Jean-Paul Chaput 0df4821806 Full update of the generated documentation for version 2.3 2019-05-27 18:49:51 +02:00
Jean-Paul Chaput e704306cad More robust deterministic netmap. Use classic string hash.
* Change: In Hurricane::Cell::NetMap, the hash function is now based on
    the string itself and not on the id of the SharedName. We now may
    remove the id attribute of the SharedName.
      This to ensure a more robust deterministic behavior. The sort
    order do not depend on whether we did use names before or not.

Jean-Paul Chaput 2f9a7076cb Forgoten hurricane analog generated documentation. 2018-11-29 12:03:26 +01:00
Jean-Paul Chaput fcd6d69a2f Analog integration part II. Analog place & route (slicing tree).
* Change: In Hurricane::CellWidget, set the minimal size to 350 pixels
    to fit my normal DPI secondary screen...
* Change: In Hurricane::Error(), reactivate the backtrace generation by
    default. Seriously slow down the program each time an Error is to
    be constructed.
* Bug: In Analog::Device::preCreate(), check for NULL Technology before
    attempting to use it.
* Change: In Hurricane/Analog, remove all '*Arguments*' classes and their
    Python interface. It was an obsoleted way of passing devices parameters
    to the Python layout generators (located in Oroshi). Now we just get
    them straight from the Device with the getParamter() method.
* Change: In CRL::System CTOR, add Python pathes for Oroshi & Karakaze.
* Change: In Oroshi/Python/WIP_*.py layout generator scripts, remove
    all uses of the "Arguments". Directly access the parameters through
    the device itself. Make the checkCoherency() with identical arguments
    as of layout().
* New: Bora tool that performs analog place & route. Based on a slicing
    tree representation. It is the thesis work of Eric Lao.
      Code beautyfication and some programming cleanup.
* New: Karakaze tool, provide the Python base class AnalogDesign used
    to build an analog design. Create/configure devices and assemble
    them in a slicing tree.
* Change: In Unicorn/cgt.py, display the stack trace in case of an
    ImportError exception as well as for other exceptions.
      Add Bora to the set for included tool engines.
2018-10-18 18:10:01 +02:00
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.

Jean-Paul Chaput c5034a9156 Typo in CMakeLists.txt : AND instead of "and". 2018-06-06 23:22:18 +02:00
Jean-Paul Chaput 767407736d Add a fully generated documentation in the git repository.
* Change: In all tools supplying documentation, as we use some specific
    software to create the doc, they may not be available, or worse, be
    and incompatible version. So, by default, we install the files shipped
    with the git repository. To force a full doc rebuild, use the "--doc"
    flag of ccb.py.
2018-06-06 18:42:26 +02:00
Jean-Paul Chaput 41c9959e30 Added support for diagonal wires (45° and 135°)
* New: In Hurricane::Diagonal, new object to represent 45° and 135°
    segments (X routing). Althought they have source & target, they
    are not articulated like Horizontal & Vertical, due to the
    combined displacement of X and Y (diagonal).
      Maybe we should create a common class for all the polygons
    to make "::getContour()" a method.
      Now we could represent self capacitances and high frequency
    wires.
2018-05-07 13:46:44 +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.

Jean-Paul Chaput a033e3ba98 More doc unification and cleanup. 2017-07-17 19:12:18 +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.

