Jean-Paul Chaput 6bc8751879 Change the type of parameters for Etesian from Percentage to Double.
* Change: In CRL/etc/common/etesian.py, use double parameters
    instead of percentages to simplify. For space margin and form
    factor. This need the rewrite of coriolis2/settings.py in
    alliance-check-toolkit.

Jean-Paul Chaput 3dbaea6aca Bug fix, restore the FreePDK 45 (real) support.
* Change: In CRL::LefParser::_macroCbk(), create a Catalog entry for the
    newly read MACRO (that is Cell) and sets the Logical, Physical,
    InMemory and TerminalNetlist flags.
* Bug: In CRL::LefParser::_siteCbk(), check for NULL cell gauge.
* New: In CRL::AllianceFramework, add setCellGauge(), to set the default
    cell gauge. Exported to Python.
* Change: In CRL/etc/common/technology.py, create variables for VIA
    layers, so we can modify their properties afterwards.
* New: In CRL/etc/node45/freepdk45, port the configuration files to the
    new Python "importable" format.
      Note: in kite.py, all the gauges (Routing & Cells) must be named
    "LEF.CoreSite" to please my LEF parser, so it can match the gauge
    name with the SITE name for standard cells.
* Bug: In Anabatic::NetBuilderVH::_do_2G(), forgotten to be reimplemented
    from the base class. Simply redirect to _do_xG().
* Change: In Katana::PowerRailsPlanes::PowerRailsplanes(), create plane
    from the layers in the RoutingGauge and their associated blockages
    instead of sweeping through all the basic layers.
      Allow to distinguish bewteen "METAL" (symbolic) and "metal" (real).

Jean-Paul Chaput e711ce8dd2 More configuration parameters for P&R Conductor, for experimenting.
* Change: In Hurricane::Viewer::ExceptionWidget & CRL/python/helpers/io.py,
    downscale icons for non-HiDPI screen.
* Change: In CRL/etc/common/display.py, change the display threshold of
    METAL1 layer so it do not appear at high scaling.
* New: In Etesian, activate the "setFixedAbHeight()" feature and export it
    to Python. Allows to increase the space margin at constant height.
      To be used by the P&R conductor.
* Change: In Unicorn/cgt.py, when running a script, insert the current
    working directory at head of the sys.path, not at the end. So installed
    modules do not shadow local one.
* New: In Anabatic::Edge, new accessor "getRawcapacity()" to know the full
    capacity of the edge, that is, the real maximum number of tracks that
    can go through the associated side.
* Change: In Katana/BloatProfile/Slice::tagsOverloaded(), bloating policy
    change, now bloat all the instances under the GCell, not only the first
    one.
* Change: In KatanaEngine::runGlobalRouter(), restore the search halo growth
    policy to expanding of 3 GCells every 3 iterations.
      New metrics displayed, the edge wire length length overload.
* Change: In cumulus/plugins/ConductorPlugin.py, now accepts the following
    configuration parameters:
      - "anabatic.globalIterationsEstimate", maximum number of global
        iterations during the bloating computation passes.
      - "conductor.useFixedAbHeight", tells wether the additionnal blank
        space must be added so the aspect ratio is kept or the height is
	kept (and the block become wider).
    Disable the display of "rubber" to unclutter a little the view.

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).

Jean-Paul Chaput 24dedce09c Added core2chip support for Phenitec80.
This commit degrades the run success rate of ARMv2a to 87% (40 iters).
* New: In CRLcore/etc/.../kite.conf, add configuration parameters:
      katana.termSatReservedlocal
      katana.termSatthreshold
    for the new edge capacity computation system.
* New: In CRLcore/etc/symbolic/phenitec06/, add support for N. Shimizu
    small I/O pads (supplied in phlib80). Tune various parameters of
    Anabatic/Katana to increase routing success.
* Change: In CRLcore/alliance/ap/ApParser, make Pin external components,
    so RoutingPad will be build upon in global routing.
      Do not complain when a I/O pad has a physical instance that did
    not exists in the netlist. Just create it (appeared in phlib80).
      When no netlist instance exists in a pad, the pad Cell is still
    considered as terminal.
* New: In Etesian::BloatCells, new profile named "3metals" better suited
    for two routing metals technologies (i.e. Phenitec).
