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.

Jean-Paul Chaput bbcf14eb5a First step in supporting ISPD18 detailed routing benchmarks.
* Change: In CRL::DefImport, added callback to read the DEF UNITS statement
    and perform a correct length conversion. Previously set to read pseudo
    lambdas in hundredth of microns.
      Added DefParser::getLefCell() to lookup master cells in the LEF
    libraries before looking in the Alliance ones (rooted under "LEF"
    library).
* Change: In CRL::LefParser::_pinPostProcess(), when no segment suitable
    for terminal connexion is found, add all of them. This is a quick hack
    and an a correct policy that match all techno must be implemeneted.
* New: In CRL::pyCRL, add a Python wrapper for DefImport.
* New: In CRL/etc/45/ispd18/ added configuration files for the "real"
    technology used by the ISPD18 45nm design benchmarks.
2019-03-29 11:07:55 +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.
2019-03-23 11:05:51 +01:00
Jean-Paul Chaput 5dd235b3cd Adding moc cpps to the link of Cyclop under Qt 5.
* Bug: In CRL::cyclop, on former versions of Qt 5 there was a double
    link of the moc generated modules. This appears to be solved under
    Ubuntu 10.04 LTS, so now we have to add them again explicitly.
2019-03-21 13:27:43 +01:00
Jean-Paul Chaput 94044992ef Pin management implemented for NetBuilderHV.
* Bug: In Katana::Track::expandFreeInterval(), the OutsideElement case was
    not handled correctly, the end index must be increased in that case.
    As a result, this function was returning too short an interval.
      This was affecting the computation of perpandicular free interval
    in DataNegociate::update() for perpandicular fixed but not in a track.
* New: In Anabatic::NetBuilder and NetBuilderVH, now manage GCells with
    one Pin, and up to three globals. Used to put terminals at the
    edge of a block.
* New: In EtesianEngine, now manage placed Pins.
    (done through extractInstanceName())
* Change: In CRL::RoutingGauge::getHorizontalGauge() no longer skip PinOnly
    gauges to find the reference one (same goes for vertical).
2019-03-10 13:25:43 +01:00
Jean-Paul Chaput 0b605000ed Bug fixes in Blif parser (no VHDL enforcement) & GDS driver.
* Bug: In Hurricane::DrawingQuery::drawGo(), forgot to apply translation
    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 f107a68938 Reorganisation of menus in a more clear way. 2019-03-05 23:23:14 +01:00
Jean-Paul Chaput 6ae3a902ee Correct H/K parameters for global routing. New cmos45 symbolic.
* Change: In CRL/etc/cmos/kite.conf, setup correct H/K parameters for
    the Katana global router. Value copied from Knik. They give a
    faster solution.
* New: In CRL/etc/cmos45/, new symbolic settings adapted to FreePDK 45nm.
    Courtesy of N. Shimizu. To be used with NSXLIB.
* New In CRL::System, add "coriolis_top" to the set of pathes available
    to the user.
2019-02-26 20:00:28 +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 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 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 116d927d1e Correct comutation of metricsBdu in GDS driver (courtesy of M. Koefferlein). 2018-07-17 13:36:17 +02:00
Jean-Paul Chaput d99d797a40 Debugged the GDSII driver. Now working with Cadence.
* Bug: In CRL::GdsDriver::GdsStream two bugs :
    1. The tm fields are int but must be casted into uint16_t in BGNLIB
       and BGNSTR.
    2. The mandatory LIBNAME record was missing.
    3. We also force, for now the dbu to be 1000 and the UU to be 1um.
2018-07-16 19:43:44 +02:00
Jean-Paul Chaput 55a29488c9 Correct handling of lambdas & microns in configuration files.
* Bug: In CRL/etc/NODE/VENDOR/Technology.conf, the database must be configured
    as early has possible so the functions ensuring length conversions can
    work correctly (l(v), u(v)). So we can no longer rely on a table to be
    read after the execution of the file. We perform a direct call to the
    helpers.Technology.initTechno() function. And it must be made first
    thing.
      In all tables taking dimensions, we must use one of the converter
    function helpers.l(v), helpers.u(v) or helpers.n(v) so the the value v
    get converted in lambda, microns or nanometer (resp.). Make the
    modifications in all technology.conf and kite.conf files.
* Change: In CRL/coriolisInit.py, remove the technoConfig variable that has
    been replaced by a direct call to helpers.Technology.initTechno().
* Change: In CRL/helpers.Alliance.loadRoutingGaugesTable(), no longer try to