Jean-Paul Chaput 0efe75af00 Implementation of DataBase native save/restore in JSON (step 3).
* Test: post-receive hook on server should send mail [1].
* New: In VLSISAPD, in Parameter, callback have now a tag, which the
    pointer to the caller. This allow for the callback removal when
    the caller is destroyed.
* New: In VLSISAPD, in WidgetDescription, when associated to a parameter,
    the destructor must remove the associated callback function on
    the Parameter.
* New: In Hurricane, added JSON support for Configuration, separated
    from vlsisapd, as the support is not available at this point.
    JSON support for Configuration, Parameter & LayoutDescription.
* Change: In Hurricane, in JsonStack, the stack of JsonObjects has been
    displaced here from HurricaneHandler. This way, all
    JsonObject::toData() can access the JsonOjects in the context
    of the parser.
* New: In Hurricane, in DBo::toJson() added support for Entity by
    reference (ids).
* New: In Hurricane, added JSON support for all Layer sub-class types.
* New: In Hurricane, in Technology, export the Layers, but must be
   sorted by increasing mask value.
* New: In Hurricane, in Entity, added support for Entity by reference (ids).
* New: In Hurricane, in DataBase, added technology full support.
* New: In Hurricane, In JsonNet, move the ring rebuild management from
    JsonStack to JsonNet.
* New: In Hurricane, added JSON support for NetAlias, NetExternalcomponents
    (not cleanly implemented as a Relation).
* New: In Hurricane, new method Cell::fromJson() to load a cell from
    a JSON file.
* New: In Hurricane, In Graphics, make it an observable, for when JSON
    fully reload the graphic state, it must be able to notify other
    objects (namely the Controller).
* New: In Hurricane, in ControllerWidget, observe the Graphics to regenerate
    the palette as needed. New method ControllerTab::graphicsUpdated().
* New: In Hurricane, in RawDrawingStyle added a destructor to release the
    Qt pen/brush. Added JSON support for HSVr, DrawingStyle, DrawingGroup,
    & DisplayStyle.
* New: In Hurricane, in GraphicsWidget, rewrite correctly the readGraphics()
    to erase the previous widgets and re-create the new ones.
* New: In Hurricane, in PaletteWidget, correct re-creation of the layout/widgets
    in case of Graphics change.
* New: In CRL Core, in System, register the parameters callbacks with
    the address of the object, for later deletion.
* New: In CRL Core, in AllianceFramework, make it observable, to notify
    library changes. For the AllianceFramework creation, now allow to
    completly bypass the Python initialization system, when we expect
    to restore it from a full blob. Added methods to sets the default
    RoutingGauge & CellGauge.
* New: In CRL Core, added JSON suppport for CellGauge, RoutingLayerGauge
    & RoutingGauge.
* New: In CRL Core, in LibraryManager, oberver AllianceFramework, to update
    the list of libraries in case of change (for JSON full reload).

Jean-Paul Chaput 5baddeb558 Implementation of DataBase native save/restore in JSON (step 2).
* New: In boostrap, in ccb.py, added support for the "support" project
    which contains external dependencies. Currently contains only
    RapidJSON. Those dependencies must be cloned here manually.
* New: In Hurricane, Initializer class for an ordered static initialization
    across different compilation modules.
* Change: In Hurricane, at DataBase level, no longer save the Cells in
    the libraries, but create and ordered list of Cell. Deepest cells
    (leaf cells) first. To avoid dependency problems.
* New: In Hurricane, JSON support for Property.
* New; In CRL, added JSON support for AllianceFramework, Environement &
    Catalog and their associated properties. Adjustment of the
    AllianceLibrary creation policy.
2016-01-21 00:25:39 +01:00
Jean-Paul Chaput ae6eeb8f56 Merged QuadTrees in overlayed Cells (placed together).
* New: In Hurricane, in Cell & Instance, add the ability to merge the
    QuadTree when *second level* instances of a Cell are placed in
    the same space as the top Cell. This is the case of a deeply
    hierarchical design made of only standard cells that are to
    be placed in a "flat" manner.
      The design is uniquified then the intermediate instances models,
    which should be unique at that point have their QuadTree merged
    through a call to Instance::slaveAbutmentBox(). That method will
    make the model of the instance use the QuadTree of the Cell to
    which the instance belong. The instance model no longer posseses
    a dedicated QuadTree. As a corollary the abutment box of both
    Cell are kept identical and the Instance has it's transformation
    set to (0,0,ID).
      Remark: when we talk about "QuadTree", we mean in fact the
    QuadTree for the instances *and* the SliceMap (Layer+QuadTree).
      Consequence in Query: when going through the resulting
    "flattened" QuadTree we will find objects with an incomplete
    Path du to the fact that we didn't have to explore their
    Instance/Cell level to reach them. The shunted part of the
    Path is stored in the Go master Cell in the _shuntedPath
    attribute. This also affect the displayed depth of hierarchy,
    but not too badly.
* New: In Hurricane, in Cell, new methods:
    - Cell::updatePlacedFlag() : set the placement flags.
    - Cell::isUnique() : one or less instance.
    - Cell::isUniquified() : is the result of an uniquification.
    - Cell::isUniquifyMaster() : is the reference cell of the
    uniquification.
* Change: In Hurricane, in Cell::Uniquify(), uniquify a Cell only
    if it is unplaced. We do not need to duplicate placed Cells
    (see datapathes).