* New: In Anabatic::RawGCellsUnder, new CTOR which take only source &
    target points instead of a segment. Needed to manage wide segment for
    which the axis to consider is not that of the segment (one axis for
    each track it intersect).
* New: In Anabatic::GCell, add a RoutingPad count attribute, for Edge
    reservation computation.
* New: In AnabaticEngine::computeEdgeCapacities(), instead of decreasing
    all edges of a fixed amount (hTrackReservedLocal), guess the GCell
    cluttering from the number of RoutingPads that it contains.
      For non-saturated GCells, the four edges are decreased by the number
    of RoutingPads. We use the maximum from the two neigboring GCells.
    The hTrackReservedLocal parameter is now used only as a *maximum*
    that the edge reservation can reach.
      If a GCell is saturated (more than 8 RoutingPads, the saturation is
    propagated horizontally to 2 neigboring GCells).
* Change: In AutoContactTerminal::getNativeConstraintBox(), use a more
    flexible gauge name matching for terminal vertical extensions correction.
    Namely, match all "msxlib*" kind of gauges.
* Change: In AutoSegment::setAxis(), add the ability to force the axis
    position, even if it is a non-canonical segment. Maybe needed in the
    initialisation steo, before the first canonisation is performed.
* New: In NetBuilder, added new methods _do_1G_1PinM1() and _do_2G_1PinM1(),
    to manage coronas for Phenitec designs.
      To avoid various side effects from segments being too close from
    the north / east side of the routing area, make those segments fixeds.
* Change: In KatanaEngine::annotateGlobalGraph(), the management of wide
    wires was wrong. The axis to use to find the underlying GCells is the
    one of the track, not of the segment. This was creating bad edge
    capacity computation under the power ring of a block and subsequently
    routing failures.
* New: In Kanata::Manipulator, added method reprocessParallels(), not used
    though, but keep it anyway, might be of use later...
* New: In Kanata::Manipulator, added method avoidBlockage() for terminal
    METAL2 in non-preferred direction, restrict the terminal and turn
    constraint box at the current position of the perpandicular, so it
    doesn't create a deadlock in METAL2.
* Change: In SegmentFsm::conflictSolveByPlaceds(), if we cannot break
    using the whole overlap, try the first atomic overlap.
* New: In SegmentFsm::_slackenStrap(), manage conflict between a non-prefered
    segment and a blockage, this when to call avoidBlockage()...
* New: In Katana::Configuration, management of the new edge computation
    parameters:
      katana.termSatReservedlocal
      katana.termSatthreshold
* New: In Cumulus/plugins/Core2Chip, support for Phenitec I/O pads.
2019-09-17 17:05:54 +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).
2019-07-28 23:20:00 +02:00
Jean-Paul Chaput 9f69230837 Correct CellWidget & CellPrinter to be really WYSIWYG.
* Change: In Hurricane::CellWidget, new "isPrinter" attribute to know if
    the CellWidget is used as a device for printing.
      New function copyExtensionsGos() to duplicate the ExtensionGo drawing
    callbacks. This is a temporary hack until the ExtensionGo are made static
    to be shared by all CellWidgets.
      In _redraw(), the DrawingQuery flags were not correctly reset between
    different stage of the drawing. This was resulting of uneeded walkthough
    of the slicing tree, along with incorrect display of some of the layers
    (i.e. rubbers where diplayeds when ExtensionGos where active).
* Change: In GraphicKatanaEngine, fine tune the display of GCells for printing
    CellWidget.
* Change: In Hurricane::CellPrinter, copy all the settings from the palette
    of the reference (graphic) CellWidget into the printer CellWidget.
    Also copy the ExtensionGos callbacks so we can print them. Use the
    new CellWidget attribute "isPrinter" for the callbacks to be able
    to adapt to Printer settings.
* Change: In Hurricane::Time::getStringTime(), only print two decimals
    for time durations.
2019-02-20 18:24:43 +01:00
Jean-Paul Chaput 3f73b9d033 Anlog integration part I. Atomic devices support (transistors).
* Change: In boostrap, remove support for Chams.
* New: In Hurricane::Technology, added support for DTR rules, UnitRule,
    PhysicalRule and TwoLayersPhysicalrule. Added devices descriptors and
    models descriptors (for Spice). Spice description is not used yet
    but kept anyway in case of future use.
