Jean-Paul Chaput 17ecfd823b Enhanced techno rule support. Inspector support bug fix.
* Bug: In Hurricane/Commons.h, modify the getRecord<>() templates so
    that for both vector<Element> and vector<Element*>, the individual
    record created for each element are donne with pointers. That is,
    for the vector<Element> case, we take a pointer.
      As a general policy, except for the POD types, always use pointers
    or references to data in the records/inspector. Never uses values
    that can call the copy constructor.
      Suppress INSPECTOR_PV_SUPPORT() macro, keep only
    INSPECTOR_PR_SUPPORT().
      Provide value support only for getString<>() template.
      This value & copy constructor problem was causing a crash when
    trying to inspect Hurricane::AnalogCellExtension.
* New: In Hurricane::Technology, change the API of the PhysicalRule,
    now we can only create/get PhysicalRule, but setting the value of
    the rule itself must be done on the rule.
      Enhance PhysicalRule to provide for stepped rules, non isotropic
    and ratio rules.
      Merge TwoLayersPhysicalrule in PhysicalRule, much simpler to
    suppress the management of derived classes. That means that we
    loose a little memory as some fields are mutually exclusive.
    Not a problem considering that there will not be so many of thoses
    objects.
* New: In CRL/helpers.analogtechno.py, enhanced DTR support for rules
    like:
      ('minSpacing'  , 'metal1', ((0.4,20.0), (0.8,1000.0)), Length, 'REF.1')
      ('minEnclosure', 'metal1', 'cut1', (0.2,0.3)         , Length, 'REF.2')
      ('minDensity'  , 'metal1', 0.30                      , Unit  , 'REF.3')
      The DTR parser has been updated, but not the oroshi.dtr Rule
    cache for analog components. Given a rule name, the value used
    will be the horizontal one of the first step.
* Change: In hurricane/doc/hurricane, re-generate the documentation
    with updated support for Technology & PhysicalRule.

Jean-Paul Chaput 34c1795630 Support for long in CRL/overlay.Configuration.__setattr__(). 2020-07-14 19:55:20 +02:00
Jean-Paul Chaput 960e0cda18 In CRL::NamingScheme::vlogTovhdl(), remove '%' invalid VHDL character. 2020-07-14 19:53:34 +02:00
Jean-Paul Chaput 8ce2a7e318 In Etesian, do not reset the placement if we are using a sub-block.
* Bug: In EtesianEngine::place(), reset the placement *only* if we are
    *not* placing a sub-block *and* the top cell abutment box is empty.
* Bug: In EtesianEngine::place(), set the instance placement status of
    all intermediate instances to PLACED, so the AP driver will save
    them (we were having partially saved layout when using hierarchical
    designs).
* Bug: In EtesianEngine::resetPlacement(), reset the PLACED flag and
    the abutment box on the top cell or sub-block to be placed.
2020-07-14 19:51:01 +02:00
Jean-Paul Chaput e4041d5e26 Improved Hurricane/Python database reset.
* Change: In CRL/helpers/__init__.py, to ensure a complete restart of
    the database the __init__.py must be called again, but it's not the
    case with reload() (see Python doc). So helpers.resetCoriolis()
    must explicitly removes the Coriolis related Python modules from
    sys.modules (calling "del sys.modules[moduleName]").
      That list of Coriolis Python modules is built by calling
    helpers.tagConfModules(), it will tag all modules added to
    sys.modules since startup. It will remove (much) more than
    Coriolis modules, but that should be ok.
* Change: In CRL/etc/{node*,symbolic}/TECH/__init__.py, add a call to
    helpers.tagConfModules() for the techno modules to be erased on
    reset.

Jean-Paul Chaput 010fc79f4f Added rule minWidth_nWell to oroshi rule loader. 2020-06-30 14:54:42 +02:00
Jean-Paul Chaput 441cb71475 * New: In Anabatic::NetBuilder, to tackle once and for all the GCell
configurations for Libre-SOC manage up to 9 METAL1 terminals in
    1G to 4G configurations.
2020-06-30 10:00:29 +02:00
Jean-Paul Chaput 424b66e671 Added new GCell configurations to handle Libre-SOC test_issuer.
