Jean-Paul Chaput c86d074f06 Export Contact::setLayer() to the Python interface. 2023-01-14 12:05:51 +01:00
Jean-Paul Chaput 2501688dd1 Add support for layers alias names. Bug in _addPhysicalrule().
* New: In Technology, in order to support symbolic technology on top
    of a real technology using non-generic layer names, it comes in
    handy to be able to define layer alias names. Generic *real*
    layer names could be defined as alias over the technology
    specific ones. Then, we can build the symbolic layers upon
    the generic names (so *that* part of the init code can be
    shared between techs).
       Adds Technology::addLayerAlias()
       The semantic of Technology::getLayer() changes a little, it
     return the techno layer associtated to the name *or* the
     aliased name.
* Bug: In Technology::_addPhysicalRule(), in case of a rule redefinition,
    we were using it's name *after* the deletion of the rule object.
    Nasty crash.
      Improve the error message by giving the name of the conflicting
    rule.
* In CRL/helpers.analogtechno, add an addDevice() function to load
    analogic devices descriptors (copied from the old init system).
* In CRL/ApParser, if an exception is catched, tells in which file and
    line it did occur.
* In Oroshi/dtr.Rules, add a translation step to get the rule names
    from the technology. From generic names to actual technology
    layer names.
       Add some documentation.
* In Oroshi/stack.Stack, get the layers names through dtr.Rules to get
    the layers names translated.

Jean-Paul Chaput 56aa978a9b Added management of Python attributes on DBo.
* New: Isobar::PyAttributesHolder, a PyObject with only a dictionary
    to hold the attributes associated to a DBo.
* New: Isobar::PyHolderProperty, the Property that encapsulate
    PyAttributesholder.
* New: Isobar::PythonAttributes, the extension to simplify the
    management of the PyAttributesholder.
* Change: In PyEntity, now use a dedicated tp_getattro and tp_setattro
    to delegate the Python attribute access towars the PyAttributesholder.
* New: In hurricane/doc & documentation, update docs regarding Python
    attributes managment.
2022-08-13 17:46:47 +02:00
Jean-Paul Chaput cd60032d9c Added direct management of macro blocks I/O pins in METAL2 & METAL3.
The decoupling of the cell gauge and the routing gauge implies that
the METAL2 & METAL3 terminals of macro blocks cannot be aligned on
the routing tracks anymore. That is, an horizontal METAL2 terminal
will not be on a track axis, but offgrid, so we no longer can use
a METAL2 horizontal segment to connect to it. Making an adjustement
between the offgrid terminal and the on-grid segment has proven
too complex and generating difficult configuration for the router.
Moreover, METLA2 terminal could be fully inside a METAL2 blockage.
So now, when the gauges are decoupled, we connect the METAL2 and
METAL3 the same way we do for METAL1: *from above* in the perpandicular
direction and using a *sliding* VIA. We assume that those kind of
terminals in upper metals are quite long.