* New: Hurricane::Analog whole library and it's Python interface. This
    provides support for transistors, capacitors and resistors. Only
    transistor support is fully implemented as of now.
* New: In CRL/python/coriolisInit.py, read configuration files for the
    Analog extension (analog.conf & devices.conf). Thoses are optionals
    and a simple warning is issued if not found.
      Added helpers/AnalogTechno.py DTR loading helper.
      Add analog configuration files for 180/scn6m_deep_09.
* New: Oroshi tool that provides actual layout drawing for transistors.
2018-10-01 16:52:17 +02:00
Jean-Paul Chaput 55a29488c9 Correct handling of lambdas & microns in configuration files.
* Bug: In CRL/etc/NODE/VENDOR/Technology.conf, the database must be configured
    as early has possible so the functions ensuring length conversions can
    work correctly (l(v), u(v)). So we can no longer rely on a table to be
    read after the execution of the file. We perform a direct call to the
    helpers.Technology.initTechno() function. And it must be made first
    thing.
      In all tables taking dimensions, we must use one of the converter
    function helpers.l(v), helpers.u(v) or helpers.n(v) so the the value v
    get converted in lambda, microns or nanometer (resp.). Make the
    modifications in all technology.conf and kite.conf files.
* Change: In CRL/coriolisInit.py, remove the technoConfig variable that has
    been replaced by a direct call to helpers.Technology.initTechno().
* Change: In CRL/helpers.Alliance.loadRoutingGaugesTable(), no longer try to
    convert coordinates, they must already be in DbU.
* Change: In CRL/helpers.__init__.py, remove lambdaMode() and micronsMode()
    they could not be made to work as expected. Create l(), u(), n() as
    replacement.
2018-07-16 11:32:40 +02:00
Jean-Paul Chaput 0902b21f23 Added support for huge approximated polygons (for photonics).
* New: Hurricane::Triange as been renamed into Hurricane::Polygon.
    Add support for convex polygons. Polygon are approximateds by
    excess by a manhattan rectilinear polygon (with potentially
    thousands of vertexes). To reduce the memory footprint,
    compaction techniques reducing by at least a factor 4 has been
    implemented. We could go further by only storing the non-repetitive
    part of the edge (defined by the integral fraction dY/dY).
    We will see, if the program slows too much.
      The manhattan approximate is always computed but displayed
    only if the polygon grid step is greated than 4 pixels.
      The level of approximation of the polygons can be controlled
    through the "DbU::_polygonStep" parameter.
* Change: In CRL/coriolisInit.py and CRL/helpers/Technology.py, regroup
    all DbU related parameters into "technoConfig" (i.e. suppress
    "viewerConfig"). Update all the relevant technology.conf configuration
    files.
      Change the loader behavior so that "technoConfig" is read first
    and is now responsible for creating the Technology of the DataBase.
* New: In Hurricane::CellWidget, added support for displaying mahanttanized
    polygons.
* Change: In documenation/scripts/expample/polygons.py, perform (I hope)
    a comprehensive test of the polygons (check all slopes, clockwise and
    conter-clockwise).
* New: In Hurricane::DbU, added template to manage vector<> of DbU.
    Support for the "polygonStep" parameter.
2018-05-04 17:06:41 +02:00
Jean-Paul Chaput 3d0431b238 In CRL, update real conf. files. Smarter management of pin in LEF parser.
* Change: In CRL Core, etc/, update the configuration files of real
    technologies. Mostly for FreePDK 45. This work is also done for
    AMS c35b4 (350nm) but in a private (SoC) git repository.
      Added a new parameter 'lefImport.minTerminalwidth' for the
    minimum size (width) of a metal1 terminal in standard cells.
      Corrected bug of the minimum trace level which must be
    initialized to a great value and *not* zero;
* Change: In CRL Core, BlifParser, detect when there is no tie low
    or tie high defined, issue an error (connexion left open) but
    continue.
* New: In CRL::RoutingLayerGauge, new overlad of getTrackPosition()
    with the parameter set of getTrackIndex(). Used to know if a
    terminal is on-grid or not.
