Jean-Paul Chaput 3e825cc228 Katana routing algorithm adjustements for analog routing. 
* Bug: In Hurricane::Interval, the ::getSize() method was returning a negative
    length when the Interval was empty. Now return zero. This was causing
    slight cost functions side effect when computing the overlap of a segment
    with another one belonging to the same net (i.e. shareDelta)
* Bug: In Katana::AutoSegment::computeOptimal(), checks that the optimal
    position for the axis is indeed inside the GCell interval.
* Bug: In Katana::DataSymmetric::getSymmetrical(Interval&), reverse the shrink
    applied to GCells sides. Interval are of the type [min:max[ so after
    symmetric transformation they become ]smax:smin]. Apply a correction so
    that they are [smax:smin[ and could be merged with the paired interval
    (the one without symmetry applied).
* Bug: In katana::TrackCost::consolidate(), the overlap (now) always positive,
    and must be *substracted* to the "delta" (not *added*).
* Bug: In Katana::_computeNetOptimals(), now skip the already processeds
    AutoSegments instead of re-processing them.
* New: In Katana::AutoSegment::computeOptimal(), improved computation of
    the axis hint:
      - For analog net, propagate through the simple doglegs to find
        attractors.
      - Restrict the allowed interval to the union of GCell sides and
        segments constraints that are terminals.
      - Consider a local as "long" if it's length exceed 20 the P-pitch.
        (maybe make that a tool parameter).

===============
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/UsersGuide/UsersGuide.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 It may be quite outdated from the *devel*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
