Jean-Paul Chaput 2a40fa7d92 New "obstacleDw" for Kite.
* New: In CRL Core, in RoutingLayerGauge, adds a new parameter "obstacleDw".
    It represents the distance to add from the *edge* of a blockage segment
    to the next *axis* of a routing track. This was previously computed as
    the pitch minus the mimimum half wire width. This works if the pitch
    is *equal* to the wire width plus the minimal distance (edge to edge).
    But if the wire width is less, than it leads to too great a distance
    around obstacles, making them bigger than they are. And potentially
    blocking everything. To summarize:
         before:  obstacleDw = pitch - wireWidth/2  (deduced)
         after:   obstacleDw = explicitly setup, usually:
                               pitch - max(wireWidth)/2
      Modify the Alliance configuration helper and the various kite.conf
    file accordingly.
* New: In Kite, in BuildPowerRails, make use of "obstacleDw" to compute
    the footprint of a blockage.

Jean-Paul Chaput db60fe0aa6 New coriolis launcher. Configuration files cleanup.
* Change: In CRL Core, simplify the loading sequence. The technology,
    both symbolic and real is now loaded directly from coriolisInit.py
    and not through the Alliance loader. This was a leftover from the
    time configuration was in XML. Remove others traces of XML loading.
      Remove SYMB_TECHNO_NAME, REAL_TECHNO_NAME & DISPLAY from the Alliance
    environement, as they was no longer used.
      Note that technology *still* need to be loader *after* Alliance
    framework has been initialized.
      Gauge information is moved from <alliance.conf> to <kite.conf>.
* Bug: In Coloquinte, in optimization_subproblems.cxx static variables
    must not be inlined. Generate a problem when linking in debug mode
    (seems the symbol gets optimised out).
* Bug: In Katabatic, in Grid::getGCell(), when the coordinate is *outside*
    the area, do not try to find a GCell, directly return NULL.
* New: In Unicorn, create a generic command launcher named "coriolis" which
    automatically take cares of all environement setup, then run a command
    by default, it's <cgt>, but it can be anything. For example: <zsh>.

Jean-Paul Chaput 4d184c7a75 Added etesian.conf in ispd05 symbolic technology. 2015-03-02 23:44:55 +01:00
Jean-Paul Chaput b18219d807 Integration of the latest Coloquinte in Etesian & misc modifs.
* New: In Bootstrap, in Builder & coriolisEnv.py support for RHEL7/SL7.
    The sub-directory name is 'el7_64'.
      In qt_setup() add QtSvg to list of Qt5 & Qt4 used libraries.
* New: In Hurricane, In Cell add a placeholder for flags. First use to
    store whether the Nets have been transhierarchically flatteneds.
* New: In Hurricane, In NetRoutingState add an Unconnected flag for
    more accurate diagnosis.
* New: Hurricane, in CellViewer add an entry menu for stress tests.
    The script must be named "stressScript.py" in the cwd.
* Change: In CRL Core, in display.conf add a scaling parameter for the
    display threhold of the layer. This way we can adapt to different
    standard cells height.
* Change: In CRL Core, in ISPD05 bookshelf loader, use the pitch of the
    cell gauge instead of a hard-wired 5.0.
* Change: In Cumulus, in ClockTreePlugin, add support for Etesian placer
    and a new configuration parameter to choose between Mauka/Etesian.
* New: In Etesian, support for the latest Coloquinte.
    Add feed insertion stage.
* Bug: In Kite, In BuildPowerRails, check that _ck is not NULL before
    tring to access it's name...
* Change: In Kite, check if the Cell has it's Nets flattened before
    doing it (or not).
