Jean-Paul Chaput 864b031b6a Disable backtrace generation in Hurricane::Error constructor.
* Change: In Hurricane::Backtrace constructor, add a boolean parameter
    to enable/disable the actual backtrace generation.
* Change: In Hurricane::Error constructor, disable by default the
    backtrace generation. The backtrace is useful when the Error is
    thrown, and the program therefore stopped. But in many case we
    just issue the error message on the console and try to continue.
    But if the backtrace is enabled, it terribly slow down the
    program.
      Have to think about an clean way to re-enable the trace only
    when the exception is thrown.

Jean-Paul Chaput 24d8fe5957 Cleaner support for real technologies (Hurricane, CRL Core configuration).
* Change: In Hurricane::Technology, in all the layer connexity methods
    (getLayers(), getMetalAbove(), getCutAbove(), getViaBetween(), ...)
    the "useWorking" parameter is replaced by a more accurate "useSymbolic".
      BEHAVIOR CHANGE: formerly, if a symbolic layer was requested, and
    none was found, NULL was returned. Now, if the symbolic layer is not
    found, we try to return the associated real one (same layer mask,
    but not flagged as symbolic, and usually with a lowercase name).
      All thoses changes have been propagated to Python bindings.
* Change: In Hurricane::BasicLayer and derived classes, rename the
    "isWorking" attribute into "isSymbolic" (to match the technology
    renaming).
* Change: In Hurricane::Cell::flattenNets(), ignore power, ground and
    blockage nets for the flatten.
* Change: In CRL Core, in coriolisInit.py and Technology.py helpers,
    rename the tables describing the technology as follow:
      - symbolicLayersTable --> compositeLayersTable
      - workingLayersTable  --> symbolicLayersTable
      - symbolicRulesTable  --> layersExtensionsTable
    This is to give the table names a more clearer semantic after
    merging real technologies configurations (testbench AMS c35b4).
      In particular, we need to define a composite layer for the
    real VIAs, and not only the symbolic ones. And with correct
    enclosures expressed in real dimensions (microns).

Jean-Paul Chaput 24d5e9f172 The min debug level has to be high (10000) and not zero.
* Bug: In Hurricane the ::tstream class must be initialized with a
    minLevel of 10000 instead of zero, as the minLevel go *towards*
    zero as the debug slice [min:max[ is expanded by DebugSession.
      This default value must be repeated in the CRL::System CTOR
    and in the coriolis2/etc/commons/misc.conf.
* Bug: In Hurricane::IntrusiveSet, uses "tsetw(n)" dedicated cdebug
    stream manipulator instead of the STL one.

Jean-Paul Chaput a75c77626c More meaningful names in Anabatic::NetBuilder. Use of isTwoMetals(). 2017-12-19 00:28:38 +01:00
Jean-Paul Chaput f87bcf717c Complete the modularization of the detail routing converter.
* New: In Anabatic::NetBuilder, set all the attributes as private and
    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 4c57b0651a Modularize the global to detail routing converter.
* New: In Anabatic, rename GCellTopology to NetBuilder, expose  the class
    (no longer in a local namespace).
      NetBuilder become a base class performing the walkthrough the Net
    tree. Derived class are tasked to build routing for specific gauge.
      NetBuilderHV is created to manage all gauge with metal2 horizontal
    and metal3 vertical.
      In our terminolgy we consider that the first routing metal is
    metal2. Metal1 is used inside the standard cells.

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.

Jean-Paul Chaput 2b3b847162 New LEF importer for real technologies.
* New: In CRL Core, added LEF importer for real technologies. This is
    still a work in progress. Exported in Python interface.
* Bug: In CRL Core, CellGauge::getRecord() correctly display DbU
    attributes.
* Change: In Unicorn, mofificate ImportCell and ImportCellDialog to
    support the LEF importer. Add a template layer so we can work with
    loaders returning Cell* or Library*.
* Change: In Unicorn::UnicornGui::getCellFromDb(), in addition to the
    Alliance loader, uses the DataBase::getCell() too (for Cells that
    are *not* in Alliance).
2017-11-17 11:48:20 +01:00
Jean-Paul Chaput 51b3a11739 In Kite & Katana, segments may have been moved outside terminals.
* Bug: In Kite::NegociateWidow and Katana::NegociateWindow, when creating
    the TrackSegment from the AutoSegment, we put it on the nearest track
    from its current position. But it may happens that the nearest track
    is outside the terminal constraint interval (in the case of "nsxlib").
    Add the terminal constraint interval check.
      This was not affecting the routing result because the segment was
    put inside the right interval afterwards. It was only generating
    disgraceful transient error messages...

