Jean-Paul Chaput 087ef239c2 Add support for Antenna/Diode insertion in Etesian.
* New: In Etesian::Configuration add new parameters for antenna
    effect management:
    * "etesian.diodeName"    : the name of the diode cell.
    * "etesian.antennaMaxwl" : maximum length above which antenna
         effect can occur. Must be the maximum for all the normal
	 routing layers.
    * "etesian.antennaInsertThreshold" : during the placement steps,
         threshold for linear disruption at which we will look for
	 the RSMT and insert diodes.
* New: In EtesianEngine::antennaProtect(), at a designated point
    in the placement iteratives step, when the spreading starts to
    be significant enough estimate the RSMT length and add a diode
    if need be. The diode will be put side by side with the driver
    cell. This is done by enlarging the driver cell of the diode
    width.
* New: In EtesianEngine::_updatePlacement(), in the final stage,
    modify the netlist to connect the diode. The diode will be
    put on the side of the cell closest to the driver. This may
    alow to make the connexion directly in METAL1 in the future.
* Change: In etesian/Placement.cpp, make the whole placement
    structure a persistent attribute of the EtesianEngine so
    it can be used afterwards.
      Add a post-placement diode insertion feature. Finally
    unused as they are added on the fly during placement.
      In the Area, add data about the diode tie in the TieLut.
* Change: Add EtesianEnginea::clearColoquinte(), to keep the
    post-placement structure while purging the Coloquinte one.
* Change: In cumulus/plugins.block.block, keep the Etesian engine
    until the whole P&R is done, so we potentially can exploit
    the post-placement datas.
* Bug: In cumulus/plugins.chip.power.GoCb(), for the METAL1 power
    and ground wires coming from the standard cell, it was assumed
    they where made of Horizontal segments, this is not the case
    in FlexLib... So force to consider the plane as Horizontal when
    we are processing that plane.
      Better solution should be to use Horizontals...

Jean-Paul Chaput 405ca8d11b Improved support for LibreSOCIO (real), use IOPadIn & IoPadOut. 2020-12-27 12:46:04 +01:00
Jean-Paul Chaput 57432bbb50 * Bug: In cumulus/plugins.chip.configuration, check that the core
height is a multiple of sliceHeight. Otherwise, in some situations,
    fixed cell may peek out of the placement area, triggering
    Coloquinte assert (which says that the top of the cell is *above*
    the top row).

Jean-Paul Chaput e3803d28d7 Simple HFNS (#4), break the net, regardless of placement.
* New: In cumulus/plugins.block.hfns4.py, perform simple HFNS by breaking
    the net into sub-nets of at most 10 sinks (hard-coded for now).
      As this method is called *after* the netlist as been virtually
    flattened, we have to create the RoutingPad at the top level
    ourselves. Sub-nets are created at the Cell top-level (same
    approach as for clock synthesis, because there is no smart way
    to guess where they should be).
* New: In cumulus/plugins.block.block.py, perform HFNS (#4) *before*
    doing placement. To see the real sink count on each net, we must
    perform the virtual net flattening first (Cell::flattenNets()).
* Change: In cumulus/plugins.block.configuration, allow the creation
    of spare buffer in any cell (instead of only "self.cellPnR").
* Change: In cumulus/plugins.block.spares.Spares.raddTransNet(),
    Check if intermediate masterNet exists in Cells before trying
    to blindly re-create it.
2020-12-27 12:38:01 +01:00
Jean-Paul Chaput 8fdaf47f3d Second attempt at tie insertion. Works, but disturb placement.
* New: In Etesian::Configuration, added "etesian.lacthUpDistance" to
    control tie cells insertion (for polarization contacts).
* New: Etesian/Placement as a complete replacement for FeedCells.
    Rebuild the complete slicing structure of the placement to
    serve as a building block for post-placement changes under
    Coriolis. Currently used to regularly insert body ties.
      This is not optimal as we displace cells in each slice in
    a non-coordinated manner.
* New: In cumulus/plugins/block.configuration.FeedsConf, register
    the "etesian.latchUpDistance" parameter. Provides the tie width.
* New: In cumulus/plugins.block.spares, add ties around the buffer
    pool block and "cap ties" at both end of each slice.

