Jean-Paul Chaput d0d0e3aa3d Fixing the PyAttributesHolder type definition, again. 2022-08-14 18:28:34 +02:00
Jean-Paul Chaput bdd78ce44a Right preprocess condition in PythonAttribues for old GCC 2022-08-14 18:14:35 +02:00
Jean-Paul Chaput c0b4a73f9e Alternate PyTypeObject inititalization in PythonAttributes for old GCC. 2022-08-14 13:05:35 +02:00
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.

Jean-Paul Chaput 34a3ae327c Revert horizontalAdvance() to width() so it build on old Qt5 versions. 2022-07-14 15:19:24 +02:00
Jean-Paul Chaput f453dbc6f9 Correct the selection bug in Net mode in CellWidget.
In SelectorCriterion & SelectorCriterions, when selecting a Net occurrence,
we where storing the Net only. This was fine if the Net was belonging to
the Cell's top level. But when it was an occurrence of a non-top level
net, this was creating the elusive incoherent Occurrence problem.
Now we truly store the occurrence of the Net, to be accurate, the root
of the HyperNet.

* Change: In SelectorCriterions::add(), the Net* argument is replaced
    by a Occurrence of Net. Must be an HyperNet root occurrence.
      Same goes for SelectorCriterions::remove().
* Change: In CellWidget::select(), when called with a Net occurrence,
    select the whole HyperNet components.
* Change: In NetSelectorCriterion, now use a Net occurrence instead
    of directly a Net. Must be an HyperNet root net occurrence.

Jean-Paul Chaput bbea20b4f6 Correct, again, the problem of PyLayoutGenerator in Python 3.
* Bug: In PyLayoutGenerator, in the method definition of setVerboselevel(),
    the error was not METH_STATIC but the lack of METH_VARARGS flag.
2022-06-05 20:35:39 +02:00
Jean-Paul Chaput 33e148440c Correct a compliance problem with Python > 3.8 of METH_STATIC.
* Change: In PyLayoutGenerator, in the method definition of the class,
    replace the METH_STATIC flag by METH_CLASS for setVerboseLevel().
      There may be more of it elsewere, but as they didn't seem to
    have been triggered, we will see as it happens.

Jean-Paul Chaput 2efae3507e Remove unconnected part of the nets after HFNS.
This was the reason why we, sometimes got "UNCONNECTED" errors in the
VHDL PORT MAP statements. This was the remnants of the originally
connected driver.

* Bug: In Etesian::BufferTree, as the root driver is disconnected from
    all the sinks, but the top tree buffer, we may end up with
    unconnected signal on instances that were using it.
      So now, call BufferTree::rcleaupNet() to remove the Net in
    the Cell that where used to "transmit" the original driver.
* Bug: In Etesian::BufferTree, no longer use a _isDeepNet attribute
    guessed from the occurrences pathes of the RoutingPad, but
    trust the Net::isDeepNet() method.
2022-05-25 17:09:00 +02:00
Jean-Paul Chaput d3b7251eac NetRoutingExtension::get() failsafe when net is NULL. 2022-05-12 17:53:21 +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().
2022-04-27 21:56:41 +02:00
Jean-Paul Chaput fd624f03b6 Forgot emiting "layoutAbouttobechanged" in NetlistModel::setCell().
* Bug: In NetlistModel::setCell() template, forgot to send the
    "layoutAboutToBeChanged" signal before disconnecting the
    netlist datas. This seemed to go unnoticed until ported
    under Qt5. Was generating strange random core dump when
    running the engines with a net kept selected. Disgraceful
    crash during demos...
2022-01-26 19:41:39 +01:00
Jean-Paul Chaput 7f936367f8 Fix deletion bug in Selector::_preDestroy().
* Bug: In Selector::_preDestroy(), *do not* iterate over the _cellWidgets
    map as we destroy it's elements! We end up in destroyed ones...
    Instead destroy the first one until the map is empty.
2022-01-26 19:34:31 +01:00
Jean-Paul Chaput a5d92ecc29 Beautification, display "boundaries" below everything else.
* Change: In CellWidget::_redraw(), the boundaries, that is, instances
    abutment boxes where drawn *after* everything else, so they where
    hiding more interesting informations (especially at low zoom level)
    like routing wires.
      Now draw them *first* so they are *below*.
2022-01-26 19:31:01 +01:00
Jean-Paul Chaput 6210d312fe Correct the image snaphot generation (CellImage).
* Change: In CellImage::setScreenCellWidget, fully copy the display
    settings from the reference widget (not just part of them).
* Bug: In CellImage::toImage(), if the abutment box of the displayed
    cell is not *fully* includer in the viewer area, do *not* try to
    reframe it. The reframe() method seems to be buggy, works OK
    just without calling it.

