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 ea94175eb4 In Entity, add Python bindings for "isBound()" and "getId()". 2020-09-30 11:50:09 +02:00
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.

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(),
skip Nets that are inside Terminal Netlist master cells. Was done
    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 18:12:52 +02:00
Jean-Paul Chaput 3996a8e15d Change: In Hurricane::CellViewer, rename "beta" menu to "alpha". 2020-08-02 18:08:14 +02:00
Jean-Paul Chaput 0745498505 Export the Pin name and direction to the Python interface.
* New: In Hurricane::PyPin, export ::getName() and ::getPlacementStatus().
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 f2a60768ca Export Entity::getId() to the Python interface. 2020-06-06 12:13:57 +02:00
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 b553aae8ad Correct icon sizing for normal definition display in BreakPointWidget. 2020-05-10 11:46:54 +02:00
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.
2020-04-08 11:24:42 +02:00
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.
2020-03-15 17:56:09 +01:00
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).
2019-10-28 18:09:14 +01:00
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.