Jean-Paul Chaput 4bf5cf74b4 Policy CMP0022 for CMake. Forgotten library in Unicorn link. 2015-06-11 18:01:39 +02:00
Jean-Paul Chaput 770b1fbbbc Support for Uniquification. Rewrite of the Blif parser.
* New: In Hurricane, In NetAlias & Net, add an AliasList collection to
    iterate over all the aliases names (this *not* include the main
    net name).
* New: In Hurricane, In Cell, Instance & Net add support for cloning and
    uniquification (update documentation).
      All Cells that are uniquified from a given model are kept in an
    Uniquify relation. This relation allows to get all the clones and
    generate unique clone names by adding a "_uXX" suffix.
* Bug: In Hurricane, the Cell::_isFlattenLeaf attribute was not initialized
    in the constructor.
* Change: In CRL Core, in AllianceFramework::getCell(), no longer destroy
    a partially loaded Cell in case of parser failure, let the incomplete
    Cell be.
* New: In CRL Core, in ApParser, if all the instances are placed, sets the
    Cell::Placed flag.
* Change: In CRL Core, in BlifParser, complete rewrite of the parser.
    Not so good an idea afterwards...
* New: In Etesian, uniquify the design before placing.
* Change: In Kite, display the list of unrouted wired after all other
    statistics.

2014-05-13 17:11:48 +02:00
Jean-Paul Chaput dda3f99fd8 Update documentation for compliance with doxygen 1.8.5.
When upgrading from doxygen 1.5.x to 1.8.5 the way the documentation
is generated has underwent many changes, particularly in the headers.
* Change: In <header.html>, must include the javascripts <jquery.js>
    and <dynsections.js>.
* In <CMakeLists.txt>, as the header is customized, doxygen seems not
    copy some files like the javascripts and some images (open.png,
    closed.png). So we copy them from doxygen installation and make
    the CMakeLists.txt install them. I hope they will not change too
    much in the future.
* In <doxyfile>, disable markdown support as it do not interpret
    correctly the formating we already adopted (with a left margin
    to put command into). Use HTML_EXTRA_STYLESHEET instead of
    HTML_STYLESHEET. Enable the index (DISABLE_INDEX=NO), for the
    top header. Enable dot for inheritance diagram. Set the
    EXAMPLE_PATH=. to include the synthetic hierarchy.
    Correct the tag inclusion (faulty path in some places).
* In <SoC.css>, create style for the new header generated by doxygen.
* In the documentation, move the synthetic hierarchy into a module.

Jean-Paul Chaput 14a5f5f7ef Documentation restructuration
Documentation restructuration:
* Bug: in <hurricane>: bad figure for transf-R1.
* Change, in <kite>: Remove deprecated configuration variables.
* New: documentation <tool> to regroup all documentation not directly
  related to one tool.
* Change, in <crlcore>, move the user's guide and the top doc index
  into <documentation>.
* New, in <documenation>: added Python script demo based on AM2901.
2014-03-11 12:21:31 +01:00
Jean-Paul Chaput 34e0edfd61 Cleanup after SVN importation, <ccb> builder script adaptation.
Project hierarchy reorganisation:
* With svn, we were doing a tool by tool checkout, suppressing the
  whole repository hierarchy level.
* The tools were also grouped, inside one repository, into multiple
  projects (<bootstrap>, <vlsisapd>, <coriolis>).
* We do not want to split up each tool into a separate repository,
  given their tight integration (except for vlsisapd).
* We choose to simplify, and consider all tools in a svn repository
  one project. Due to the way Git clone repositories, the directory
  containing the project is now to be seen under "src/".

CMake modifications:
* Now that the <vlsisapd> and <bootstrap> projects are merged into
  coriolis, modificate the top CMakeLists.txt of each tool to uses
  only Coriolis (and bootstrap hard wired).

CCB compile script modifications:
* Uses the new source tree hierarchy, with the project directory
  inserted.
* Remove (comment) all parts relateds to svn managment.
* Git is sufficiently simple so that we do not want to integrate
  command shortcut into the script.

SVN cleanup:
* Remove the obsolete <chamsin> tool, that has become the full fledged
  <chams> project long time ago.
2014-02-26 18:24:41 +01:00
Jean-Paul Chaput 12f595941a * ./hurricane/src/hurricane:
- New: Added an id on DBo, SharedName and SharedPath to ensure
        database determinism. All the hash key now uses the id instead
        of the object's pointer (see _getHashValue()).
    - Change: In RoutingPad, position is now only relative to the anchor,
        no more (dx,dy). Add a isPlacedOccurrence() to check if all the
        occurrence in the path are fixed and thus the position meaningful.