Jean-Paul Chaput 172bdd9240 First attempt at inserting bulks, fail.
* New: In cumulus/plugins.block.spares, added creation of vertical
    stacks of feed cells, for their N/P tie contacts, to ensure
    correct bulk polarization. Fail, because the placer cannot
    cope with such massive obstacles, the vertical columns are
    too close to manage.
* New: In cumulus/plugins.block.configuration, add support to
    FeedsConf so lone instances can be created (for the first
    bulk trial).
2020-12-09 00:15:30 +01:00
Jean-Paul Chaput 945b9a24fa Fix I/O Pad ring 45 degree corners where off the foundry grid.
* New: In CRL/hepers, new function onFGrid() to ensure a DbU is on the
    foundry grid. Rounding is always done to the inferior integer.
* New: In CRL/GdsDriver, added a set of isOnGrid() functions to check
    that all coordinates of various objects are on the foundry grid.
      Use isOnGrid() in most objects processed in
    GdsStream::operator<<(Cell*).
* Bug: In cumulus/plugins.chip.pads.Corner, correctly round the
    coordinates of the 45 degree segments so they are still on the
    foundry grid.
2020-12-09 00:05:52 +01:00
Jean-Paul Chaput 973cc0f3c3 In LibreSOCIO, allow to choose between complete/abstract layout.
* New: In cumulus/plugins.core2chip.libresocio.CoreToChip, use new
    configuration variable "chip.useAbstractpads" to select between the
    abstract version (GPIO, VDD, ...) and the full version (IOPadInOut,
    IOPadVdd, ...) layout.
2020-12-07 16:41:09 +01:00
Jean-Paul Chaput 564714d73e Set a maximum wire with for LibreSOCIO I/O pads to corona wires.
* New: In cumulus/plugins.chip.pads.Corona._createCorewire(), add an
    hard-coded limitation for LibreSOCIO I/O pad to corona wires to
    always be below the maximal threshold.
2020-12-07 16:39:36 +01:00
Jean-Paul Chaput 51028980c9 Modify the chain of "save()" calls in chip/block to pass on flags.
* Change: In cumulus/plugins.block.configuration.BlockConf.save(),
             cumulus/plugins.block.Block.save(),
             cumulus/plugins.chip.Chip.save(),
             cumulus/plugins.core2chip.core2chip.CoreToChip.buildChip(),
    Add a "flags" parameter to control the way logical views (aka "vst")
    are saved. Mainly allowing to pass on the VstUseConcat option in
    order for Alliance tools to be able to read them back (lvx, asimut).
* Change: In cumulus/plugins.core2chip.core2chip.CoreToChip.buildChip(),
    don't stop at the first I/O pad signal missing on the core, but
    display all the missing ones (LKCL proposal).
2020-12-05 11:59:48 +01:00
Jean-Paul Chaput 1411739c0b Make block/chip plugin use the common rsave plugin.
* In cumulus/block.configuration, the rsave method was buggy. It did stop
    it did not save "terminal" master cells (i.e. a cell without instance)
    instead of "netlistTerminal" (explicitely flagged for standard cells).
      The result was that some "empty netlist" in the complete "ls180"
    from LibreSOC went missing. Causing cougar to complain.

Jean-Paul Chaput 78823b17c1 Transfer of blif2vst.py & yosys.py from alliance-check-toolkit. 2020-11-27 18:47:19 +01:00
Jean-Paul Chaput 85d943a3e4 Added support for JSON pinmux reading from LibreSOC.
* New: In cumulus/plugins.blocks.iospecs.IoSpecs, new class to manage
    I/O pads placement. Support for reading the JSON pinmux format
    (courtesy of LKCL & StackOverflow).
2020-11-27 18:46:58 +01:00
Jean-Paul Chaput 13726d648b Better/nicer management of the BigVia in cumulus.
* Change: In cumulus/plugins.block.bigvia.BigVia, center the VIA cut
    matrix. Issue a BIG warning when no one cut could be drawn
    (temporarily disabled until I fix the corona).
2020-11-25 21:52:48 +01:00
Jean-Paul Chaput 29b57e86e5 DRC correct on Arlet6505 / TSMC C180.
Integrate new features and bug fixes so the Arlet 6502 benchs successfully
passes real DRC with reference industrial tools. Short summary:
* Manage minimum area for VIAs in Katana::Tracks.
* Allow different wire width for wires perpandicular to the prefered
  routing direction.
* StackedVIAs used in the clock tree no longer assume an uniform
  routing grid (same offset & pitch all the way up).
* Some hard-coded patches in PowerRails for FlexLib.