* New: In Anabatic::NetBuilder, some GCells configurations of Libre-SOC
    "test_issuer" (soclayout/experiments9) did have more METAL1 terminals
    than was though possible. Just added more entries in the connexity
    table for bigger numbers of METAL1. No new configuration was added,
    used the already existing ones.
2020-06-29 13:02:27 +02:00
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.
2020-06-26 17:13:52 +02:00
Jean-Paul Chaput b48f9b40b8 Fixes bad VHDL port map assignment for vectors in VST driver.
* Bug: In CRL/Vhdl::VectorPortMap::toVhdlPortMap(), two problems:
    1. Bad condition for the use of VstUseConcat. Must be used *only*
       when there is more than *one* mapped name.
    2. Missing case, when there is exactly *one* mapped name, that
       means that we have one full width vector to vector assignement.
       There may be another weakness here, for the portmap we assumes
       that both vector are mapped in the *same* direction (which is
       "downto" by our convention).
    3. In the "bit by bit mapping case" (every bits of the vector are
       differents bits), use the "signal + bit index" name instead of
       juste the signal name (i.e. full width).
    Solves the Libre-SOC/soclayout/experiment6/fpmul64 problem, now
    we can avoid the YOSYS_FLATTEN.
2020-06-26 17:13:18 +02:00
Jean-Paul Chaput b23f620c5d The VST driver may suppress linkage type.
* Change: In Vhdl:::Signal::toVhdlPort(), in Alliance VST signal with
    undefined directions are typed "linkage". This may not be compatible
    with vasy, so allow to replace them by "in".
* New: In CRL::Catalog::State, add a new flag VstNoLinkage to tell if
   the VST driver should not use the "linkage" type.
* Change: In Vhdl::Entity, add a VstNoLinkage flag to disable the use
    of the "linkage" type.
2020-06-24 23:27:21 +02:00
Jean-Paul Chaput 1ccb9c340f Add setters for space margin and aspect ratio in Etesian.
* Change: In EtesianEngine, add setters for space margin and aspect ratio.
    Export them in Python.
2020-06-16 21:39:10 +02:00
Jean-Paul Chaput b0a3bb33af Add early error detection for misaligned Pins.
* Change: In AnabaticEngine::checkPlacement(), add a check on all the
    external pins for preferred layer direction and routing grid
    alignement.
2020-06-16 21:38:21 +02:00
Jean-Paul Chaput 235a9eecea Adjustements to the ExceptionWidget behavior.
* Change: In Hurricane::ExceptionWidget,
    - Use a QTextLabel instead of a QLabel, make it "look like" a QLabel.
    - Always display using text mode. Not HTML (to preserve indentation).
    - Make the text of the error message selectable.
    - Make it resizable.
2020-06-16 21:37:18 +02:00
Jean-Paul Chaput 9c082230b5 Add forgotten asDouble() method to the Parameter interface.
* New: In vlsisapd/PyConfiguration, add asDouble() to the Parameter
    Python wrapper.
* New: In CRLCore/helpers/overlay, add support for float parameters
    in configuratuon.
2020-06-16 21:33:33 +02:00
Jean-Paul Chaput 09192ba084 Bug fix, check for unconnected signals in CRL::VectorPortMap::toVhdlportMap().
* Bug: In CRL::VectorPortmap::toVhdlPortMap(), unconnected bits where
    correctly checkeds for multi-bits vectors (both ordered and holed),
    but not for mono-bits connections (ONE bit of a vector).
2020-06-09 14:08:08 +02:00
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.
2020-06-08 13:34:25 +02:00
Jean-Paul Chaput f91fc4f927 Add experimental matrix placer into cumulus.
* In cumulus.plugins.matrixplacer.py, BETA plugins for getting back
    matrix-like netlists placement. This plugin is configured *ONLY*
    for Libre-SOC FU-FU matrix 30x30.

Jean-Paul Chaput f2a60768ca Export Entity::getId() to the Python interface. 2020-06-06 12:13:57 +02:00
Jean-Paul Chaput 7b1dab7742 Generate only one/zero cell in Blif parser.
* Change: In CRL::BlifParser, formerly, a zero/one cell was added for
    each vss/vdd direct connection, generating a huge flock of cells.