* New: In CRL::LefImport, smarter management of metal1 pins. Adds a
    _pinPostProcess() function to select the external components
    among the various shapes. If the gauge is VH, all the pin rectangles
    are translateds into vertical segments (even if the metal1 gauge
    says the tracks are horizontals).
      The _pinPostProcess() function adds as external components of
    a net, only the segments of a sufficent width as given in
    'lefImport.minTerminalWidth' and that are on-grid.
2018-01-06 16:18:33 +01:00
Jean-Paul Chaput 24d8fe5957 Cleaner support for real technologies (Hurricane, CRL Core configuration).
* Change: In Hurricane::Technology, in all the layer connexity methods
    (getLayers(), getMetalAbove(), getCutAbove(), getViaBetween(), ...)
    the "useWorking" parameter is replaced by a more accurate "useSymbolic".
      BEHAVIOR CHANGE: formerly, if a symbolic layer was requested, and
    none was found, NULL was returned. Now, if the symbolic layer is not
    found, we try to return the associated real one (same layer mask,
    but not flagged as symbolic, and usually with a lowercase name).
      All thoses changes have been propagated to Python bindings.
* Change: In Hurricane::BasicLayer and derived classes, rename the
    "isWorking" attribute into "isSymbolic" (to match the technology
    renaming).
* Change: In Hurricane::Cell::flattenNets(), ignore power, ground and
    blockage nets for the flatten.
* Change: In CRL Core, in coriolisInit.py and Technology.py helpers,
    rename the tables describing the technology as follow:
      - symbolicLayersTable --> compositeLayersTable
      - workingLayersTable  --> symbolicLayersTable
      - symbolicRulesTable  --> layersExtensionsTable
    This is to give the table names a more clearer semantic after
    merging real technologies configurations (testbench AMS c35b4).
      In particular, we need to define a composite layer for the
    real VIAs, and not only the symbolic ones. And with correct
    enclosures expressed in real dimensions (microns).
2017-12-27 13:13:29 +01:00
Jean-Paul Chaput bc1c7838d1 Reorganisation of technology configuration files.
* Change: In CRL Core, in coriolis2/etc the file an directory structure
    describing the technonolies is modified.
      Before, one technology was split in two: the symbolic part that
    may be shared across multiple real technology and the real technology
    itself. To configure this we needed in ".coriolis2/techno.py" two
    variables:
      * symbolicTechnology.
      * realTechnology.
      After, we duplicate the symbolic technology in each real ones, so
    to configure we only have to refer to one technology with the
    variable:
      * technology.
      Pure sympolic technologies are still availables, associated with
    a dummy real one.
      We provides:
      * 180/scn6m_deep_09  for MOSIS 180nm
      * 45/freepdk_45      for FreePDK 45nm (work in progress).
      * symbolic/cmos      for classical Alliance symbolic.
* Change: In CRL Core python/helpers, SymbolicTechnology.py and
    RealTechnology.py are now grouped under Technology.py.

EricLaoGitHub 06d818695f Dijkstra can handle mixedsignal wires. 2017-06-21 18:02:37 +02:00
Jean-Paul Chaput e12e45e495 Rename SymmetricStage into PairSymmetrics, plus small cleanup. 2017-05-26 13:32:30 +02:00
Jean-Paul Chaput db8e51524f Deterministic destruction of Components.
* Change: In Hurrican::Component::_preDestroy(), the cascaded destruction
    of slaves Components and subsequent ring merge and Rubber creation
    was using set<> sorted on pointer values. This was making the order
    of destruction of the slaves components non-deterministic. Now the
    sets are sorted according to their id (see Entity).
* Change: In Hurricane::SharedProperty, the _ownerSet is now a vector<>
    instead of a set<>. This will slow the search process, but hopefully
    this is needed only during construction/destruction of a Property
    so the slow down shouldn't be too much.
      This has also an impact on Hurricane::Relation.
2017-05-03 18:09:51 +02:00
EricLaoGitHub 8bf1f63557 Pre-commit for updating git depositary. 2017-04-18 11:58:55 +02:00
Jean-Paul Chaput 880b1817ce In CellPrinter, adds the DPI and the Orientation as config. parameters. 2017-03-15 17:59:00 +01:00
Jean-Paul Chaput 00ea8f0205 Display selection when drawing on printing devices.