Jean-Paul Chaput 0d7deafe81 Remove mistakenly commited backup file. 2022-01-01 17:15:41 +01:00
Jean-Paul Chaput 581f557aef Fix: The SelectionPopup widget was deleted after first use.
* Bug: In Viewer::SelectionPopup(), the window attribute
   Qt::WA_DeleteOnClose was *not* cleared. So the window was deleted
   after first use while it was though staying allocated.
     Again, generating weird crashes.
     Took the occasion to slightly redesign the behavior to select
   and highlight individual components.
2022-01-01 16:47:09 +01:00
Jean-Paul Chaput 0c54d109cc Fix: Do not return transient string in PyTypeManager.
* Bug: In Isobar3::PyTypeManager, the accessors _getCppTypeName() and
    _getPyTypeName() where returning string *by value*, hence, short
    lived copies.
      But, in _setupPyType() and _addToModule(), as we interface with
    the Python/C API, we extract the c_str(). Which where removed as
    we used temporary objects. Leading to memory corruption and weird
    crashes.
      Now returns "const string&" so the c_str() stays allocated.
2022-01-01 16:46:41 +01:00
Jean-Paul Chaput 9aaaf33e6e Manage more interrupt signals in CRL::System::_trapSig(). Display value. 2022-01-01 16:46:15 +01:00
Jean-Paul Chaput 5f8a0a944c Display bug for non-rectangular components in DrawinQuery::drawGo().
* Bug: In CellWidget::DrawingQuery::drawGo(), the display condition was
    wrong, it was requiring *both* width & height to be above the display
    threshold. Either one is sufficient to activate the display.
      Was causing the selective diseapearance of gates at low zoom level
    and printed version.
* Change: In CellPrinter, force the display threshold to one pixel in it's
    internal CellWidget used for printing.

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.