    Now only generate one per netlist.
      It can be discussed whether to old behavior is more desirable,
    it is a compromise between wire and area.
2020-06-06 12:13:29 +02:00
Jean-Paul Chaput ac04466090 Automatically try to load the layout of Terminal Cells.
* Change: In CRL::AllianceFramework::getCell(), if the Cell is marked
    as TerminalNetlist, then it may be a standard cell. So it's layout
    must be loaded. So now, systematically try to load the layout of
    netlist terminal cells.
2020-06-06 12:13:05 +02:00
Jean-Paul Chaput c6287c8d95 Correct Cell object detection while reading Oceane parameters.
* Bug: In karakaze/AnalogDesign.readParameters(), when asserting the
    type of dspec[0], it can either be a type (for analog devices) or
    a Cell object (*not* a type). So the issubclass may fails.
      Now check first if dspec[0] is an *instance* of Cell.
      This is an anisotropy in the type of the first element of
    the devicesSpecs table, but suppress one superfluous parameter.
2020-05-27 16:11:53 +02:00
Jean-Paul Chaput 4483766f34 Enabled support for track positionning in analog Transistor devices.
* New: In Analog, new Parameter derived class "StringParameter",
    to support strings. Also added to the Python interface.
* New: In Analog::Transistor, added StringParameters for specifying
    track positions. They are named "G.t", "S.t", "D.t" and "B.t".
* New: In Oroshi/wip_transistor.py, now read the track positionning
    devices parameters.
* New: In Karakaze/AnalogDesign.doDevice(), read an optional 14th
    parameter holding the track positions (example in ADC-SAR).
2020-05-11 15:59:45 +02:00
Jean-Paul Chaput 7dcd8e136a Suppress wrong errors/warnings in AnabaticEngine & AutoSegment.
* Bug: In Anabatic::AutoHorizontal & AutoVertical, in getGCells()
    method, do not display the "NULL GCell under" error message if the
    segment has just been created. It could on a "wrong" axis position
    so the line probing method may fail.
* Bug: In AnabaticEngine CTOR, if the "blockagenet" is created there,
    do not forget to set it's type to BLOCKAGE (to avoid later warnings).
* Bug: In Anabatic::NetBuilder::_load(), do not display a warning if the
    blockage net has no RoutingPads (it *must* not have one).
2020-05-10 17:09:33 +02:00
Jean-Paul Chaput faef4b182f Manage all devices in karakaze/AnalogDesign.readParameters().
* Change: In Karakaze/analogdesign/AnalogDesign.readParameters(),
    only Transistor and Capacitors where manageds. So when a devices in
    the dspec was from another type, it did issue an error.
      Now cleanly skip unsupported (yet) devices.

Jean-Paul Chaput b553aae8ad Correct icon sizing for normal definition display in BreakPointWidget. 2020-05-10 11:46:54 +02:00
Jean-Paul Chaput dc25159cd6 Bug fix, reset Cell flags after unrouting an analog design.
* Bug: In Bora::SlicingNode::clearGlobalRouting(), as we are unrouting the
    cell, the flags set up by Katana must be reset. The Cell is no longer
    "Terminal" and it's nets are "Un-flattened".
2020-04-30 00:38:32 +02:00
Jean-Paul Chaput bd4ace7cc8 Full update of the generated documentation. 2020-04-27 14:14:03 +02:00
Jean-Paul Chaput 2b4ee3abea Update docker config for Debian-10 / LibreSOC. 2020-04-27 14:11:44 +02:00
Jean-Paul Chaput 477c37643c Bug, In Session::_revalidateTopology(), iterate over an invalid vector!
* Bug: In Anabatic::Session::_revalidateTopology(), when iterating over
    _segmentInvalidateds, the vector can be modified. If it leads to a
    reallocation we end up on invalid iterators (using freed memory so
    sometimes with overwritten contents). Now, iterate with an index
    which warranty that we get a valid item at each iteration of the
    loop. And, of course, the vector is ensured to not shrink...
* Change: In Anabatic::Session::Session(), reserve (pre-allocate) at least
    1024 elements for all vectors. Mostly prevent the above bug and
    avoid constant reallocation.