    convert coordinates, they must already be in DbU.
* Change: In CRL/helpers.__init__.py, remove lambdaMode() and micronsMode()
    they could not be made to work as expected. Create l(), u(), n() as
    replacement.
2018-07-16 11:32:40 +02:00
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.
2018-07-16 11:16:51 +02:00
Jean-Paul Chaput 6b29ad0078 In AllianceFramework, no longer try to load ".vhdl" files in ".vst".
* Change: In CRL::ParserMap, no longer recognize the file extensions
    ".vhdl" and ".vhd" which are true VHDL and cannot be parsed by the
    "vst" (Alliance structural subset VHDL) parser.
       This should solve annoying problems for the Makefiles when there
    is both the full VHDL file ".vhdl" and the synthesized one ".vst"
    (note that this problem do not arise when using Yosys/Blif).
2018-06-11 16:49:40 +02:00
Jean-Paul Chaput ea9a1f3710 CRL::Blif parser now able to load both non-Alliance & Alliance design.
* Change: In CRL::Blif, we now can add a list of Hurricane library for
    the parser to look for standart cells. If the library list is *empty*
    we look use the Alliance mechanism, if not, we look *only* in this
    library list. This behavior is implemented in Subckt::createModel(). I
      To add a library, use CRL::Blif::add(Library*).
      This allow to manage symbolic or real mode loading, it may need
    some rework to clarify the interface.
2018-06-08 12:02:49 +02:00
Jean-Paul Chaput c5034a9156 Typo in CMakeLists.txt : AND instead of "and". 2018-06-06 23:22:18 +02:00
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 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 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 1a338f620c Corrections in the Dijkstra global routing (ripup) mechanism.
* Bug: In Anabatic::Dijkstra, the degree of a vertex (the number of neighbors
    belonging to the same net) was miscalculated. This was leading, in the
    materialize step to some feed-through vertexes not being broken.
    Leading in turn to incomplete transformation of the detailed routing.
      Also in _trackback(), the degree of the first vertex we were backtracking
    from was not incremented.
* Bug: In Anabatic::Dijkstra::materialize(), systematically use
    GCell::breakGoThrough() on both source and target. This is needed when
    we are in the ripup phase as both source and target can be go-through.
      This was also leading to incomplete detailed routing transformation.
* Change: In Anabatic::Edge::ripup(), ripup one third of the segments instead
    of thoses exeeding the global length threshold. This way we are sure to
    desaturate an edge. Needs to be further calibrated.
* Change: In Aanabatic::GCell::breakGoThrough(), no longer return NULL.
    Return existing gcontact if any. Break if it is a go-through and create
    a new gcontact in last resort. Maybe rename this function.
* New: In Anabatic::Configuration, new parameters:
    - anabatic.edgeHScaling, to adjust the length of the horizontal edges
        relative to the vertical ones (this is a ratio).
    - anabatic.globalIterations, set the maximum number of ripup passes
        of the global router.
* New: In CRL/etc/*/kite.conf, added new parameters anabatic.edgeHScaling
    and anabatic.globalIterations.
* New: In Katana::GlobalRoute::DigitalDistance, take into account the new
    edgeHScaling factor. Must be used when the capacity of V-edges differs
    greatly for H-edges (case of AMS 350nm c35b4 for instance).
* Bug: In Katana::GlobalRoute::DigitalDistance, the historic cost is
    computed for an edge length of "1". Must be multiplicated by the
    current edge length to have any measurable effect.
      This bug is finally explaining why the ripup was producing the
    same solutions over and over, the historical cost was negligible!
2018-04-16 12:10:48 +02:00
Jean-Paul Chaput cabbab5140 Correct interval capacity computation around zero in RoutingLayerGauge.
* Bug: In CRL::RoutingLayerGauge::divide() & getTrackNumber(), the number
    of traks crossing an edge was wrongly computed for GCells around the
    zero coordinate, this was due to the change in rouding direction
    around zero. It was starting to show for routing gauges with an offset.
      Note: to simplificate the computation of the capacity of an interval,
    all the track over a Cell are computed from (0,0). The Cell abutment
    box has to be choosen relative to that. The tracks positions are fixed
    all over the Cell (or chip if it is one).