* New: In Hurricane::Rectilinear, export the isNonRectangle() method
    to the Python interface.
* New: In CRL::RoutingGauge, add function isSuperPitched() with the
    associated boolean attribute. Set to true when each pitch of
    each layer is independant (not low fractional multiples).
* New: In AnabaticEngine, add the ability to temporarily disable the
    canonize() operation (mainly used in dogleg creation).
* New: In AutoSegment::canonize(), do nothing if the operation is
    disabled by AnabaticEngine.
* Bug: In Session::_revalidateTopology(), disable the canonization
    during the topology updating of a net. Too early canonization
    was occuring in makeDogleg() leading to incoherencies when
    performing the later canonization stage over the complete net.
    Mostly occured in the initial build stage of the net.
* New: In GCell, add function postGlobalAnnotate(), if a layer
    is fully blocked (above 0.9), typically, under a blockage,
    add a further capacity decrease of 2 on the edges. So we may
    handle a modicum of doglegs.
* Bug; In GCell::addBlockage(), removeContact(), removeHSegment()
    and removeVSegment(), forgot to set the Invalidated flag.
    This may have lead to innacurate densities.
* Change: In GCell::updateDensity(), more complex setting of the
    GoStraight flag. This flag is now set if we don't have two
    *contiguous* below 60% of density. We need free contiguous
    layers to make doglegs.
* New: In NetBuilder, now manage a current state flag along
    with the state flag of the *source* GCell. This flag is used
    to tell if the GCell needs it's *global* routing to be done
    using the upper layers (METAL4 & METAL5) instead of the
    lower ones.
* New: In NetBuilder::setStartHook(), set the state flag of the
    GCell to ToUpperRouting when processing a global routing
    articulation and one of the base layer is obstructed
    above 0.9.
      In GCell with terminals, also set ToUpperRouting when there
    are some in METAL2 / METAL3 and the gauge is not super-pitched.
* New: In NetBuilder, function isInsideBlockage(), to check if a
    terminal is completely or partially enclosed in a blockage.
* Change: In NetBuilderHV::doRp_AutoContact(), remove support for
    trying to put on grid misaligned METAL2/METAL3.
      Instead systematically access them from above.
      Do not cover with fixed protection terminals that are already
    enclosed in blockages.
* Bug: In NetBuilderHV::doRp_AutoContact(), always add the terminal
    contact in the requested GCell and not the target/source one,
    in case the terminal span several GCells.
* Change: In NetBuilderHV::doRp_Access(), create the local wiring
    according to the RoutingPad layer.
* Change: In NetBuilderHV::_do_xG(), _do_2G(),
    create the global wiring in upper layers, according to the
    ToUpperRouting flag.
* Change: In NetBuilderHV::_do_xG_xM3(), now delegate to
    _do_xG_xM3_baseRouting() and _do_xG_xM3_upperRouting() if the
    density at terminal level is above 0.5.
* New: NetBuilderHV::_do_xG_xM3_baseRouting() and
    _do_xG_xM3_upperRouting() separated function to manage the
    local routing.
* Change: In NetBuilder::_do_globalSegment(), if the currently
    processed GCell or it's source is in ToUpperRouting mode,
    move up the global segment. Do *not* use the moveUp() function
    which would create doglegs unwanted at this stage.
* New: In KatanaEngine::annotateGlobalGraph(), call postGlobalAnnotate()
    on the GCell after the blockages have been taken into accound to
    add the penalty.
* Bug: In Track::getPrevious(), correctly manage the 0 value for the
    index argument. Strange it didn't show earlier.
      Same goes for Track::expandFreeInterval().

Jean-Paul Chaput be598c9b96 Update the Python wrapping of Hurricane::Entity.

Jean-Paul Chaput df972b7250 Add Diode/Feed flags in Cell. Correct computation of Instance count.
WARNING: We are partially duplicating the informations pertaining
         to the Alliance catalog (stored in the Catalog property)
	 directly into the Cell. This is needed for Flexlib which
	 is not using the Alliance loading mechanim. Ideally the
	 Catalog information should be moved into the Cell.

* New: In Cell, add new state flags Diode, PowerFeed (in addition to
    Pad & Feed).
      Export flags setter/getter to Python. For Flexlib usage.
* Change: In AllianceFramework::getInstancesCount(), correctly skip
    Diode & Feeds based on Cell flags. Those flags must correctly
    be set in the various Flexlib_fix.py scripts.
2021-11-28 19:03:02 +01:00
Jean-Paul Chaput 02777e127e Migration towards Python3, first stage: still based on C-Macros.
* New: Python/C++ API level:
  * Write a new C++/template wrapper to get rid of boost::python
  * The int & long Python type are now merged. So a C/C++ level,
    it became "PyLong_X" (remove "PyInt_X") and at Python code
    level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
  * Configuration is now integrated as a Hurricane component,
    makes use of the new C++/template wrapper.
  * vlsisapd is now defunct. Keep it in the source for now as
    some remaining non essential code may have to be ported in
    the future.
* Note: Python code (copy of the migration howto):
  * New print function syntax print().
  * Changed "dict.has_key(k)" for "k" in dict.
  * Changed "except Exception, e" for "except Exception as e".
  * The division "/" is now the floating point division, even if
    both operand are integers. So 3/2 now gives 1.5 and no longer 1.
    The integer division is now "//" : 1 = 3//2. So have to carefully
    review the code to update. Most of the time we want to use "//".
    We must never change to float for long that, in fact, represents
    DbU (exposed as Python int type).
  * execfile() must be replaced by exec(open("file").read()).
  * iter().__next__() becomes iter(x).__next__().
  * __getslice__() has been removed, integrated to __getitem__().
  * The formating used for str(type(o)) has changed, so In Stratus,
    have to update them ("<class 'MyClass'>" instead of "MyClass").
  * the "types" module no longer supply values for default types
    like str (types.StringType) or list (types.StringType).
    Must use "isinstance()" where they were occuring.
  * Remove the 'L' to indicate "long integer" (like "12L"), now
    all Python integer are long.
* Change in bootstrap:
  * Ported Coriolis builder (ccb) to Python3.
  * Ported Coriolis socInstaller.py to Python3.
  * Note: In PyQt4+Python3, QVariant no longer exists. Use None or
    directly convert using the python syntax: bool(x), int(x), ...
    By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
  * In order to compile user's must upgrade to my own rebuild of
    PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
    buffer of the H-Tree to the original signal (mainly: top clock).
      Strangely, it was only done when working in full chip mode.
2021-09-19 19:41:24 +02:00
Jean-Paul Chaput 205a6877db More generic H-Tree support to accomodate the LS180 PLL internal clock.
The H-Tree support is now allowed for any net, not only the clocks and
not only top-level nets. This allow to better management of the LS180
internal clock signal.