* New: In CRL/symbolic/cmos/kite.py & cmos45/kite.py, update the
    RoutingLayerGauges by adding the new PWireWidth parameter.
    Always zero in case of symbolic layout (too fine tuning).
* New: In CRL::RoutingGauge, add accessor to PWireWidth parameter.
    Modify the clone method.
* New: In CRL::RoutingLayerGauge, add new parameter "PWireWidth"
    to give the width of a wire when it not drawn in the prefered
    routing direction. If it is set to zero, the normal width is
    used.
* New: In CRL::PyRoutingGauge, export the updated constructor
    interface. It is *not* backward compatible, one must add the
    PWireWidth parameter in the various kite.py configuration
    files (in etc/).
* Change: In AnabaticEngine::_gutAnabatic(), disable the minimum
    area detection mechanism, replaced by a more complete one in
    Katana::Track. Left commented out for now, but will be removed
    in the future.
* Change: In Anabatic::AutoContact::updateLayer(), now systematically
    calls setLayerAndWidth() to potentially resize the VIAs. This is
    needed in real mode as VIAs are *not* macro-generated but have
    their real final size.
* Change: In Anabatic::AutoContact::setLayerAndWidth(), select the
    width and height of the contact using the gauge wire width *and*
    perpandicular *wire width*.
* Change: In Anabatic::AutoSegment::_initialize(), the "VIA to same cap"
    to PWireWidth/2, this will be the size of the VIA in the
    non-preferred direction at the end cap (non-square in real mode).
* Change: In Anabatic::AutoSegment::getExtensionCap(), makes different
    cases for symbolic and real. Use raw length in real, add half the
    wire width in symbolic.
      Add a flag to get the extension cap *only*, not increased of
    half the minimal spacing.
* Change: In Anabatic::AutoSegment::bloatStackedStrap(), enhanced,
    but finally unused...
* New: In Anabatic::AutoSegment::create(), use the PWireWidth when
    the segment is not in the preferred routing direction (and of
    minimal width).
* New: In Anabatic::Configuration, add new getPWirewidth(),
     DPHorizontalWidth() and DPVerticalWidth() accessors.
* Change: In AnabaticEngine::setupPreRouteds(), skip components in
    in "cut" material. We are only interested in objects containing
    some metal (happens in real mode when VIAs cuts are really there).
* New: In Katana::PowerRailsPlanes::Rail::doLayout(), add an hard-coded
    patch that artificially enlarge the *wide wire* so the spacing for
    wide wire is enforced. For now, two pitches on each side for
    "FlexLib" gauge.
* New: In Katana::Track, add support to find and correct small wire
    chunks so they respect the minimum area rules.
      Two helper functions:
      * ::hasSameLayerTurn(), to find if a a TrackElement as non-zero length
        perpandicular is same layer connected to it.
      * ::toFoundryGrid(), to ensure that all coordinates will be on the
        foundry grid (may move in a more shared location).
      * ::expandToMinArea(), try to expand, *in the routing direction*
        the too small wire so it respect the minimal area. Check for the
	free space in the track.
    Track::minExpandArea() go through all the TrackElements in the track
    to look for too small ones and correct them.
* Change: In Katana::RoutingPlane, add an accessor to get the tracks.
* New: In KatanaEngine::finalizeLayout(), add a post-treatment to find
    for minimal area violations.
* Change: In cumulus/plugins.block.configuration.GaugeConf, add a
    routingBb attribute that will serve as a common reference to all
    the functions calculation track positions. We must not have two
    different reference for the core and the corona. The reference
    is always the corona when we working on a complete chip.
* New: In cumulus/plugins.block.configuration.GaugeConf.getTrack(),
    Simplified and more reliable way of getting tracks positions.
    Use the routingBb.
* New: In cumulus/plugins.block.configuration.GaugeConf.rpAccess(),
    Make use of getTrack() to get every metal strap on the right
    X/Y position.
* New: In cumulus/plugins.block.configuration.GaugeConf.expandMinArea(),
    As those wires are left alone by the router, it is our responsability
    to abide by the minimal area rule here. Hence the code duplication
    from the router (bad).
      Mainly wires made for the clock tree, I mean.
* Bug: In cumulus/plugins.chip.configuration.ChipConf.setupICore(),
    the core instance must be placed on the GCell grid, defined by the
    slice height (X *and* Y).
* Bug: In cumulus/plugins.chip.corona.Builder(), forgot to use bigvia
    for the corners of the inner ring.
* Bug: In cumulus/plugins.chip.pads.corona._createCoreWire(), hard-coded
    patch for LibreSOCIO, the power/ground connectors toward the core
    are too wide and can create DRC errors when put side by side.
    Shrink them by the minimal distance.