      protected configuration. They are using the non-NDA one. No harm
      in that, just need to be known...
2021-11-26 11:32:33 +01:00
Jean-Paul Chaput 966a25181f Optimize Cell::getDeeNet() to fix the slow-down in PowerRails.
* New: In DeepNet, add an DeepNet::Uplink property on the HyperNet
    root net Occurrence so we have a direct two-way link between
    the top (flattened net) and the root of the HyperNet.
      Down link is ensured by the Occurrence, up link by the Uplink
    property.
* Change: In Cell::getDeepNet(), now use the DeepNet Uplink property
    instead of looping over *all* top nets. This was the cause of the
    terrific slow down in PowerRails, especially on flatteneds designs.
2021-11-25 10:49:45 +01:00
Jean-Paul Chaput 10bd5510da Fix library linking problem for gcc 9 and above (Ubuntu 20/Debian 11).
* Bug: In all CMakeLists.txt, it seems I was doing a worng use of
    target_link_library(). No longer add dependencies to the C++ base
    library but instead either to the Python associated module or
    to the final binaries. This was inderectly causing the linking
    problem related to Python (which was a misdirection).
* Bug: Typo in FindLibexecinfo.cmake, do not use FindLib[E]xecinfo.
* Change: In CRL/ccore/CMakeLists.txt, activate SKIP_AUTOMOC on
    bison/flex generated files.
* Bug: In viewer/PyHApplication, do not delete the C++ object in
    the Python destroy method.
2021-11-22 00:05:48 +01:00
Jean-Paul Chaput 302accfbb1 Update documentation (by mistake, nothing new). 2021-11-21 23:40:40 +01:00
Jean-Paul Chaput fcf6ec97c3 More fixes for the selection & inspector mechanisms.
* Bug: In Common.h, makes the INSPECTOR_PV_SUPPORT to generate a getRecord()
    by *value* instead of *by reference*. Seems the overload resolution
    system has changed and discriminate between them using now the exact
    match.
      This was causing InspectorWidget::setRootoccurrence() to fail, the
    getRecord(Occurrence) not corectly resolved always returning NULL.
* Change: In Occurrence, now use INSPECTOR_PV_SUPPORT (instead of PR).
* Change: In SelectionPopup, added a _cellWidget attribute to be able
    to call setShowSelection() in ::mouseReleaseEvent(), same as for
    SelectCommand.
* Bug: In SelectionWidget::changeSelectionMode(), reset the _updateState
    to ExternalEmit in *all cases* at the end of the function call.
    Failing to do that was another cause for the selection check box
    to desinchronize.
2021-11-09 10:53:56 +01:00
Jean-Paul Chaput f5bfeb3eae Fix auto-scaling of the grid over the displayed area.
* Bug: In CellWidget::drawGrid(), the scaling of grid was never recomputed
    according to the zoom level. So in low zoom, it was too fine and
    hidding everything underneath...
      Now always display between 1 and 10 lines. Lines are put on the
    grid step.
      Makes the grid draw in dotted lines, seems to looks nicer.
2021-11-06 13:41:15 +01:00
Jean-Paul Chaput 846ac49ab8 Finally solve the selection desynchronisation problem.
* Bug: In CellViewer::setShowSelection(bool), this slot is connected
    to the hidden 's' menu key. It was toggling state according to
    the state of the *menu key* (Qt) which was *not* kept in synch
    with the state of the CellWidget. So it was causing desinchronized
    selection visibility toggle. Now, ignore the state of the menu
    and toggle the CellWidget state directly.
* Bug: In Selector::attachTo(), when adding the new CellWidget to the
    map<>, the initial flag must be Selector::Selected instead of 0,
    so we see it.
* Change: In CellWidget & ControllerWidget, adjust the default size of
    the widgets (to better suit my display...).

2021-10-30 13:50:44 +01:00
Jean-Paul Chaput d0405d8152 Speed up the database by caching the Occurrence hash.
* Change: In Hurricane::SharedPath, the hash for the shared pathes, which
    serves for Map<> storing, were computed "on the fly" at each
    ::getHash() call, and were involving recursive calls of all the
    hashes along the components of the shared path. This is terribly
    slow especially in a design with a deep hierarchy (typical case
    LS180).
      Now, at the cost of one supplemenental unsigned long in each
    SharedPath, it is only computed once in the constructor, and is
    no longer recursive (only access the *first* tail, if any).
      As a consequence, the re-display computation delay becomes
    bearable. But also speed up any transhierarchical walkthough.

Jean-Paul Chaput 0c0b426894 Follow up of PyModule_GetFilenameObject() modification. 2021-10-01 18:33:47 +02:00
Jean-Paul Chaput e11bd98f52 Correct for various warnings appearing under gcc 8.3.0 (Debian 10).
Note: We don't suppress warnings due to unused variables or functions,
      as we may need them later or in debug mode...

* Change: In Hurricane::DBo::~DBo, add a noexcept(false) because
    constructed by default destructor of derived classes seems to
    loosen it. The right solution whould be to explicitely define
    all virtual destructors (too lazy for now).
* Change: In Viewer::Script, replace the deprecated
    PyModule_GetFilename() by PyModule_GetFilenameObject(), Unicode
    support again...

    revert to C POSIX.
2021-09-30 20:06:48 +02:00
Jean-Paul Chaput 9c71ce8a03 Updated doc of the new Python/C++ template wrapper.
* Change: In Isobar3::PyWrapper, C++ exceptions where not catcheds,
    forgot to call exceptionWrapper().
* Change: In Isobar3, remove unused pyToC<>() flavor where T is a
    simple pointer and the argument is also a simple pointer, does
    not make sense.