* New: In Cell::flattenNets(Instance*,set<string>,uint64_t) new overload
    of the function to allow the user to select nets that will *not*
    be flattened. This makes the NoClockFlatten flag effectively obsolete,
    we keep it for backward compatibility.
      The net names can be of non top level ones. In that case, they must
    use the name an HyperNet will get (the Occurrence name). For example:
         "instance1.instance2.deep_net_name".
* New: In PyCell, update the wrapper for the new parameter of flattenNets(),
    new utility function pyListToStringSet() to translate a Python list into
    a C++ set of names.
* New: In EtesianEngine, add support for a list of nets to be excluded
    from the flattening procedure. Those excluded nets will also be
    excludeds from the Coloquinte nets *and* HFNS synthesis, as they
    are likely to be manageds by a H-Tree.
* Change: In AnabaticEngine::_loadGrByNet(), now also skip nets that are
    flagged as manually detailed route.
* New: In AnabaticEngine::antennaProtect(), do not try to insert diodes
    on nets that are already fixed or detaled route. This replace the
    clock exclusion.
* New: In cumulus/plugins.{block,htree,chip}, replace the concept
    of clock-tree by the more generic H-Tree. That is, we can ask the P&R
    to create H-Tree on any net of the design, not only the ones matcheds
    as clock. The net does not even need to be top-level.
      This is to manage the PLL internal clock generated by the PLL in
    the LS180 chip.
      Start to change all reference to "clock" into "H-Tree".
* Bug: In cumulus/plugins.chip.powerplanes.Builder._connectHTree(),
    there was an inversion of the H & V routing gauges to compute the
    track into which put the H-Tree center to corona edge wiring.
      This was causing tracks to be used twice, seen in the ao68000 test
    bench.

Jean-Paul Chaput 90300eb651 Small typo in Cell::getComponentsUnder() Python wrapper. 2021-05-22 14:54:36 +02:00
Jean-Paul Chaput 11390867f1 A more compact string representation for Hurricane::Path. 2021-03-15 23:45:33 +01:00
Jean-Paul Chaput a6492f6edc Allow Hurricane::Query to stop on master cells with designated flags.
* New: In Query & QueryStack, add a new stop criterion "stopCellFlags"
    based on the flags of the instances master cell. The instance will
    still be processed, but not it's childs. Typically used to stop
    exploring on "AbstractedSupply" cells.
      Exported in the Python interface.
* New: In Cell::Flags, new value "AbstractedSupply" to mark Cells from
    which an abstract has been built for supplies & blockages. But *not*
    for common nets. Helps reduce the recursion through the hierarchy
    when building supply line in FlattenPower.
      Export setter/getter in the Python interface.
* New: In Instance, add a "PruneMaster" filter to stop hierarchical
    exploration on instances which master cells have at least one of
    the given flags set.
* Change: In NetExternalcomponents::isInternal(), use "const Component*"
    instead of "Component*".
* Bug: In Cell::Flags, the NoFlags must be *zero*, not *one*! And we
    can reclaim that bit for future use.
* Cleanup: In Hurricane::Cell, remove changeQuadTree() related methods.
    Fusing various Cell's QuadTree is not a viable idea.
* Cleanup: In Hurricane::Instance, remove no longer used "_flags"
    attributes.
2021-03-02 12:17:13 +01:00