Jean-Paul Chaput bc1c7838d1 Reorganisation of technology configuration files.
* Change: In CRL Core, in coriolis2/etc the file an directory structure
    describing the technonolies is modified.
      Before, one technology was split in two: the symbolic part that
    may be shared across multiple real technology and the real technology
    itself. To configure this we needed in ".coriolis2/techno.py" two
    variables:
      * symbolicTechnology.
      * realTechnology.
      After, we duplicate the symbolic technology in each real ones, so
    to configure we only have to refer to one technology with the
    variable:
      * technology.
      Pure sympolic technologies are still availables, associated with
    a dummy real one.
      We provides:
      * 180/scn6m_deep_09  for MOSIS 180nm
      * 45/freepdk_45      for FreePDK 45nm (work in progress).
      * symbolic/cmos      for classical Alliance symbolic.
* Change: In CRL Core python/helpers, SymbolicTechnology.py and
    RealTechnology.py are now grouped under Technology.py.

Jean-Paul Chaput bed79c0156 New DataBase::getCell() and bug in Technology::getNthMetal().
* New: Hurricane::DataBase::getCell() method to search a cell through
    all the libraries of *all* the frameworks, not just Alliance.
    Also exported in Python interface.
* Bug: In Technology::getNthMetal() the function was not returning the
    right metal, there was an offset of one. And when the offset was
    0, no metal was even returned. Same fix goes for getNthCut().
      The fault was in Mask<>::nthbit().
* Change: In Hurricane::CellWidget, the initial window size is too tiny.
    Increase the size from 250 to 500 pixels.

Jean-Paul Chaput 4e8ac63408 In CRL Core Python helpers, new showPythonTrace().
* New: In CRL Core Python helpers, add a "showPythonTrace()" function to
    custom display the Python stack trace in case of exception. It ha
    been made to look like a gdb trace.
* In Unicorn, cgt.py, use showPythonTrace().

Jean-Paul Chaput 141cb6e7c2 In Occurrence_Contains(), accept everything when _instance is NULL.
* Bug: In Hurricane::Occurrence_Contains(), when the Instance to match
    is set to NULL, that means we have to accept *all* instances instead
    of rejecting them all. This bug was making the Cell::flattenedNets()
    to do nothing in digital mode.

    project. Rewrite the Makefiles into CMakeLists.txt, build only
    the C++ version. Create an entry for the LEF/DEF doc in the

Jean-Paul Chaput 4d6b06d368 Update documentation to build on Debian 9.2 (stretch).
* Change: In documentation/CMakeLists.txt, for add_custom_targets(),
    add_dependencies() no longer allow to give files (only others
    *target* in the sense of cmake). We must use the DEPENDS option
    of add_custom_target().
* Change: In documentation/UsersGuide, it seems that docutils no longer
    handle correctly '$' and/or '_' in verbatim in the LaTeX backend.
    (i.e. they are *not* escaped, resulting in math mode errors).
    Remove those characters as we can use others...
* Commit a snaphot of the current documentation.