    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.

Jean-Paul Chaput 23cb020ed3 Fix in 180/scn6m_deep_09, forgot to setup metal layers mininal spacing.
* Bug: In CRL Core, etc/180/scn6m_deep_09/technology.conf the minimal
    spacing for the metal layers layout were not set, allowing the
    router to place VIAs too close to each others. This was generating
    either DRC errors or short-circuits.

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.

Jean-Paul Chaput 793dbb26b2 Capacity managment by layer in Edges & GCells (plus fixes).
* New: In Anabatic::EdgeCapacity, dedicated object to manage the capacities
    of an edge by layer. This needed now because with real technologies
    layers capacities differs (unlike with symbolic technologies).
      This object is separated to be shared between Edges with identical
    characteristics (direction+interval). Deletion is automatic and
    done through refcounting. All the already allocateds EdgeCapacity
    are kept into a set in the AnabaticEngine (key is (direction,interval)).
* New: In Anabatic::Edge, capacities are stored in a shared EdgeCapacity
    object. The total capacity can be annotated (i.e. decreased).
      EdgeCapacity attribute is created during the materialize() call.
    The capacities are computed at this time.
      The incCapacity() function is renamed in reserveCapacity().
* New: In Anabatic::AnabaticEngine, added attribute _edgeCapacitiesLut
    to store the shared EdgeCapacity.
      Lookup/Creation of an EdgeCapacity is done through _createCapacity().
* Change: In Anabatic::Constants, rename Flags::IllimitedCapacity into
    Flags::InfiniteCapacity. Add Flags::NullCapacity (both for Edges).
* Change: In Anabatic::GCell, implement a by depth (for layer) getCapacity().
    This modification did expose a bug in the density calculation :
    per depth density where divided by the complete density instead of the
    density's depth. This was leading to greatly underestimated densities.
    Thoses underestimations where preventing Dijkstra and layer assignement
    to manage congestion correctly (in fact, it was acting as if there
    never was congestion).
      Also avoid a divide by zero (thus -NAN showing in densities).
* Change: In Anabatic::GCell, rename setEdgeOccupancy() into the more
    accurate forceEdgesCapacities().
      Note for Eric: only the first Edge on each side has it's capacity
    forced. What if there's more than one Edge ?

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.
2018-02-17 20:27:38 +01:00
Jean-Paul Chaput 7bcf47212b Improved management of AutoContactTerminal for VH gauges (real ones).
* New: In Anabatic & Katana, add the new "drag" feature.
    With VH gauges used by real technologies (M1-H, M2-V, M3-H) a new
    routing configuration that was not efficiently handled did appear.
      While the preferred routing direction for metal1 is officially
    horizontal, due to the way the standard cell must be designed,
    their metal1 terminals are still verticals (or punctuals).
      Thus, when connecting to them, we face the case where the metal1
    terminal (RoutingPad) is vertical *and* the metal2 wire is also
    vertical. With that setup, the position of the AutoContactTerminal
    via12 cannot be deduced, it may range all the way over the
    metal1 RoutingPad. What may define it's position is the metal3 the
    metal2 finally connects to. That, is, when we have one horizontal
    (the metal3) and one vertical (the metal1 RoutingPad).
      The intermediate wire of metal2 can be kept to a minimum size
    by "dragging" the via12 close to the via23 when the metal3 wire is
    moved.
* New: In Anabatic & Katana, problem of closely vertically aligneds
    RoutingPads in metal1 is managed first in PreProcess by restricting
    the span of the connecteds metal3 and in _makeDogleg also by restricting
    the span even more tightly (to the RoutingPad itself).
* New: In Anabatic::AutoContactTerminal, add the "drag" support.
    Automatically check if the connecting segment is in the same
    direction as the RoutingPad, if so, sets the "SegDrag" flag.
      The dragging state can be known with the "::canDrag()" predicate.
* New: In Anabatic::AutoHorizontal, add the "drag" support.
    The drag state can be known with the "::isDrag()" predicate.
      In "::_makeDogleg()", when making a dogleg on a dragable segment
    pass the drag state correctly and restrict the perpandicular span
    of the perpandicular to the RoutingPad (though segment user constraints).
    If we make a dogleg on the metal2 is it likely than we cannot go
    straigth out vertically from the RoutingPad, so the new perpandicular
    *is* restricted to the RoutingPad span.
      Idem for AutoVertical.
* New: In Katana::Manipulator, add method "::dragMinimize()" which find a
    hole where to minimize a draggable segment. We finally did not use it,
    but keep it for potential further use.
* New: In Katana::PreProcess, adds a "protectAlignedaccesses()" local
    function to check for vertically aligned metal1 RoutingPads, in that
    case setup user constraints on the metal3 segments so they cannot
    completly cover the other RoutingPad with metal2.
      We also keep a "metal2protect()" function that create a fixed segment
    to lock/protect a RoutingPad. Not used for now.
* New: In Katana::Session, add a RoutingPad locking event mechanism.
    This allows us to request the creation of a locking (fixed segment)
    over a draggable segment. Not used for now.
      Lock events are processeds before all others as they create new
    TrackElements.
* New: In Katana::Track, "::getNextFree()" and "::getPreviousFree()"
    method to find the nearest free interval in a Track after/before a
    position.
* Bug: In Anabatic::AutoHorizontal::getConstraints(), merge with user
    constraints *only* if it's not an empty interval (as we use min/max
    functions). Idem for AutoVertical.
* Bug: In AutoSegments_OnContacts::Locator::isValid(), the boolean test
    must be inverted. Seems it never worked, but we never used it until
    now...