Jean-Paul Chaput 73b019a156 Fix a slight shift between pad instances and their ring wires. 2020-11-16 00:58:40 +01:00
Jean-Paul Chaput b974795a44 Generate cut via matrixes instead of monolithic symbolic ones.
* New: In cumulus/plugins/chip.corona.HorizontalRail & VerticalRail,
    use the new BigVia instead of StackVia to generate a matrix of
    cut when in real mode. Stick to the one massive VIA when in
    symbolic.
* New: In cumulus/plugins/block.bigvia.BigVia to generate matrixes
    of cut VIA.
2020-11-14 18:53:51 +01:00
Jean-Paul Chaput acc9405ba3 Added support for real LibreSOCIO pads.
* New: In cumulus/plugins.block.configuration, added class ConstantsConf
    to store information and create instances of "zero" and "one" cells.
    Added attribute in BlockConf class.
* Change: In cumulus/plugins.block.configuration, moved the cell cloning
    and saving from block.spares.Spares to configuration.BlockConf as
    it is a service that can be used by other modules than just spares.
    Other modules may modificate the netlists also, like in XXXX.
* Change: In cumulus/plugins.chip.configuration, in various methods,
    manage both cases when the layer is symbolic or real (difference
    in accessing the underlying BasicLayers).
* Change: In cumulus/plugins.chip.configuration, less clutered display
    of lambda length in trace mode (and use of 'L' as 'l' was too close
    to '1').
* Bug: In cumulus/plugins.chip.corona.VerticalSide.addBlockages(),
    as the clock are now on the *inner* rail(s), blockage must be on
    the *outer* rails (power lines).
* New: In cumulus/plugins.chip.pads.Corner, add support for 45 degree
    corners (cfg setting "chip.use45corners").
* New: In cumulus/plugins.chip.pads.Side.check(), correct computation
    of the side's length. Was using the ioPadStep instead of the pad
    cell width!
* Change: In cumulus/plugins.chip.pads.Corona._padAnalysis(), LibreSOCIO
    pads uses Verticals for their ring wires (common sense would want
    them *Horizontal*). So they must be included in the physical pin
    detection, but in turn this cause havoc in pxlib... So create a
    filtering according to the library name. This is *not* robust
    but will do for now.
* New: In cumulus/plugins.chip.pad.core2chip.CoreToChip, rename
    self.state into self.conf for clarity.
      New method newEnableForNet(), to create "enable" nets on the
    fly for emulated In/Out pads.
      As it can edit the netlist (new "enable" nets) call the
    BlockConf.rsave() method instead of direct saving through
    AllianceFramework.
      Raise NotImplementederror instead of ErrorMessage.
* New: In cumulus/plugins.chip.pad.core2chip.IoPad.createPad(),
    on emulated In/Out I/O pad like for LibreSOC, generate on the fly
    the right enable signal.
      If an enable signal is given, it will be used (backward
    compatible with the previous behavior).
* New: In cumulus/plugins.chip.pad.core2chip, support for real
    LibreSOCIO pads in libresocio.py module.
2020-11-11 14:29:56 +01:00
Jean-Paul Chaput 541b23216c Support of FlexLib I/O in Core2Chip & chip plugins (alpha).
* New: In cumulus/plugins/core2chip/, support for the FlexLib I/O cells
    symbolic abstracts ("niolib"). More flexible way of specifying the
    number and positions of the various power pads, both I/O power and
    core power.
      For niolib (FlexLib I/O abstract), support for multiple clocks,
    that is, clock become ordinary pad (with signals typed as CLOCK).
* New: In cumulus/plugins/chip/, added support for niolib and final
    integration of multiple clocks (only for niolib).