  * ./hurricane/doc/hurricane:
    - Change: In Cell, added doc about PlacementStatus.
    - Change: In Transformation, more detailed explanations about the
        orientations. A little beautifying too...
    - Change: RoutingPad doc update.
    - Change: Entity doc update (for id).
    - Change: In HTML header/footer uses the new SoC.css.
2013-12-04 01:26:07 +00:00
Jean-Paul Chaput f8343fdfc4 * ./hurricane:
- New: In hurricane/doc, added documentation RoutingPad, HyperNet & Query.
    - New: In isobar, added support for RoutingPad.
    - Change: In PyComponent, getCenter() method moved to it's right place in
        the base class.
    - Change: In PyPath, added duplicated methods (ApplyOn <-> applyOn and
        Invert <-> invert).
2013-03-13 13:38:15 +00:00
Jean-Paul Chaput 47f3771f1d * All Tools:
- A complete sweep of cleanup to suppress allmost all compiler warnings.

  * ./hurricane/doc/hurricane:
    - New: Documentation cleanup and update, particularly on the new Layer
        derived classes.

  * ./hurricane/src/hurricane,
    ./hurricane/src/isobar,
    ./hurricane/src/viewer:
    - New: Creation of new methods, more explicit on DbU. Based on a to/from
        naming scheme.
    - New: Python support extented to include all objects needed to configure
        through python scripts.
    - Change: Finally understood what's causing the _XOPEN_SOURCE redefinition.
        Basically the Python.h must be included first before any other
        include. The type-puned problem will remains still (that is a Python
        problem, not our own).
    - Change: In DisplayStyle, uses shared_ptr for DrawingStyle instead of
        custom made reference count.
2012-11-16 12:48:38 +00:00
Jean-Paul Chaput 4db3b0b3de * All tools:
- Change: adopt a tree layout compliant with the UNIX FHS.
        * includes under      TOP/include/coriolis2.
        * shared datas under  TOP/shared/coriolis2.
        * docs under          TOP/share/doc/coriolis2.
        * configuration under TOP/etc/coriolis2

  * ./crlcore:
    - Change: In Environment, comply to the new tree layout, search configuration
        files under TOP/etc/coriolis2/.

  * ./knik:
    - Change: In flute, comply to the new tree layout, get the "POW*.dat" files
        from TOP/share/coriolis2/flute-2.4.
2010-05-18 12:53:00 +00:00
Jean-Paul Chaput f8d79dc53e * All tools:
- Change: In the CMakeLists.txt, in all the install commands remove all
        the leading "/" as they prevents the CMAKE_INSTALL_PREFIX to be took
        into account. It was nevertheless working because buildCoriolis.py was
        using DESTDIR which is prepended anyway.
  * ./goodies:
    - Change: In buildCoriolis.py, no longer uses the DESTDIR but instead
        CMAKE_INSTALL_PREFIX.

2008-11-26 10:13:31 +00:00
Jean-Paul Chaput 01ddcf4279 * ./hurricane/src/hviewer :
- New feature : first try at a more ergonomic interface. The "Controller",
        a simple Tabbed window for managing all settings.
          Reorganize the way things are selected (Nets, Area, single), aglomerated
        selection.
          Use a "logical" progression Netlist -> Selection -> Inspector.
    - In CellWiddget, new Selection managment mecanism to ensure persistent
        Selection across cell modifications.
          New signals/slots to manage Cell modification :
          a. - cellPreModificated() : must be launched *before* the Cell modification
               by the tool about to modify it.
          b. - cellPostModificated() : must be lauched *after* the Cell modification
          This mecanism may be amended to automatically fit with the UpdateSessions.  
    - Cleanup (part 1) : more consistent name for widgets, replace the 'H' prefix by
        a "Widget" suffix. Objects are modified by not filenames yet (due to svn not
        liking file renaming and modications at the same time).
    - Improved support for static building in CMakeList.txt.

Jean-Paul Chaput 59e8d945d6 * ./hurricane/doc/hurricane :
- Documentation of DbU, replacing documentation of Unit.

 * ./hurricane/src/hurricane/hurricane/DBo.h :
   - Property set is now a mutable member, allowing const DBo to changes
       their properties. Strange side effect on SlotAdapter in which we
       need to declare two separate templates, one for const type and
       another for non-const type.
   - _getTypeName() defined to prevents noisy error message when a
       derived class (from DBo) do not want to implement support for
       the inspector.

Jean-Paul Chaput 5a7ddb8188 * ./hurricane :
- Unit evolution to allow Symbolic (lamda) and Real (grid founder) mixing.
       All functions related to Unit translations are now grouped under
       the "DbU" class (another tribute to OpenAccess). "DbU" contains
       only static attributes (constants) and methods. Unit itself becomes
       a typedef inside this class, hence the file renaming from Unit.{h,cpp}
       to DbU.{h.cpp}. Have to replace all instances of "Unit" by "DbU::Unit".
   - Doc will be updated shortly.