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 3d0431b238 In CRL, update real conf. files. Smarter management of pin in LEF parser.
* Change: In CRL Core, etc/, update the configuration files of real
    technologies. Mostly for FreePDK 45. This work is also done for
    AMS c35b4 (350nm) but in a private (SoC) git repository.
      Added a new parameter 'lefImport.minTerminalwidth' for the
    minimum size (width) of a metal1 terminal in standard cells.
      Corrected bug of the minimum trace level which must be
    initialized to a great value and *not* zero;
* Change: In CRL Core, BlifParser, detect when there is no tie low
    or tie high defined, issue an error (connexion left open) but
    continue.
* New: In CRL::RoutingLayerGauge, new overlad of getTrackPosition()
    with the parameter set of getTrackIndex(). Used to know if a
    terminal is on-grid or not.
* New: In CRL::LefImport, smarter management of metal1 pins. Adds a
    _pinPostProcess() function to select the external components
    among the various shapes. If the gauge is VH, all the pin rectangles
    are translateds into vertical segments (even if the metal1 gauge
    says the tracks are horizontals).
      The _pinPostProcess() function adds as external components of
    a net, only the segments of a sufficent width as given in
    'lefImport.minTerminalWidth' and that are on-grid.

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).

* 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.

    create accessors and mutators.
      Finish virtualising all GCell build methods and transfer them
    into the NetBuilderHV class.
      Build methods now return a boolean to tell if the GCell was
    processed or not, to allow cascading in the "big switch".
      Reorganise the "big switch" in separate sections only partially
    cascading.
      Truly fuse the *big switch* for channel routing and over-the-cells.
      Create a new method "_do_globalSegment()" to delagate the
    drawing of global segments between two GCell to the derived classes.

Jean-Paul Chaput e51ff95337 Support for non-square routing pitch. Allow loading of "foreign" cells.
* New: In CRL Core, AllianceFramework::getCell(), adds a new Catalog::State
    flags to request the loading of a "foreign" cell. That is, a Cell which
    is *not* in the Alliance libraries, but in *any* library starting from
    the root library. This is a temporary hack to allow the Blif parser to
    run.
* New: In CRL Core, RoutingGauge::getHorizontalGauge() and
    RoutingGauge::getVerticalGauge() to avoid relying on either metal names
    or depth to know the vertical and horizontal default routing
    informations. They return the metal layers gauges *closests* to the
    substrate which are likely to have the lesser pitch.
* New: In CRL Core, BlifParser, new configuration parameters:
    "etesian.cell.zero" & "etesian.cell.one" to figure out what are the
    tielow and tiehigh cells (instead of having the ones from sxlib
    hardwired).
* New: In Etesian, add support for non-square routing pitchs, that is,
    the lowest vertical and horizontal pitches are not equal. Needs to
    work with two pitches (H & V) instead of one.
      The Configuration associated class now also provides the
    RoutingGauge (not only the CellGauge).
      Use a new Configuration setting "etesian.feedNames" to set up
    the names of the filler cells. This a string of comma separated
    cell names.
* New: In Anabatic, Session::_getNearestGridPoint(), use the new
    non-square grid scheme.