Cleanup & error messages in cumulus/plugins/alpha/.
2020-10-25 12:08:48 +01:00
Jean-Paul Chaput b9f2a5bf28 Remove unused buffers in Block & Core2Chip.
Note: The previous strategy was not fully coherent in chip mode.
      Everything added, net and components must be added at
      corona level and not separated between corona and core.

* New: In cumulus/plugins/block.configuration, new FeedsConf object
    to handle the feeds and provide a filling area helper.
* New: In cumulus/plugins/block.spares.removeUnusedbuffers() to
    remove unused buffers in the pools and replace them by feedthrough.
* Change: In cumulus/plugins.block.spares, unify coordinate/slice
    computation. If we are in chip mode, the coordinates are
    expressed in the corona *but* aligned on the slices of the
    *core* model.
* Change: In cumulus/plugins.block.Block.rsave(), add the '_r' suffix
    to the routed cells.
* Change: In cumulus/plugins.clocktree.ClockTree, when in chip mode
    create everything at corona level. Also forgot to set type of
    clock subnet as clock.
2020-10-23 22:28:42 +02:00
Jean-Paul Chaput f7ba17213d In cumulus/Chip plugin Check that the spare side is not too small.

Jean-Paul Chaput 3d33c4e66a Port of the chip P&R plugins into Alpha.
Note: The port is not complete. Integration of LKCL patches will
      follow shortly.

* Change: In cumulus/plugins/alpha/block, more simple inheritance
    scheme. Use classic inheritance instead of @classdecorator.
    BlockConf (renamed from BlockState) now inherit from GaugeConf,
    Double inheritance tree, for Block/Chip and BlockConf/ChipConf.
    Allow an uniform syntax for configuration parameters.
* New: In cumulus/plugins/alpha/chip, port of the chip plugin and
    integrate with the block plugin. It is now a derived class of
    Block. ChipConf is also a derived from BlockConf.
      Obsolete "./coriolis2/ioring.py", all informations are given
    though the ChipConf state class.
* New: In cumulus/plugins/alpha/core2chip, only Alliance/pxlib is
    ported yet.
2020-10-14 15:26:46 +02:00
Jean-Paul Chaput 513bc72541 Port & integration of core2chip into alpha/block.
* New: In CRL/helpers/utils.py, create a Python "class decorator".
    Works like a decorator but without the need of implementing
    the Concrete/Abstract classes structure Design Pattern.
      Create proxies in the derived class for the base class
    attributes & methods.
* Change: In cumulus/plugins/alpha/block/configuration.py, enrich
    the BlockState object to support core2chip parameters. Make it
    even more autonomous from the Block class.
* New: In cumulus/plugins/alpha/core2chip, port of the core2chip plugin
    and integration with the alphs/block plugin. At "constant features"
    as a first. Only ported "cmos", phlib will be later.

Jean-Paul Chaput 3495536268 Third variant for HFNS, trunks mades with Steiner tree (FLUTE).
Note: Keep the various hfnsX.py as toolboxes for future experiments.
* New: cumulus/plugins/block/hfns3.py, build the trunk of the
    net as a RMST. First with the "Iterative One Steiner Point"
    (terribly slow above 100 points) then with FLUTE.
      For the global routing trunk, must be very cautious to
    check that the cluster "graph point" is the one of the
    it's buffer RoutingPad so both end up in the same GCell.
* New: cumulus/plugins/block/timing.py, stub for basic
    timing computation and conversion between sink and
    capacitance. Currently based on the fake 350nm given as
    example in SxLib ("man sxlib"...).

Jean-Paul Chaput ea94175eb4 In Entity, add Python bindings for "isBound()" and "getId()". 2020-09-30 11:50:09 +02:00
Jean-Paul Chaput 0c1a6def56 Basic implementation of High Fanout Net Synthesis.
To perform HFNS, recursively makes clusters of closest sinks, less than
30 sinks and with a control of the half-perimeter at all the clusters
levels. Clearly needs lots of improvements but the backbone of the
feature works. Make use of the pool buffers as do the clock tree.
Clustering is done with a degenerated Kruskal algorithm.

