Jean-Paul Chaput c8fd3c0bec Make a link instead of a move in LEF/DEF parsers CMakeLists. 2021-10-18 18:35:29 +02:00
Jean-Paul Chaput 5343f9c98b Disable tie cell insertion in EtesianEngine::toHurricane().
* Change: In Etesianengine::toHurricane(), no longer call interTies().
    This *should* no longer be needed as almost all standard cells
    (SxLib & FlexLib) already contains polarisation contacts.
      So do not need to disturb the placement.
      Secondly, in presence of a H-Tree, when there is not enough
    space to insert a sufficient number of tie cell, the lefmost one
    in the sub-row is shifted to left, overlaping the H-Tree buffer
    cells. This is a bug (even signaled by a warning). But as this
    part is disabled, I won't correct it soon...

Jean-Paul Chaput e80df4538d Build square external pins instead of "flattened" ones.
* Change: In Cumulus/plugins.block.Block, for standalone block,
    the external Pin where created non-square, the "perpandicular"
    side made a half wire width. But in case the wire width was an
    odd number of physical grid, it was leading to offgrid screaming
    in the GDS driver.
      Now, just make them square...

Jean-Paul Chaput d6b01a557a Fix out-of-bound with short layers names in GdsDriver::GdsStream.
* Bug: In CRL::GdsDriver::GdsStream::operator<<(Cell*), when looking for
    layer names ending with ".pin", must also check that the string is
    at least 4 characters long.

Myrtle Shah 2d24efdb6c Bump minimum CMake version
The CMake version set was so old that obsolete policies were being
enabled and breaking FindPython. 2.8 should still be old enough not to
cause problems for any current users.

Jean-Paul Chaput f58212eb96 Fix incorrect application of xTracksReservedMin in Katana.
* Bug: In KatanaEngine::annotateGlobalGraph(), the minimum track reservation
    was not applied correctly. Instead of adding the *difference* between
    the minimum and the current reservation, the minimum was simply added.
    Leading to too high reservation. And loss of control about what we
    were doing on the edges capacities...
      Really stupid.

Jean-Paul Chaput fd2c92f442 * Change: In cumulus/plugins.chip.powerplane, when the vertical rail is
large enough instead of creating one big via along the horizontal
    cell power lines, we create one big VIA at each end. To avoid to
    create too massive obstructions.
      But the thresold was too high for cmos45, leading to short with
    the clock tree trunk.

Jean-Paul Chaput b9a1395b4b Improve Coriolis root directory search in coriolisEnv.py.
* Change: In bootstrap/coriolisEnv.py, when all tries to locate the
    installation root in predefined locations, try the directory the
    script is installed in.
      This allows for a user to use an installation made in another
    user's account.

Jean-Paul Chaput b2e265f73e Increase bloating in Etesian "nsxlib" profile, for ls180+cmos45. 2021-10-07 00:51:15 +02:00
Jean-Paul Chaput 66361fcf3d Correct catastrophic memory bloat in Anabatic::layerAssign() step.
* Bug: In Anabatic::_desaturate(), the set of invalidated GCells was never
    cleared between iterations of desaturated GCells. This was not a
    memory leak per se because, in the end, the set was freed. But it did
    induce a gigantic bloating in memory. This finally explain the strange
    slow down in that stage.
      Detected in ls180+cmos45.
* Change: In Anabatic::GCell, add a flag for each depth to avoid
    desaturating twice the same GCell (maybe not needed now that the
    bug is corrected, but it ensure a no-looping).

Jean-Paul Chaput b1bc22f8e7 Bad computation of minimal area of stacked VIAs in Cumulus.
* Bug: In cumulus/plugins.block.configuration.GaugeConf.expandMinArea(),
    The minimal length of the segment intermediate wires where computed
    for the minimal area using an integer division ( // ), which is
    stupid for less than 1.0 values. They are real quantities at this
    point...
      This was making the DRC of ls180 failing.

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...

Jean-Paul Chaput c28fe3402b Take account of more Python site-packages.
* Change: In bootstrap/coriolisEnv.py, the script was looking to
    pythonX.Y (like "python2.7" or "python3.6") only. Now added
    "major" only directories like "python2" or "python3".

* Bug: In Hurricane::Backtrace(), the std::regex supplied by gcc 4.8.5

    revert to C POSIX.

* Bug: In Anabatic::AntennaProtect, if the diode cell exists *but* the

    the diode protection instead of making a divide by zero.

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 844db44ebf Rename pyTypePostModuleInit<> to pyTypePostInit<> (clearer). 2021-09-25 19:20:57 +02:00
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...