* Bug: In Hurricane::CellWidget, when setting up a state of a CellWidget,
    the selection was not copied. Now copy the SelectorCriterion (clone).
* New: In Hurricane::SelectorCriterion, add a clone() method.
* Change: In CRL Core, in etc/common/display.conf, for the Printer.Coriolis
    style, lower the thresold of display for the substrate layers so they
    are shown even in small zoom mode.
2017-03-15 14:37:32 +01:00
Jean-Paul Chaput 4163fc044a In Anabatic, check if there is at least one METAL1 in singleGCell().
* Bug: In Anabatic::singleGCell(), in some analogic design, there may be
    not a single METAL1 in the GCell. Issue a clean warning instead of
    going ashtray.
* Change: In CRL.etc/technology.cong & CRL.etc/display.conf, add a "metbot_r"
    as a real layer when "metbot" symbolic layer is distinct from a normal
    metal.
2016-12-15 19:25:05 +01:00
Jean-Paul Chaput ce00b37cbf Enable the display of GCells as a density map (and not boundaries).
* Bug: In Anabatic::RawGCellsUnder, *again*, the north and east borders
    of the whole area *are* includeds (shut up disgraceful warning).
* New: In Anabatic::GCell, add a display mode to select between boundary
    display (for analogic) and density display (for numeric).
* Bug: In KatanaEngine::runGlobalRouter(), do not check if an Edge cannot
    be desatured when the vector or overloaded Edges is empty.
    (one less disgraceful warning)
* New: In GraphicKatanaEngine::drawGCell(), support for drawing the GCells
    in density mode. Use the fire scale and the MaxDensity mode.
      Setup the GCell drawing mode in GraphicKatanaEngine::initGCell().
* Change: In GraphicKatanaEngine::drawEdge(), adjust the various thresholds
    for showing the Edge and its label.
* New: In CRL Core, adds "anabatic.gcell.displayMode" to the set of Anabatic
    parameters.
      Adjust the showing threshold for GCells in "display.conf" so when the
    zoom level is low, we still can see the density map.
2016-09-10 18:49:48 +02:00
Jean-Paul Chaput 601e3d3da1 Anabatic transient commit 8. More Dijkstra bugs correcteds.
* Bug: In Anabatic:
    - In _propagate(), on reaching a target, forgot to remove it from
      the queue before pushing it back with the new distance. It also
      simplificate the core algorithm as target as treated normal nodes.
* New: In Anabatic:
    - Update cdebug to use the fastest macro version.
    - More readable drawings of GCells and Edges.
    - Added timer support.
    - The distance is now computed in DbU::Unit (aka long) and not in
      normalized float.
    - The distance function is now a callback (std::function<>) that
      can be changed (a default is provided at initialization).
    - New concept of branch in the agglomerated connex component.
      Each trace back part create a "branch" (tagged with a "branchId").
      When a node is reached with the same distance, but from two
      different branches, choose the the branch that was lastly created.
      This create a slightly different tree which grows outward from
      the newest branches.
    - Makes the horizontal edges *slightly* longer than the vertical ones
      to skew the tree to use vertical edges, as it is usually less
      congested than the horiontal one (due to metal1 cell terminals).
      It is also my understanding that it is useful to reduce the
      number of vias, whithout introducing a via cost.
* New: In Bootstrap:
    - Script sprof.py to perform sprof & demangle libraries execution
      profile.
* ToDo: In Anabatic:
    - Corner optimization. Sometimes when two corners are possible, the
      wrong one is choosen. That is, one of it's edge cannot be used for
      further grow of the tree.
2016-06-17 13:09:34 +02:00
Jean-Paul Chaput 747027f23a Simplification of the Hurricane::Observer mechanism.
* Change: In Hurricane::Observer, simplification of the template so that
    we can use it directly instead of creating a derived class with an
    implementation of Observer::notify(). Now the implemenation is the
    same for all and just calls a notify() method on the owner object.
      Create a StaticObservable for fast access of the observers. This
    is mainly a fixed size table (array<>) with oberservers at known
    indexes. This way we can go from the obervable to the observer
    owner in one indirect access (or so I hope).
* Change: In Hurricane::CellViewer, use the new observers.
* Change: In Hurricane::ControllerWidget, use the new observers.