Jean-Paul Chaput 16d1da053a Migration towards Python 3, stage 2: C++ template wrapper ready.
* New: In hurricane/configuration, the Python/C template wrapper has
    now all the needed features to mass-migrate Hurricane and the
    ToolEngines.
      The new Hurricane module is named Hurricane3 so it does not
    collides with the old one which is still used. Will do the
    same for all ToolEngines Python wrappers until migration is
    complete.
* New: In unittests/python/, create very basic unit tests for the
    Configuration & Hurricane new template wrapper.
    Note: It is almost impossible to use valgrind on them because
          it doesn't recognize correctly Python allocation mechanism.
	  To make it work, both valgrind & Python needs to be
	  recompiled with special options...
2021-09-25 17:03:14 +02:00
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 f1668cec5f Disable BFD support by default.
* Change: In <tool>/CMakeLists.txt, add an USE_LIBBFD option to
    enable the link against the BFD library. Latest versions seems
    to have changed their API.
* Change: In bootstrap/ccp.by & builder/Builder.py, add an option
    "--bfd" (and self._bfd) to enable BFD support.
2021-07-17 13:01:19 +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 ec3c22547a Bug fixes in the VST/VHDL driver coupled with BlifParser.
* Change: In Hurricane::NetAlias, store additional data in NetAliasName,
    the external status of the former Net. When a Net::merge() is
    performed, we must keep track of whether the merged (destroyed)
    one was external and keep that information.
      Add NetAliasHook::isExternal() & NetAliasHook::setExternal()
    virtual methods.
* Change: In Net::getNet() add a new optional argument to allow the
    search of the net name in *internal* aliases. Otherwise only the
    aliases tagged as *external* will be searched.
      It was a bug that, when looking for a Plug master net by name
    we got an homonymous internal net. In that case we must only
    look for net that are (or where) part of the interface.
* New: In Vhdl::VectorSignal, when a vector contains only one bit,
    unvectorize it, like when it is non-contiguous (we use the
    isCountiguous() method to carry that information).
* New: In Vhdl::VhdlEntity, Catalog::State and NamingScheme, added
    a flag UniquifyUpperCase to uniquify the names in uppercases.
    In case of a clash with the same name in lowercase.
      Prepend 'u' before all previously uppercased letter. For
    example 'VexRiscV' becomes 'uvexuriscuv' (urgh!).
      The Catalog flags is exported to Python for use by the blif2vst
    script.
* Change: In BlifParser, Model::newOne() and Model::newZero(), return
    a new gate each time it is called instead of making just one for
    each Model. This way, if two outside nets are connected to one
    or zero they do not get merged (should work, but will be less
    clear).
* Bug: In BlifParser, Model::connectSubckts(), when looking for the
    master net in the instances models (by name), limit the search
    to the *external* aliases names.
* Change: In NamingScheme::vlogTovhdl(), reactivate the removal of
    two consecutive '_'.
* Change: In cumulus/bin/blif2vst.py, prefix the master cells
    (i.e. components) with 'cmpt_' to avoid clash names with signals
    in VHDL.
2021-04-05 23:53:44 +02:00
Jean-Paul Chaput 9230d52b64 Big bug in HyperNet_ComponentOccurrences::Locator::progress().
* Bug: In HyperNet_ComponentOccurrences::Locator::progress(), (Collection
    locator), the _netOccurrenceLocator (which progess along the various
    Net occurrences of the HyperNet) was not in synch with the
    _componentOccurrence locator of the current net. It was pointing
    to the *next* net occurrence.
      The result was the generation of a path for the net commponents
    that was incorrect (it was the path of the *next* net occurrence),
    and making Occurrence constructor throw an exception.
* Change: In Cell::flattenNets(), DeepNet::_createRoutingPads(),
    Occurrence::Occurrence() and UpdateSession, added even more trace
    informations.
2021-03-23 17:06:02 +01:00
Jean-Paul Chaput cfcd4b7115 Do not for materialization in RoutingPad::setExternalComponent().
* Bug: In RoutingPad::setExternalComponent(), we where always forcing
    the materialization of the RoutingPad (QuadTree insertion). Now
    respect the Go::enableAutoMaterialization() state.
      Forcing the materialization is equivalent to having an
    UpdateSession. So when creating large amount of RoutingPads it did
    result in huge slow down, like in HFNS algorithms.
      With this modification we go down from 6h+ to 4m for the ls180.