This is rougly based on the article:

2020-08-12 22:55:29 +02:00
Jean-Paul Chaput 51e3639687 Added multiple clock support in cumulus/plugins/alpha/block.
* New: Added multiple clock support in H-Tree generation in alpha/block.
* New: In CRL/etc/<NODE>/<TECH>/plugins.py, added three new parameters
    for block plugin config:
      "block.spareSide" : The size of the minimum side of a buffered area.
                          (quad-tree leaf).
      "spare.buffer"    : The model of the cell buffer to be used.
      "spare.maxSinks"  : max number of sinks on a buffer before issuing
                          a warning (non-blocking).
* Bug: In Etesian::BloatCell::getAb(), never apply the bloat profile to
    fixed cells. In case of buffers from the spare maxtrix it was leading
    Coloquinte to detect an overlap of fixed cells, which it do not
    support (rightly so).

    a layout, that is, is already placed & routed, it's instances must
    be flagged as FIXED instead or PLACED so Etesian will really sees
    them as unmovable and don't account them to be placed.

Jean-Paul Chaput f3dd4bcd31 Fixes cumulus recursive save plugin.
* Bug: In cumulus/plugins/rsave.py, use "Cell.isTerminalNetlist()"
    instead of "Cell.isTerminal()" to find the hierarchical stop
    points.
      If the root cell to be saved is itself a *terminal netlist*
    one, save it anyway. The top level *must* be saved regardless to
    it's status.

Jean-Paul Chaput 5d891b2cd8 The VST driver is now allowed to preserve the case of identifiers.
* New: In CRL::NamingScheme, add a flag VstNoLowerCase, and its
    management it in the Verilog to VHDL converter.
* Change: In CRL::BlifParser::Model::toVhdlModels(), disable the
    lowercasing of identifiers. We shouldn't apply Alliance VHDL
    subset constraits when reading blif files. So we will see
    uppercase identifiers in Coriolis.
* Change: In CRL::VstParser, no longer lowercase identifiers that
    are *not* VHDL keywords. Uppercases are legals in VHDL...
* New: In CRL::Catalog::State, add a new flag VstNoLowerCase to
    tell if the VST driver should keep the uppercases.
* Change: In CRL::VhdlEntity, add a VstNolowerCase flag to disable
    the lowercasing.
* Change: In CRL::vstDriver, lower case the file name if needed.
    remove the previously opened filename if it differs from the
    lowercased one.
* Change: In UnicornGui CTOR, disable VHDL enforcement for the
    Blif parser.

    matrix-like netlists placement. This plugin is configured *ONLY*
    for Libre-SOC FU-FU matrix 30x30.
2020-06-06 12:16:51 +02:00
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).
2020-04-27 10:34:19 +02:00
Jean-Paul Chaput a50b6ce317 More PEP8 compliant Python code. Start rewrite Python/C++ wrappers.
* Change: In CRL/helpers, cumulus/plugins, oroshi & karakaze,
    Move towards more Python PEP8 compliance:
      * All indentations sets to 4 spaces (in progress).
      * In plugins, remove messages about software collections
        and RHEL (too many case could wrongly lead to that).
	Instead systematically uses "helpers.io.catch()".
      * Put in lowercases all modules names. Note that C++ exported
        modules *keep* their Capitalized names (to preserve the
	identity with the C++ namespace).
      * When making import, use full path.
      * Rename the run function from "ScriptMain()" to "scriptMain()".
* Cleanup: In CRL/etc, remove obsoleted configuration files,
    the one ending in ".conf". Keep those who have not been ported
    to the new style yet.
* New: In Hurricane/src/configuration, first trial at replacing the
    C preprocessor macros by C++ templates. Applied first to configuration
    from VLSISAPD.
      This is unfinished business, just a limited demonstrator for now.
      It is installed as a separate Python library "Cfg2" which do not
    interact with the rest of Coriiolis.
      The end goal is to fully remove boost and merge VLSISAPD useful
    components directly inside Hurricane.
2020-04-08 11:24:42 +02:00
Jean-Paul Chaput dfe4d80b60 Clarify semantic of flatten Collections (walkthrough).
In the Cell/Instance hierarchy, the "terminal" and "leaf cell" concepts
where not clearly defined and partially overlapping. Now, "Terminal" is
the refer to the physical hierarchy (layout) and "TerminalNetlist" to
the logical hierarchy (netlist). The logical hierarchy can be less deep
than the physical one thanks to a Cell dedicated cell flags. Collections
related to the physical hierarchy keep their old names, the one related
to the logical hierarchy are renamed from "Leaf" to "TerminalNetlist".
The name "Leaf" was too ambiguous (leaf for *what* hierarchy).