Jean-Paul Chaput eae5d6bf83 Added support for 2-Metal block routing in Anabatic & Katana.
* New: In AnabaticEngine::invalidateRoutingPads() this method is a temporary
    workaround for a Hurricane problems. When an instance is moved, the
    RoutingPads that use it must be moved accordingly, but they are not
    invalidated so they stay in the wrong QuadTree.
      New method ::_resizeMatrix() to be called when the associated Cell
    is resized.
* Bug: In AutoHorizontal::getConstraints() and AutoVertical::getConstraints(),
    the *target* constraints where never merged.
* Change: In AutoHorizontal::getCells() and AutoVertical::getGCells(),
    now return a boolean to tell if it was ok (must not encounter a NULL
    GCell while progessing from source to target).
* New: In Anabatic::Configuration and Anabatic:Session, create new methods:
     - getDHorizontalLayer()
     - getDhorizontalDepth()
     - getDHorizontalWidth()
     - getDHorizontalPitch()
     And so on for Vertical and Contact.
       They supply depth-independant informations about the H/V layers to
     build the initial detailed routing.
        The AutoSegment::create() methods have been modificated accordingly.
* New: In Anabatic::GCell, add two new types "StdCellRow" and "ChannelRow"
    for implementing 2-Metal blocks.
      Rename the GCell::setXY() method in GCell::setSouthWestCorner(),
    move the contents of GCell::updateContactsPosition() into it and
    suppress it.
      WARNING: In case of a GCell shrink this may cause problems. But for
    now we only expand...
      New method GCell::getNetCount() to count the number of Net going
    though the GCell.
* Change: In Anabatic::Edge, add specific support for capacity of 2-Metal
    routing channels.
* Change: In Anabatic::Dijsktra various methods, replace the "gcell->isMatrix()"
    calls by "not gcell->isAnalog()". Add more check so that the methods
    pertaining to the analog routing (GRData) are not called in digital
    mode.
* New: In Anabatic::Dijkstra::materialize(), add support for 2-Metal specific
    cases. That is, always break in case of vertical pass-through or
    U-turn. The global routing must always be broken in H-Channel.
* New: In Anabatic::GCell & Anabatic::Edge, make use of the Session mechanism
    to ensure the revalidation. The "::revalidate()" method is then moved
    as "::materialize()" (overload of Go) and "::_invalidate()" becomes
    "::invalidate()"
* Change: In LoadGlobalRouting, cosmetic rename of SortHkByX in SortHookByX.
* New: In GCellTopology, added support for building 2-Metal topologies.
    * ForkStack is now an object attribute as many methods do need it.
    * To push segments/hook on the stack, a new method "push()" is
      available. Perform NULL and fromHook checking. Can also setup
      _southWestContact or _northEastContact if it is the "from" edge.
    * N/S/E/W edges are now vector as in digital channel mode there
      can be more than one.
    * Added build topological build methods:
      - doRp_2m_Access() RoutingPad stem access.
      - _do_2m_1G_1M1() North or south access.
      - _do_2m_2G_1M1() North AND south access.
      - _do_2m_xG() H-Channel routing.
* New: In Anabatic::Matrix, new ::resize() function, as Cell can be resizeds.
* New: In Anabatic::Vertex, new static method ::getValueString() for a
    friendly text rendering.
* New: In Katana::DigitalDistance, support for channel routing.
* Change: In KatanaEngine::digitalSetup() and KatanaEngine::runGlobalrouter(),
    for channel routing, calls to setupPowerRails() and
    protectRoutingPads() must be called after the core block has
    been fully dimensionned.
      ::runGlobalrouter() contains the code tasked with the grid creation
    and channel sizing.
* New: In KatanaEngine: Added support for core block, for 2-Metal routing.
    May be expanded for over-the-cell routing in the future.
      Added methods :
      - isDigitalMode()
      - isAnalogMode()
      - isMixedMode()
      - isChannelMode()
      - getBlock() / addBlock()
      - setupChannelMode()
      - createChannel()
* New: In Katana, new class Block to manage core blocks and perform
    channel routing.
* New: In Katana::Session, new convenience method "isOpen()".
2017-08-18 23:56:23 +02:00
Jean-Paul Chaput 809a91c9c1 Added Routing Gauge for 2-Metal technologies only.
* New: In CRL Core, etc/cmos/kite.conf new routing gauge "sxlib-2M" for
    two metals only technologies.
* New: In CRL Core, python/helpers/kite.py, new parameter to set the
    routing gauge to be used: "kite.routingGauge" (default: "sxlib").
* Change: In CRL/AllianceFramework.cpp, forgot to put the Cell gauges
    and RoutingGauges in the object Records (Inspector).
* New: In pyCRL/PyAllianceFramework.cpp, export the setRoutingGauge()
    function.
2017-08-18 18:16:43 +02:00
Jean-Paul Chaput 2127fa916b Inspector support for map<> with default sort.

Jean-Paul Chaput cafced2bf8 Katana manage wide wires, and they can also be symmetric.
* New: In Anabatic::AutoContact and the derived classes, manages wide
    wires. The contact self dimension itself according to the segments
    it is connected to. Special case for the AutoContactTerminal which
    also read the size of the component it is anchored upon.
      New refresh method "updateSize()" and flag CntInvalidatedWidth.
    to compute the size.
      In AutoContactTerminal, compute the constraint box according to
    the width of the segment.
* New: In Anabatic::AutoSegment, flags are now implemented as "static const"
    attributes of the class. The flags are stored into a uint64_t as
    they are more than 32.
      Added new flag "SegWide" and associated predicates.
* Change: In GCellTopology::_doHChannel() and GCellTopology::_doVChannel(),
    uses the simpler overload of AutoSegment::create() in order to detect
    the wire width automatically.
* New: In Katana::Manipulator, split insertToTrack() and forceToTrack()
    into a one-track method and a segment level method that iterate over
    the track span of the segment.
* New: In Katana::SegmentFsm, for each cost in the table, now allow access
    to a specific track. So the base functions have now two parameters:
    "icost" and "itrack" (has a cost can have multiple tracks in the case
    of wide segments).
* Change: In Katana::TrackElement, remove the index of the element inside
    it's track, as for a wide segment it will not be meaningful for the
    non-base track. This means that we have to use the Track::find()
    method each time instead.
      Remove the wide flag, as it is a duplicate of the one in AutoSegment.
      Added a getTrackCount() method to tell the number of track the
    segment is inserted into. Needed in the Track destroy step to delete
    a segment only when the last track that refers it is destroyed.
      Added getSymmetricAxis() to correct the computation of the symmetric
    base track in case of wide segment as the base track is not centered
    but the the leftmost one.
* Change: In Track::insert() insert wide segments in their whole track span.
* Change: In TrackCost, create an array of costs according to the segment
    track span.
* Change: In TrackSegment::create(), now activate the factory and create
    wide segments.
* Bug: In Katana::AutoSegments_Perpandicular, correct the debug indentation
    problem (ever shifting to the right).