2020-04-27 11:22:05 +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 e7bc4dc167 Bug fix, In Katana, do not remove AutoSegment conflicting with blockages.
* Bug: In Katana::NegociateWindow::createTrackSegment(), *fixed* AutoSegment
    in conflict with blockage where removeds. This was creating "holes"
    in the Anabatic articulated segment structure. Now just *don't*
    create the TrackSegment. Pass the regression tests, but not sure
    it is not generating problems elsewhere.
* New: AnabaticEngine::checkPlacement() to issue more clear errors about
    a defective placement.
2020-04-21 15:40:59 +02:00
Jean-Paul Chaput a4acb22e3c Bug fix, make the AP parser reentrant (NO static variables).
* Bug: In CRL::ApParser::_parseInstance(), the instance coordinates where
    stored in *static* variables (boo). Making the parser *not* reentrant.
    But in _parseInstance(), it can be recursively called through
    getCell() when an sub-instance layout was missing.
      Also make non-static all other variables in the various parser
    function.
2020-04-21 15:39:35 +02:00
Jean-Paul Chaput 0a664fed36 Support for multiple M1 connectors in GCells with M3 pins.
* Change: In Anabatic::NetBuilderHV(), in 2-3 globals plus one M3 pins,
    support up to 3 M1 connectors.
2020-04-20 20:53:49 +02:00
Jean-Paul Chaput 8978074fe7 Added new configuration in NetBuilderHV (for M3 Pins).
* New: In Anabatic::NetBuilderHV(), added configurations to manage
    one Pin M3 + one M1 terminal plus 2 & 3 globals:
      * _do_2G_1M1_1PinM3()
      * _do_3G_1M1_1PinM3()
    They were occuring for the first time in soclayout/experiment7
    in the "flat" approach.
* New: In Katana::runNegociate(), mark the newly routed netlist as
    "NetlistTerminal" so it is not placed and routed *again* when
    reused as an instance (mostly interract with Etesian).
2020-04-20 12:53:07 +02:00
Jean-Paul Chaput 010d9a3782 Clean policy of netlist (vst) and layout (ap) views recursive loading.
* Bug: In CRL::VstParserGrammar & VstParserScanner, when loading the
    instances models, we where loading both logical & physical views.
    This was causing cases of reentrency of the parser, with reset
    of the lexer static dictionary, leading to memory corruption.
      Now the identifiers are stored in the YaccState of each
    parsed cell and we only recursively call for the logical view.
* Change: In CRL::ApParser::_parseInstance(), recursively load the
    physical views as they are no longer loaded by the Vst parser.
* Change: In CRL::AllianceFramework::getCell(), sets the
    TerminalNetlist flag from the state (mode 'C' in CATAL) onto
    the cell.
* Change: In EtesianEngine::loadLeafcelllayouts(), new functions to
    load the layouts of the leaf cells if only the netlist has been
    loaded.
2020-04-17 11:28:47 +02:00
Jean-Paul Chaput 5a4d23f8fd Fix bad direction for segments in ApDriver.
* Bug: In CRL::ApDriver::DumpSegments(), reset the direction field to
    NULL between iterations so it is recomputed for each component and
    not keeping the first one ever guessed.
2020-04-15 10:42:38 +02:00
Jean-Paul Chaput 05c0907d5c Fix for Coriolis issue #6 (Katana core dump on ALU16).
* Bug: In Katana::AutoSegment::_preDestroy(), remove the segment from
    the source & target AutoContact cache.
      In LibreSOC/experiment7, weird placement caused fixed AutoSegment
    overlaping blockage to be deleteds. It seems to have never occured
    before (or at least, no ended up in core dump).
2020-04-15 10:41:46 +02:00
Jean-Paul Chaput 7e7e7170ba Improve symmetry management for analog designs.
* Bug: In Hurricane::NetRoutingState::getSymValue(), outrageously bad
    computation of the symmetric coordinate when the value was superior
    to the axis... (shame on me).
* Change: In Anabatic::Disjkstra::load(), for symmetrically paired nets,
    check that the axis of symmetry is *outside* the searchArea.
      Otherwise, the two mirrored areas overlaps and the two nets will
    unescapably be on top of each other. Issue a warning but still
    continue.
