attractors.
      - Restrict the allowed interval to the union of GCell sides and
        segments constraints that are terminals.
      - Consider a local as "long" if it's length exceed 20 the P-pitch.
        (maybe make that a tool parameter).
2017-05-23 00:20:31 +02:00
Jean-Paul Chaput e78c3f21ef Added analog type on segment NetRoutingProperty.
* New: In Anabatic_AutoSegments collection, added a Flag to the constructors
    to allow different behavior between digital and analog modes.
      For "Aligneds" and "Perpandiculars" collections, now manage a new
    Flag WithDoglegs to follow aligned globals through local doglegs
    (for analog nets).
      Adjust the log level of collections to 144 (formerly 145).
* New: In Anabatic::AutoSegment, new flag SegAnalog for segments that are
    part of an analog net.
      Note that with this flag, we reach the 32 bits limit...
* Change: In Anabatic::Constants, Flags are now declared as BaseFlags
    objects and *not* uint64_t. This avoids overload resolution problems with
    arithmetical overload of the operators.
      The BaseFlags/Flags types are now completly "isolated" from the
    uint64_t, it has the advantage of showing where unwanted previous implicit
    conversions where occuring.
* Change: In Katana::Constants, Flags values are now of BaseFlags type instead
    of uint64_t.
* Change: In Anabatic::Dijkstra, lots of log cleanup.
* Change: In Anabatic::GCell::getSide(), make the "shrink" parameter visible
    to allow to substract the topmost and rightmost track for axis span
    computation in AutoSegment::computeOptimal(). Used for analog mode.
* Change: In NetRoutingState, added a flag for analog mode. Use uint32_t
    for the flags type.
* New: In Isobar, export the NetRoutingState and NetRoutingExtension objects.
2017-05-20 12:33:12 +02:00
Jean-Paul Chaput c44c6b13f3 Adjust Katana event sort. CMake detection of Python 2.7 only.
* Change: In all top CMakeLists.txt, force the use of Python 2.7 as
    we do not compile against 3.x flavors. Do not use the "EXACT"
    flags as it will not recognize 2.7.x versions.
* Change: In Katana::RoutingEvent::Key::Compare(), preliminary
    experiments shows that the best sorting order is:
      - Lower layer first (i.e. M2 -> M3 -> M4 -> ... )
      - Longer segments first.
      The later seems to be counter-intuitive. Guess is that placing
    the small ones first generate a more important fragmentation of
    the big ones. They are placed too early and are difficult to move
    afterwards.
      Another feature to test is *not* inserting pushed left/right
    segments if they are not *already* routed.
* Change: In PyKatanaEngine.runNegociate() now takes a flag argument,
    provided through the new PyKatanaFlags exported object.
    (doChip.py must be changed accordingly)
2017-05-11 17:26:56 +02:00
Jean-Paul Chaput f1b2035cb0 Support for profiling the priority of events in Kite & Katana.
* New: In Katana::Configuration, added "katana.profileEventCosts" to
    triggers the event's profiling.
* New: In Katana::NegociateWindow::_negociate(), save a profiling
    trace of all the events and their priority, separated by metal,
    for later analysis (see doChip.py in alliance-check-toolkit).
* New: In Katana::RoutingEvent::Key::Compare(), start implementing
    new segment freedom degree functions.
* Change: In Hurricane::Net::_getString(), put a more complete
    information about the Net instead of just only it's name.
* Bug: In Katana, reorder the various stages so that they are
    executed in the exact same sequence as in "doChip.py" so now
    routing in graphic mode and text mode gives exactly the same
    results.
* Bug: In Katana::PyKatanaEngine, runGlobalRouter do not take any
    argument.
2017-05-09 18:33:55 +02:00
Jean-Paul Chaput db8e51524f Deterministic destruction of Components.
* Change: In Hurrican::Component::_preDestroy(), the cascaded destruction
    of slaves Components and subsequent ring merge and Rubber creation
    was using set<> sorted on pointer values. This was making the order
    of destruction of the slaves components non-deterministic. Now the
    sets are sorted according to their id (see Entity).
* Change: In Hurricane::SharedProperty, the _ownerSet is now a vector<>
    instead of a set<>. This will slow the search process, but hopefully
    this is needed only during construction/destruction of a Property
    so the slow down shouldn't be too much.
      This has also an impact on Hurricane::Relation.

Jean-Paul Chaput ef69a6d586 Support for symmetric routing in Anabatic/Katabatic.
* New: In Katana::SegmentFsm, the object is now able to handle two events
    at the same time. The master and it's symmetric. When there is no
    symmetric, the corresponing data is just left blank. This makes a
    bigger object, but as there is only one when running, it is not an
    issue.
      Candidates tracks are now an vector of array<2> (pairs), the
    TrackCost::Compare() functor has to be wrapped through CompareCostArray.
    The compined TrackCost of the two tracks is accumulated into the first
    element.
      Everything related to events gets duplicated: _event is now _event1
    and _event2, and so on.
      As there can be now two Manipulator actions done with SegmentFsm,
    this class now completly hide the Manipulator level from the
    RoutingEvent processing.
      New function ::bindToTrack() to perform the track insertion.
* New: In Katana::TrackCost, add a new ::merge() function.
* New: In Katana::TrackElement and Katana::TrackSegment, add symmetric
    management. Allows to know if a TrackElement has a symmetric and to
    access it.
* New: In Katana::DataSymmetric, add new overload for ::getSymmetrical()
    to handle DbU::Unit and intervals.
* Change: In Katana::RoutingEvent, remove all direct uses of Manipulator
    objects. Now any change to the event associated segment must go through
    call to Segment Fsm.
* Change: In Katana, adjust the debug level so internal informations are
    put below level 156.
* New: In Hurricane::DbU, in ::getValueString(), special display when the
    value is Min or Max (more helpful than a gigantic number).

* Change: In Hurricane::BaseFlags, store flags in uint64_t instead of
    unsigned int because we start to need more than 32 different flags
    in some tools.
* New: In ::getString() & ::getRecord() templates, add support for
    std::array<>.
* Change: In CRL::ToolEngine, add support for timer (time & memory
    measurements) displaced from Katabatic. This way all ToolEngine
    can use this feature. The _postCreate() method display the
    memory just after ToolEngine allocation.
* Change: In Etesian::EtesianEngine, make use of the ToolEngine
    builtin timer (remove the local one). Forgot to call the base
    class _postCreate() and _preDestroy().
* Change: In Anabatic::AnabaticEngine, make use of the ToolEngine
    builtin timer (remove the local one).
* New: In Anabatic, new AutoSegments_Connecteds() collection. This
    Collection allows a deterministic walkthough *all* the AutoSegments
    connected either to source or target of one AutoSegment.
* New: In Anabatic::AutoContactTerminal::isEndPoint() to check if an
    AutoContactTerminal is the *only one* anchored on a RoutingPad,
    thus being a true "end point" and not a kind of feed-through.
* New: In Katana::KatanaEngine, added support for symmetric nets.
    Created new class DataSymmetric to store symmetric information
    of a net (mainly the paired AutoSegments).
      Added KatanaEngine::runSymmetricRouter(), for now only build
    the DataSymmetric informations. More to come...
* Change: In Katana::GraphicKatanaEngine::_runTest(), now perform
    symmetric information building the non-symmetric routing.

    of the process. There is also code for reading /proc/[pid]/mmap
