Jean-Paul Chaput 96e6c9dd06 Fix a sync problem between the EquiWidget and the SelectionWidget. 2023-05-06 18:13:39 +02:00
Jean-Paul Chaput c53fc01cb2 Add Rectilinear & "cut" support to the extractor.
Note about the managment of VIA & cuts: Components using a layer which
  is a ViaLayer, that is one containing more than one BasicLayer,
  multiple tiles are created in QueryTiles::goCallback().
    Components that have a single BasicLayer of "cut" material will
  also have their multiples tiles created in QueryTiles::goCallback().
    Rectilinear components will have their multiples tiles created
  in Tile::create(). Tile::create() return not all the tiles but the
  one used as root (for the union find).

* New: In SweepLine::_buildCutConnexMap(), when using a "cut" layer
    in a standalone way, and not as part of a ViaLayer, we do not
    automatically know to which layer above & below they are connected.
      We build a table for each cut layer, based on the ViaLayer,
    to know all tops & belows layers they connect (this is cumulative,
    in the case of "cut" towards the substrate).
      Then in Tile::create(), we not only create the tile for the "cut"
    but also in thoses connected layers (and link them in the union
    find).
* New: In Tile::create(), when we encounter a Rectilinear, break it
    into rectangles and make as many tiles. All tiles linked to the
    same root in the union find.
* Bug: In Hurricane::Rectilinear, ambiguous specification of the set
    of points defining the shape. I did suppose that the start and and
    point where not the same the last edge being between them.
      But if FlexLib, it uses the GDSII inspired convention where the
    first and last point must be the same, to indicate a closed contour.
      This difference was not causing any difference with the drawing,
    but it was a problem for getAsRectangle(). This was creating a
    "false" extra vertical edge leading to a bigger rectangle.
    And this, in turn, was making "false" intersections in the
    tiling/sweepline of the extractor.
      Add a more thorough checking of the points vector.

Jean-Paul Chaput 52fd1c1c40 Add vertical rectangles partionning to Rectilinear.
* New: Rectilinear::asRectangles(), decompose the Rectilinear into a
    set of non-overlapping rectangles sliced vertically.
      This not a mathematical minimum set. But should be speedier.
      Done using a sweepline processing the vertical edges.
      Specially suited for use in the extractor which basically
    manage only rectangles.
      Simple algorithm described in pp. 9-11 of Extractor notebook.
      Tests done with unitests/python/test_rectilinear.py, the
    Rectilinear here should cover all the sweepline cases.

Jean-Paul Chaput a31cf3d334 Fix SRAM import hierarchy for new coriolis namespace. 2023-04-26 11:46:53 +02:00
Jean-Paul Chaput 4c7cf227be Add ability to "filter out" buried net in TabEquipotentials.
Definition: A buried net is a net that has no components at the top
Cell level. Typically example is a wire internal to a standard cell.
Those nets, while part of the complete design (flat) are not part
of the top netlist, and we may want not to see it.
  A buried net is slighly different from a deep net. While a deepnet
is also not reaching the top level cell, we created it at top level
to be processed by the router (virtual flatten).

Jean-Paul Chaput d928a3c7a5 Merge branch 'devel' of gitlab.lip6.fr:vlsi-eda/coriolis into tramontana 2023-04-13 14:05:48 +02:00
Jean-Paul Chaput c3bed61257 Full transhierarchical implementation done.
* New: Equipotential elements includes now:
    1. Components at the top level (the cell owning the Equi).
    2. Nets at the top level. If an equi include all the components
       of a Net, own the Net, not all it's individual components.
    3. Other equipotentials from the Instances immediatey below.
       Thoses equis should be equivalents to the Plug of the Net.
       They are stored in the form of Occurrences <Instance,Equi>,
       the relation is stored on that Occurrence.
* New: Equipotential::getFlatComponents(), a collection to recursively
    get all the *component* occurrences of the equi. Transhierarchically.
    Go through components, nets components, and recursively through
    the child equis.
* New: EquipotentialRelation, the master of this relation is the
    Equipotential and the slaves, all its elements.
* Change: In Tile, in case the tile is build on a deep component,
    we trace up the Equipotential it belongs to in the Instance
    level immediately belonging to the Cell under extraction.
    They must exists as we extract from bottom to top all the
    master cells. So we have, for that tile an Occurrence
    <Instance,Equi> that we can store in the current Equi level.
* Change/Bug: In Tile, add an Id to be reliably sort the tiles
    in the IntervalTree. As we replaced the tile component occurrence
    by a <Instance,Equi> we were having multiple tiles with the same
    equi. This was causing havoc again in the IntervalTree.
      Should add a check in the RbTree for elements with the
    exact same key, but that would imply passing a new template
    parameter for the "equal" function.