* Change: In Hurricane::CellWidget, set the winidow initial size to a
   more sensible 500px.
* Change: In CRL::LibraryManager, use the new observers.
* Change: In CRL::LibraryManager, use the new observers.
* Change: In CRL, in display.conf & technology.conf, modification for
    the ST hcmos9gp capacitors.
2016-06-03 17:19:46 +02:00
Jean-Paul Chaput a4655aec8b Anabatic transient commit 2.
* Change: In Hurricane, in CellWidget, enable the drawing of ExtensionGos
    according to the the threshold paramaters (as layers do).
* Change: In CRL Core, provide DrawingStyle for Anabatic::GCell &
    Anabatic::Edge. Use the exact name of the ExtensionGo.
      In kite.conf, add settings for the size of an edge as the optimal
    size may change between analog & digital designs.
* New: In Anabatic:
    - Support for fast position query using a matrix.
    - Computation of the Edge capacity, based on the routing gauge parameters.
    - Graphic display of the edges capacity. Added configuration
      parameters to size the bounding box of an Edge.
* Bug: In Anabatic:
    - GCell::_moveEdges was both too complex (some cases never arise the
      way we divide GCells) and bugged.
2016-05-26 13:56:16 +02:00
Jean-Paul Chaput 82cff69d9f Complete rewrite of the trace system (now a stream).
* Change: In Hurricane, in Flags add operator overload for "int" type
    and not only "unsigned int". Otherwise the compiler complaints about
    ambiguous overload when using enum values which are considered as
    "int".
      Simpler code for the BaseFlags::contains() method.
      Added implicit conversion from BaseFlags toward bool type.
* Change: In Hurricane, in Commons, complete replacement of the previous
    two trace systems (trace & ltrace) by a stream-based one.
    As it is a true object it is much less fragile than the one based
    on defines (but maybe a little slower).
      Define a reservation table for the trace levels for all the
    Coriolis & Chams components.
* Change: All tools, use the new trace system.
2016-05-17 23:00:06 +02:00
Jean-Paul Chaput 4262d396e9 Added METCAP layer, for MIM capacitors. 2016-03-06 12:40:23 +01:00
Jean-Paul Chaput b57c81dda8 Bug in Cell::_preDestroy().
* Bug: In Hurricane, in Cell::_preDestroy(), the classic mistake again:
    do not iterate over a collection while deleting it's elements.
    Now should be safe.
* Change: In CRL Core, set the default display style to "Alliance.Classic [black]"
    (my favorite).
2016-02-23 17:19:42 +01:00
Jean-Paul Chaput ed557d9027 Added support for "same layer" dogleg. Big fix for pad routing.
* Change: In Knik, in Vertex, add a "blocked" flag to signal disabled
    vertexes in the grid (must not be used by the global router).
      Modificate the Graph::getVertex() method so that when a vertex
    is geometrically queried, if is a blocked one, return a non-blocked
    neighbor. This mechanism is introduced to, at last, prevent the
    global router to go *under* the pad in case of a commplete chip.
* New: In Katabatic, in AutoSegment, a new state has been added: "reduced".
    A reduced segment is in the same layer as it's perpandiculars.
    To be reduced, a segments has to be connected on source & target to
    AutoContactTurn, both of the perpandiculars must be of the same layer
    (below or above) and it's length must not exceed one pitch in the
    perpandicular direction.
      To reduce an AutoSegment, call ::reduce() and to revert the state,
    call ::raise(). Two associated predicates are associated:
    ::canReduce() and ::mustRaise().
      Note: No two adjacent segments can be reduced at the same time.
* Bug: In Katabatic, in GCellTopology, add a new method ::doRp_AccessPad()
    to connect to the pads. Create wiring, fixed and non managed by
    Katabatic, to connect the pad connector layer to the lowest routing
    layers (depth 1 & 2). The former implementation was sometimes leading
    to gaps (sheared contact) that *must not* occurs during the building
    stage.
      Remark: This bug did put under the light the fact that the initial
    wiring must be created without gaps. Gaps are closed by making doglegs
    on contacts. But this mechanism could only work when the database if
    fully initialised (the cache is up to date). Otherwise various problems
    arise, in the canonization process for example.