* Change: In Hurricane::Device, set the "TerminalNetlist" flag once and
    for all. No need set it in all the derived classes again.
* New: In Hurricane::MultiCapacitor, added new parameter "dummy" to
    create dummies around the capacity matrix.
* Change: In Hurricane::Cell, remove "Leaf" related methods, replace
    them by "TerminalNetlist" one, especially Collections. Now we have
    two clear sets of Collections to walkthough the layout or the
    netlist.
      Change the "Terminal" flag into "TerminalNetlist".
* Change: In Hurricane::CellCollections, rename "Leaf" into
    "TerminalNetlist" collections and apply the new semantic to the
    locators.
* Change: In Hurricane::DataBase, Leaf to TerminalInstance renaming.
* Change: In Hurricane::DeepNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::HyperNet, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Instance, Leaf to TerminalInstance renaming.
* Change: In Hurricane::Viewer::HierarchyInformations, Leaf to
    TerminalInstance renaming.
* Change: In CRL::AllianceFramework, Leaf to TerminalInstance renaming.
* Change: In CRL::Catalog, Leaf to TerminalInstance renaming.
* Change: In CRL::ApParser, Leaf to TerminalInstance renaming.
* Change: In EtesianEngine::AddFeeds, Leaf to TerminalInstance renaming.
* Bug: In EtesianEngine::resetPlacement, move there the loop over
    non terminal netlist instances to flag fully placed sub-blocks
    as terminal for the netlist. Only then remove the feed cells
    from unplaced instances. Previously, the feed cells where stripped
    even from already placed instances.
* Change: In Katana, Leaf to TerminalInstance renaming.
* Bug: In Bora::PyDSlicingNode, allow the range parameter to be the
    Python None object when we do not want to pass one but need to
    have it as positional parameter.
* Change: In Cumulus/clocktree/ClockTree.py, Leaf to TerminalInstance
    renaming.
2020-03-10 12:10:53 +01:00
Jean-Paul Chaput 757b95343b Support for full Database clear & restart.
* New: In CRL/etc/node600/phenitec, ported configuration of Phenitec 0.6um
    Compliant with DataBase reset.
* New: In CRL/python/helpers, added function "unloadUserSettings()" to
    unload Python modules prior to a full reset.
      Added "resetCoriolis()" to perform full DataBase reset.
* Change: In CRL::AllianceFramework, make it a derived class of DBo so
    the destroy() is now provided.
* Bug: In CRL::AllianceFramework::getCell(), do not attempt any load if
    the library list is empty. Should never occur except in case of a
    botched databse reset.
* New: In CRL::AllianceFramework, new method "saveCATAL()" to write back
    the catalog of a library and "saveCells()" to write back the cells.
      Note: only cells actually loaded in memory will be write back.
* New: In CRL::Catalog, add method "saveToFile()" to write back the CATAL
    of a library.
* Change: In CRL::ParserDriver, replace "const string&" by "string"
    (improved string support of the GNU STL).
* Change: In CRL::ParserSlot, use string instead of Name.
* Change: In CRL::ApParser, make _layerInformation an ordinary attribute
    instead of a static one. This allow for it's correct resetting
    across databas resets.
* Change: In CRL::VstParserGrammar, reinitialize Vst::framework at each
    parser call. Needed to support database reset.

