Jean-Paul Chaput 094cb8a132 Improved handling of short nets (fully included in one GCell).
The short net mode degrade the routing in some cases. This will be
fixed in a next batch of commits.

* New: In Hurricane::NetRoutingProperty, added "ShortNet" flag for Nets
    that are completly inside *one* GCell.
* Bug: In CRL::BlifParser::Model::staticInit(), when looking for the
    output of zero and one cell, also skip the blockage net (as well as
    automatic and supplies).
* New: In Anabatic::AutoSegment, added "ShortNet" flag to know if the
    segment is part of a short net (fully included in *one* GCell).
      Also add accessor/mutators for the _analogMode flag (was it ever
    used before?).
* New: In Anabatic::NetBuilder::singleGCell(), if a RoutingPad is
    vertically small, add a vertical segment to give it some slack.
* New: In Anabatic::Dijkstra::_materialize(), detect "short net" as
    they have only one GCell in their source list...
* Bug: In AnabaticEngine::_loadGrbyNet(), reset the AutoSegment
    "short net" and "analog mode" creation flags between two different
    nets.
* New: In Katana::Configuration, added dedicated ripup for short net
    segmnts.
* New: In Katana: partially implemented support for "short dogleg", that
    is dogleg that are always kept in same metal because they connect
    neighboring perpandicular tracks. Not finished neither activated
    yet.
* New: In Katana::TreckElement and derived, export the the *short net*
    support from AutoSegment.
* Bug: In Katana::RoutingEvent::_processRepair(), when a segment is
    successfully inserted, re-process any perpandicular that is in
    repair state, as it may have a new chance to be placed.
* New: In Katana::SegmentFsm::slackenTopology(), always reject short nets.
* Bug: In Katana::Track::check(), correctly handle wide segments instead
    of issuing false check messages.

===============
Coriolis README
===============


Coriolis is a free database, placement tool and routing tool for VLSI designs.


Purpose
=======

Coriolis provides several tools to perform the layout of VLSI circuits.  Its
main components are the Hurricane database, the Etesian placer and the Kite
router, but other tools can use the Hurricane database and the parsers
provided.

The user interface <cgt> is the prefered way to use Coriolis, but all
Coriolis tools are Python modules and thus scriptables.


Documentation
=============

The complete documentation is available here, both in pdf & html:

   ./documentation/_build/html/index.html
   ./documentation/UsersGuide/UsersGuide.pdf

The documentation of the latest *stable* version is also
available online. It may be quite outdated from the *devel*
version.

    https://soc-extras.lip6.fr/en/coriolis/coriolis2-users-guide/


Building Coriolis
=================

To build Coriolis, ensure the following prerequisites are met:

* Python 2.7.
* cmake.
* boost.
* bison & flex.
* Qt 4 or 5.
* libxml2.
* RapidJSON
* A C++11 compliant compiler.

The build system relies on a fixed directory tree from the root
of the user currently building it. Thus first step is to get a clone of
the repository in the right place. Proceed as follow: ::

   ego@home:~$ mkdir -p ~/coriolis-2.x/src/support
   ego@home:~$ cd ~/coriolis-2.x/src/support
   ego@home:~$ git clone http://github.com/miloyip/rapidjson
   ego@home:~$ git checkout ec322005072076ef53984462fb4a1075c27c7dfd
   ego@home:~$ cd ~/coriolis-2.x/src
   ego@home:src$ git clone https://www-soc.lip6.fr/git/coriolis.git
   ego@home:src$ cd coriolis

If you want to use the *devel* branch: ::

    ego@home:coriolis$ git checkout devel

Then, build the tool: ::

    ego@home:coriolis$ make install

Coriolis gets installed at the root of the following tree: ::

    ~/coriolis-2.x/<OS>.<DISTRIB>/Release.Shared/install/

Where ``<OS>`` is the name of your operating system and ``<DISTRIB>`` your
distribution.


Using Coriolis
==============

The Coriolis main interface can be launched with the command: ::

    ego@home:~: ~/coriolis-2.x/<OS>.<DISTRIB>/Release.Shared/install/bin/coriolis

The ``coriolis`` script is tasked to guess it's location and setup appropriatly
the UNIX environment, then lauch ``cgt`` (or *any* command, with the
``--run=<COMMAND>`` option).

Conversely, you can setup the current shell environement for Coriolis by 
using the helper ``coriolisEnv.py``, then run any Coriolis tool: ::

    ego@home:~$ eval `~/coriolis-2.x/src/coriolis/bootstrap/coriolisEnv.py`
    ego@home:~$ cgt -V