* New: In Katabatic, in AutoContactTerminal::getNativeConstraintBox(),
    when anchored on a RoutingPad, now take account the potential rotation
    of the Path's transformation. Here again, for the chip's pads.
* New: In Kite, support for reduced AutoSegment. TrackSegment associateds
    to reduced AutoSegment are *not* inserted into track to become
    effectively invisibles. When a segment becomes reduced, a TrackEvent
    is generated to remove it. Conversely when it is raised a RoutingEvent
    is created/rescheduled to insert it. All this is mostly managed inside
    the Session::revalidate() method.
* New: In Kite, in KiteEngine::createGlobalGraph(), in case of a chip,
    mark all global routing vertexes (Knik) that are under a pad, as blockeds.
* Bug: In Cumulus, in PadsCorona.Side.getAxis(), inversion between X and
    Y coordinate of the chip size. Did not show until a non-square chip
    was routed (i.e. our MIPS R3000).
* Change: In Stratus1, in st_placement.py add the ClockBuffer class for
    backward compatibility with the MIPS32 bench. Have to review this
    functionnality coming from the deprecated placeAndroute.py.
      In st_instance.py, no longer creates the Plug ring of a Net.
    In my opinion it just clutter the display until the P&R is called.
    Can re-enable later as an option (in Unicorn).
* Change: In Unicorn, in cgt.py, more reliable way of loading then running
    user supplied scripts. Borrowed from alliance-checker-toolkit doChip.py	.
2015-08-16 23:29:28 +02:00
Jean-Paul Chaput db60fe0aa6 New coriolis launcher. Configuration files cleanup.
* Change: In CRL Core, simplify the loading sequence. The technology,
    both symbolic and real is now loaded directly from coriolisInit.py
    and not through the Alliance loader. This was a leftover from the
    time configuration was in XML. Remove others traces of XML loading.
      Remove SYMB_TECHNO_NAME, REAL_TECHNO_NAME & DISPLAY from the Alliance
    environement, as they was no longer used.
      Note that technology *still* need to be loader *after* Alliance
    framework has been initialized.
      Gauge information is moved from <alliance.conf> to <kite.conf>.
* Bug: In Coloquinte, in optimization_subproblems.cxx static variables
    must not be inlined. Generate a problem when linking in debug mode
    (seems the symbol gets optimised out).
* Bug: In Katabatic, in Grid::getGCell(), when the coordinate is *outside*
    the area, do not try to find a GCell, directly return NULL.
* New: In Unicorn, create a generic command launcher named "coriolis" which
    automatically take cares of all environement setup, then run a command
    by default, it's <cgt>, but it can be anything. For example: <zsh>.
2015-04-13 18:54:09 +02:00
Jean-Paul Chaput a7c4e8b02e Python Script launcher extended to accomodate Chams.
* New: In VLSISAPD, in Configuration, add a new priority level UserFile
    to distinguish between the system configuration files and the user's
    configuration files (which take precedence).
* New: In Hurricane, in Script (Python), improve the API to be able
    to support Chams (and remove the duplicate capability from it).
      Add separate functions to perform the initialize/run(s)/finalize
    cycle step by step.
* Change: In CRL Core, rename real technology <hcmos9> to <hcmos9gp>,
    it's offcial name from CMP/ST. This is the 130nm.
      Move the reading of the symbolic & real technologies names from
    coriolisInit.py to helpers.__init__.py, to be shared with
    chamsInit.py.
      To avoid a clash of names inside of helpers, the two variables
    of techno.py are renamed "symbolicTechnology" and "realTechnology".
      Move python init system from crlcore/src/crlcore to crlcore/python.
* New: In CRL Core, In Utilities, add site-packages/pharos to the
    PYTHONPATH.
* Change: In Kite, move python init system from kite/src/init to
    kite/python.
2015-03-17 16:31:24 +01:00
Jean-Paul Chaput 8566126acc Adding Configuration support to Etesian.
* Change: In Bootstrap & ccb, the coloquinte project is renamed into
    "importeds", it will be the home of all the externally
    devellopped softwares that are needed to build Coriolis.
      Add explicit support for Fedora ("Linux.fc") and uses
    site-packages, as everybody else.
* New: In CRL Core, in etc/, adds the configuration files for Etesian.
* New: In Etesian, activate the Configuration object. Now uses it's
    own configuration variables instead of borrowing those of
    Nimbus & Mauka.