* New: In Hurricane::DBo, add an object counter to be sure that when
    we perform a reset, no remaining DBo is allocated. This is different
    of the object id which is ever increasing.
      Note that, at reset, we check against "1" remaining element as at
    this point only Database is still allocated.
      Add a new "resetId()" method. MUST NEVER BE CALLED except by
    DataBase::_preDestroy().
* New: In Hurricane::Database, new clear() method to remove the Cells
    of all the libraries in reverse hierarchical depth order.
    Make use of the new CellsSort class.
* Change: In Hurricane::DataBase::_preDestroy(), call "clear()" and
    DBo::resetId().
* Change: In Hurricane::Breakpoint, change the default callback to be
    a static function. So we can restore it later.
* Bug: In Hurricane::Instance::_preDestroy(), there was yet another
    loop of deletion over a collection for the shared pathes.
      Replace it by the repetitive deletion of the first element.
* Bug: In Hurricane::Net::_preDestroy(), RoutingPads must be destroyed
    prior to any other component.
* New: In Hurricane::ColorScale, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::DrawingStyle, add a "qtFree()" method for freeing
    the Qt Brush, Pen & Color.
* New: In Hurricane::Graphics, add a "disable()" method to call the
    various "qtFree()" of the sub-objects.
2020-02-29 16:55:14 +01:00
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.
2019-12-15 19:28:54 +01:00
Jean-Paul Chaput 09eccacfee Various fixes for Katana::BloatProfile.
* Bug: In Katana::BloatProfile::FlatInstance for X & Y calculation of
    flattened instances reserse the order of transformation. We must apply
    the occurrence path transformation to the instance transformation,
    and not the other way around.
      Was causing the bug in SNX example.
* Bug: In Katana::BloatProfile::Slice::tagOverloadeds(), the underlying
    Gcell was not kept in synch with the instance. This was causing a right
    shift of the bloated area.
* New: In Katana::BloatProfile, add the selection of overloaded edges and
    failed nets.
      Add a flag to KatanaEngine::runGlobalrouter() to choose what failed/
    overloaded components to display (selectors).

Jean-Paul Chaput 68e45bc5ab Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
  1. Compliance with clang 5.0.1, tested with the RedHat collection
     llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
     with Xcode & macports. The bootstrap install system has been modificated
     accordingly.
  2. The basic support for routing density driven placement. Related
     features are:
     * Bloat property. Each Occurrence of an Instance can be individually
       bloated. This property not attached to any tool to allow the placer and
       router to share it as wanted. Nevertheless, it is defined in Etesian.
     * BloatProfile in Katana, add individual Bloat properties to Instances
       occurrences based on the East & North overflowed edges of each GCell.
     * Support in ToolEngine for a "pass number" of a tool. This pass number
       is mainly used to make "per pass" measurements. The MeasureSet system
       is improved accordingly to support multiple values of a same measure.
     * Embryo of "P&R Conductor" to perform the place & route loop until the
       design is successfully placed. May be the first brick of a Silicon
       Compiler.

* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
    the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
    instance occurrence BloatProperty dependency.
      Added option support for the "llvm-toolset-7" collection to build
    against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
    for first & second arguments must be called with <const T> and <const U>
    as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
    not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
    template has a static member "_name". Clang did show that the template
    for this static number has to be put inside the namespace where the
    template *is defined* (i.e. Hurricane) instead of the namespace where
    it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
    be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
    (clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
    signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
    (clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
    Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
    current working directory in the sys.path as in certain configuration
    it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
    encountering a RoutingPad on a top-level Pin Occurrence. The segment
    was generated in the wrong direction, creating DRC violations on the
    "mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
    Now, each kind of measure can accept multiple values put in a vector.
    The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
    indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
    addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
    name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
    that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
    was wrong, it was always returning true, which broke the "strick weak
    ordering" of the comparison.
      This was producing a core-dump in GCell::updateDensity() when sorting
    a vector<>. The end() iterator was being dereferenced, leading to the
    problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
    whose axis is perpandicular to the symmetry axis was wrong
    ("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
    and selectBloatedInstances() to automatically select segments from
    overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
    between global and detailed.
      Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
    driven placement.
2019-12-09 01:57:44 +01:00
Jean-Paul Chaput ef0f6f771a In Python scripts, if PyQt 4 fails to load, try PyQt 5.
* In CRL::Cyclop/CMakeLists.txt, add *again* the MOC files to the list
    of .cpp . Don't know what is happening here with MOC under Qt 5.
* In CRL/python/helpers.io, cleanly fails if neither PyQt 4 nor PyQt 5 is
    found. And tell it directly because this the module tasked to handle
    the exceptions/errors...
* In Cumulus/plugins/AboutWindow.py, try PyQt 4 then PyQt 5.
* In documentation/UsersGuide, now tells explicitely that Qt 4 must be
    used under RedHat 7 and Qt 5 under Debian.
2019-10-30 16:58:43 +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).