* Change: In Anabatic::Vertex::isRestricted(), allow perpandicular
    wire to go through struts or thin (less than one routing pitch)
    node. May have to recheck in the future and restrict to struts
    only.
* Bug: In Bora::HVSlicingNode::updateSymNetAxis(), rescursive call in
    child node was not systematically done (bad curly brace position).
      Also checks that symmetries are not empty before accessing the
    front element (one less core dump).
2020-04-10 12:15:23 +02:00
Jean-Paul Chaput 74e4544a55 Correct computation of H/W ratio in Bora (Igor Zivanovic).
* Bug: In Bora/SlicingDataModel, the division was done with integers,
    leading so there was a rounding *before* we casted to double.
      Now, use the BoxSet::getRatio() method and cast to double *before*
    dividing.
2020-04-08 15:09:20 +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 e9ce33a857 Resistor integration.
* New: In Isobar::PyResistor, manage type RPOLYH and RPOLY2PH.
* Change: In Hurricane::Resistor, rename plate nets from "PIN1" and
    "PIN2" into "t1" and "t2" (try to respect uniform naming scheme).
* New: In Karakaze/AnalogDesign.py, support for reading Resistor
    parameters.
* New: In Orosshi, ResistorSnake.py imported from Mariam Tlili's work
    and associated Resistor.py to make parameter conversion.
      Currently we only uses vertical layout for resistors.
      Added METAL2 horizontal terminals for resistors.
2020-03-30 12:40:29 +02:00
Jean-Paul Chaput 2fa8016eaa Make Pin terminals really punctuals (bug shown in nmigen/ALU16). 2020-03-20 18:55:38 +01:00
Jean-Paul Chaput 654ae5b8a4 Added compile script for Yosys in docker (for Debian 10). 2020-03-20 15:07:41 +01:00
Jean-Paul Chaput 2af531991e Correct drive of the Pin in AP driver.
* Bug: In CRL::ApDriver::DumpSegments(), when saving RoutingPads build
    on Pin *not* at the top level (that is, Pin from an instance),
    use the pin's orientation to choose the segment type.
      * NORTH/SOUTH becomes a Vertical.
      * EAST/WEST becomes an Horizontal.
      Formerly, the segment direction was guessed only for the bounding
    box, leading to segments in incorrect directions leading to DRC
    errors (in nmigen/ALU16, net "b(10)").
* Bug: In CRL/symbolic/cmos/technology.py, forgotten import for
    WarningMessage.
2020-03-20 12:05:12 +01:00
Jean-Paul Chaput 837de500aa Compliance with Debian 10 Buster.
* Change: In all tools, FindTOOL.cmake, no longer use LIB_SUFFIX to
    search for tool libraries but try "lib64/" then "lib/".
* Change: In bootstrap/socInstaller.py, take Debian 10 into account.
* Change: In bootstrap/docker, move from Debian 9 to Debian 10.
2020-03-19 18:18:35 +01:00
Jean-Paul Chaput b07a472250 Dynamic detection of Coriolis2 library directory.
* Change: In bootstrap/coriolisEnv.py, no longer rely on the uname to
    choose the library directory (lib64 or lib), but instead look for
    those locations (lib64 gets precedence).

Jean-Paul Chaput a12d88040a Capacitor support, at last.
* Change: In Hurricane::DbU::setGridPerLambdas(), allow the grid per
    lambda to be even. Needed when using nsxlib libraries that are
    drawn using a "half lambda" (two lambdas to get an Alliance lambda).
* New: In Oroshi/python, integrated capacitors. Modifications and
    correction from Mariam's code:
    * No need to redefine __setattr__() on CapacitorUnit.
    * Pitch horizontally & vertically (symbolic routing tracks) the
      devices.
    * Put the horizontal access tracks on the routing pitch.
    * Sets the horitontal metal2 wires as external components and
      NOT the capacitor plates themselves.
    * Makes the size (plates) of the unit capacitor a multiple of
      the foundry grid, not a floating number...
    * Correct the net ownership of horizontal tracks in
      drawHRoutingTracks().
    * Simplification & put error management directly inside of
      __isCapacitorUnitOK__().
* New: In Karakaze/python/AnalogDesign, capacitor spec now include
    the dummy parameter.

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.