* Change: In Documentation, updated User's Guide to present Etesian
    as the placer, instead of Mauka.
* Change: In Cumulus, slight change in ClokTreePlugin and ChipPlugin
    to match the new Etesian/Python interface.
2015-02-27 18:16:03 +01:00
Jean-Paul Chaput 3b343f08cf Bug in Python proxy deallocation. Update to latest Coloquinte.
* Bug: In Bootstrap, in coriolisEnv.py, check if devtoolset-2 is already
    active before launching it as a sub-shell.
* Bug: In Isobar, In PyHurricane.h, DBoDestroyAttribute() set the proxy
    pointer toward the C++ object to NULL. So when the Python object is
    deleted no double-deletion occurs on the C++ object.
      Add some more trace information in Python link/dealloc.
* Change: In CRL Core, in cyclop, make CMakeLists.txt automatically
    choose the right rule for linking the binary wether we use Qt 4 or
    Qt 5. Very irksome problem.
* New: In EtesianEngine::addFeed(), do not take into account instances
    that are not placed entirely inside the top cell abutment box (was
    causing a core dump).
* Bug: In Katabatic, in GCellQueue, correct a mismatch between a GCell
    set and the iterators used upon it.
* Bug: In Mauka, in Row & Surface correct a mismatch between a container
    and it's iterator.
* New: In Etesian, updated to work with the latest Coloquinte, patch
    contributed by G. Gouvine.
      Added EtesianEngine::setDefaultAb() to compute an abutment box if
    the Cell is completly unplaced.
* New: In cumulus, in ClockTree, now the placer can be configured to be
    either Mauka (slow simulated annealing) or Etesian (fast analytic).
    New setting 'clockTree.placerEngine' in plugin settings.
2015-02-13 23:38:55 +01:00
Jean-Paul Chaput b18219d807 Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
    The sub-directory name is 'el7_64'.
      In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
    store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
    more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
    The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
    display threhold of the layer. This way we can adapt to different
    standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
    cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
    and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
    Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
    tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
    doing it (or not).
2015-02-01 23:24:13 +01:00
Jean-Paul Chaput ae4d938553 Buffer cell configuration in ClockTree. More config parameters in Chip.
* New: In ClockTree plugin, select the name of the buffer cell through
    configuration (parameter: "clockTree.buffer"), and guess the I/O
    name of this buffer automatically.
      Put configuration parameters in plugin.conf and not mauka.conf.
      Bug: strangely triggers a coredump in components collection
    when used with <vsxlib>. Some debug printing still active until
    that is solved.
* New: In Chip plugin, make the size and numbers of the block rails
    configuration parameters (in plugin.conf).
2014-09-02 11:17:47 +02:00
Jean-Paul Chaput 2a1c7e181e Express "xEdgeCapacity" ratio as "xTracksReservedLocal" a number of tracks.
* Change: In Kite, Katabatic & Knik, express the number of tracks truly
    available to the global router by the number of tracks reserved to
    the local routage inside a GCell. Replace the ratio parameter
    "hEdgeCapacity" by an integer parameter "hTracksReservedLocal"
    (duplicate for verticals).
      It is more explicit to give directly the number of tracks that
    are to be used locally, and potentially saves us from rouding
    problems when calculating the number of availables tracks.
      Note: we cannot do that for the layer saturateRatio as it
    uses the density ratio that take account local wires, leading
    to fractional results.
* Change: In Katabatic, in <GCellGrid>, rename checkEdgeSaturation()
    into checkEdgeOverflow(), more explicit.
* Change: In Knik, in <Graph>, display the computed capacities of the
    lower left node edges (should be the same througout all the grid).
* Change: In Unicorn, in <cgt.py>, uses the new parameters names for
    edge density.

Jean-Paul Chaput db4c811d75 Added a common configuartion part for kite.conf (containing the layout) 2014-05-26 14:22:19 +02:00
Jean-Paul Chaput 8bc7bd38db Add a common/ to share the trunk of symbolic technologies configurations.
In CRL Core configuration files, "display.conf", "patterns.conf" and
"technology.conf" share most of their code. So that common part is put
into "common/" and sourced from the final configuration file.
Update the documentation according the the new initialization scheme.