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

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

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

Jean-Paul Chaput 642579b444 More fix for the slow display in CellViewer.
* Change: In Hurricane::QuadTree_GosUnder::Locator::progress(), directly
    prune the elements which sizes are under the threshold. This allows
    the too small Instances to be directly skipped. This was the key
    point slowing the walktrough. We were systematically going through
    all the instances (that is consistent with the perf traces).
* Change: In Hurricane::Cell_OccurrencesUnder, add a threshold parameter
    to pass on the QuadTree (through getInstancesUnder()).
      Needed for the CellWidget selection to have the same problem as
    the display itself (select only what is displayed).
* New: In Hurricane::CellView, add two new parameters:
    1. "viewer.minimumSize" set the original size of the window, in pixels.
       (doubled for HiDPI).
    2. "viewer.pixelThreshold", the size, in pixels, under which
       components/instances will not be displayeds.
* New: In CRL/etc/cmos.misc.py, added parameters "viewer.minimumSize"
    and "viewer.pixelsThreshold".

      Put the check in a Contact::_postCheck() function.
* Change: In Hurricane::Contact, replace all the "const DbU::Unit&"

    enlarge too small vertically stacked VIAs. For now just create
    a square ensuring the minimal area. Potentially cause DRC error in

* 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

Jean-Paul Chaput 3e6d5622e8 Improvement on Python interface of Occurrence, Point & CellViewer.
* Bug: In Isobar::PyOccurrence, use "compare by value" instead of

    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.

    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.

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

Jean-Paul Chaput 7e7e7170ba Improve symmetry management for analog designs.
* Bug: In Hurricane::NetRoutingState::getSymValue(), outrageously bad
    computation of the symmetric coordinate when the value was superior
    to the axis... (shame on me).
* Change: In Anabatic::Disjkstra::load(), for symmetrically paired nets,
    check that the axis of symmetry is *outside* the searchArea.
      Otherwise, the two mirrored areas overlaps and the two nets will
    unescapably be on top of each other. Issue a warning but still
    continue.
* Change: In Anabatic::Vertex::isRestricted(), allow perpandicular
    wire to go through struts or thin (less than one routing pitch)
    node. May have to recheck in the future and restrict to struts
    only.
* Bug: In Bora::HVSlicingNode::updateSymNetAxis(), rescursive call in
    child node was not systematically done (bad curly brace position).
      Also checks that symmetries are not empty before accessing the
    front element (one less core dump).

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

Jean-Paul Chaput e9ce33a857 Resistor integration.
* New: In Isobar::PyResistor, manage type RPOLYH and RPOLY2PH.
* Change: In Hurricane::Resistor, rename plate nets from "PIN1" and
    "PIN2" into "t1" and "t2" (try to respect uniform naming scheme).
* New: In Karakaze/AnalogDesign.py, support for reading Resistor
    parameters.
* New: In Orosshi, ResistorSnake.py imported from Mariam Tlili's work
    and associated Resistor.py to make parameter conversion.
      Currently we only uses vertical layout for resistors.
      Added METAL2 horizontal terminals for resistors.