Jean-Paul Chaput 518a376c01 Transhierarchical/flat extraction work, no netlist rebuild yet.
* Bug: In Interval::intersect(), bad condition check in strict mode.
* Change: In Occurrence::operator<(), change the sorting criterions
    so that the ones with no paths are "lower", then the one with
    no entities, then compare entities Id then Path hashes.
* Change: In Occurrence::getCompactString(), to be more readable,
    suppress leading and ending "<>".
* Change: In IntervalTree, now use an IntervalDataCompare to control
    the ordering of the nodes inside the tree. This may be needed
    when IntervalData is build upon a pointer, we don't want to
    sort on pointer values (non deterministic) .
* Bug: In IntervalTree::postRemove(), there was an incorrect computation
    of the updated childsVMax.
* Bug: In IntervalTree::beginOverlaps(), miscalculated leftmost
    interval overlapping.
* Bug: In RbTree::remove(), when exchanging the removed node for a
    leaf, fully swap the nodes contents, was incompletly copied before.
* New: In CellWidget, add new slots selectSet(OccurrenceSet&) and
    unselectSet(OccurrenceSet&), to be able to select/unselected sets
    of Occurrence (for use by TabEquipotentials).
* Change: In EtesianEngine, no more need to remove leading/ending "<>".
* New: In Tramontana, use a Query to find all the Occurrence under
    an area. Previously we were using Cell::getOccurrencesUnder()
    which *do not* return the components in instances, so we would
    have been unable to find trans-hierarchical shorts circuits.
* New: In tramontana, now use a Relation to tag all the components
    belonging to an Equipotential.
* Change: In Equipotential, store everything under the form of
    Occurrence, instead of Components. Due to the way the Occurrences
    are sorted, the one holding Components should be firts.

Jean-Paul Chaput 23c0c24c0f Non-hierarchical, metal only, rectangle only, extractor is now working.
* New: In Tramontana,
  * Multi-layer support for the swap line. Split VIAs into their
    various metal plates and link the two relevant tiles, ensuring
    connexity between layers.
  * Improved Equipotential information rebuild. Try to rebuild more
    closely the Net characteristics. Improved tab widgets.

Jean-Paul Chaput 2568a1a496 Added deletion tests for RbTree & IntervalTree in unittests. 2023-03-28 15:12:31 +02:00
Jean-Paul Chaput e22e7f7476 IntervalTree is now support multiple intervals with same lower bound.
* New: Interval::CompareByMinMax, lexicographical comparison of
    Intervals, first compare the lower bound (VMin) then the
    upper bound (VMax). Needed for IntervalTree.
* Change: In IntervalTree, the key comparison was only based on
    the lower bound (VMin). That means that the tree would accept
    only one interval for a given VMin. You couldn't store both
    [1:4] and [1:5]. Now use CompareByMinMax that allows it.

    to force building against the old one.

Jean-Paul Chaput c7608998ce Comprehensive LD_LIBRARY_PATH init in coriolisEnv.py.
* In bootstrap/coriolisEnv.py, under WSL it seems that setting up the

    To avoid that, use ldconfig to import all the known paths into
    LD_LIBRARY_PATH.