Jean-Paul Chaput b0ae6be652 Export Cell::flattenNets() & revlevant Cell flags. 2020-12-27 12:21:14 +01:00
Jean-Paul Chaput f5ee37d2e6 Manage minimum area for VIAs in the P&R.
* New: In Hurricane::Layer, add support for a minimal area (given in
    microns). Exported in the Python interface.
* New: In Anabatic::AutoSegment::bloatStackedStrap(), method to
    enlarge too small vertically stacked VIAs. For now just create
    a square ensuring the minimal area. Potentially cause DRC error in
    some cases so needs to be refined.
* New: In Anabatic::_gutAnabatic(), check for too little stacked VIAs
    and display a report.
2020-11-16 00:55:49 +01:00
Jean-Paul Chaput a4eb811bcb Exported Layer::getTopEnclosure() in Python interface. 2020-11-14 18:51:41 +01:00
Jean-Paul Chaput 79f3350eba More explicit error message in Cell.getNet() Python wrapper. 2020-10-14 14:58:32 +02:00
Jean-Paul Chaput 8f0a8e5a3a Added support for loading user defined global routing in Anabatic.
* New: In Hurricane::NetRoutingProperty, add and change the meaning
    of the following flags:
      - ManualGlobalRoute : now means that a global routing *trunk*
        is present, made of "gmetalh", "gmetalv" & "gcontact".
      - Manualdetailroute : added, get the former meaning of
        ManualGlobalRoute, that is, the detailed routing is
	already present for this net, but can be changed by the
	detailed router. Implies that it respect the Terminal,
	HTee & VTee structuration.
* New: Add Anabatic::Diskstra::loadFixedGlobal(), to account
    a manually global net into the edges capacities.
* New: In Anabatic::Edges::ripup(), exclude manually global routed
    segments from the ripup. Change the segment sorting function
    so that thoses segments are put in head of list (considered
    as "smaller").
* Change: In AnabaticEngine::setupPreRouteds(), now detect manual
    global routed and manual detail routed signals, and tag them
    accordingly.
* New: In AnabaticEngine::Configuration & Session, add proxies
    for the global routing layers ("gmetalh", "gmetalv", "gcontact").
* New: In Anabatic::Constants, add flags for global fixed and
    detail routed nets.
* Change: In KatanaEngine::updateEstimateDensity(), now use int64_t
    for flute coordinates.
* New: Add CRL::RoutingGauge::hasLayer(), to know if a layer is
    managed by the gauge (comparison by mask).

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

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

Jean-Paul Chaput f2a60768ca Export Entity::getId() to the Python interface. 2020-06-06 12:13:57 +02:00
Jean-Paul Chaput a50b6ce317 More PEP8 compliant Python code. Start rewrite Python/C++ wrappers.
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
    Move towards more Python PEP8 compliance:
      * All indentations sets to 4 spaces (in progress).
      * In plugins, remove messages about software collections
        and RHEL (too many case could wrongly lead to that).
	Instead systematically uses "helpers.io.catch()".
      * Put in lowercases all modules names. Note that C++ exported
        modules *keep* their Capitalized names (to preserve the
	identity with the C++ namespace).
      * When making import, use full path.
      * Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
    the one ending in ".conf". Keep those who have not been ported
    to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
    C preprocessor macros by C++ templates. Applied first to configuration
    from VLSISAPD.
      This is unfinished business, just a limited demonstrator for now.
      It is installed as a separate Python library "Cfg2" which do not
    interact with the rest of Coriiolis.
      The end goal is to fully remove boost and merge VLSISAPD useful
    components directly inside Hurricane.

Jean-Paul Chaput 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 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.

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 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 1b444d8f49 In cumulus/Core2Chip.py forgot a parameter to an error message call. 2019-07-31 19:16:40 +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 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.
