Jean-Paul Chaput 2002282483 Add a zero-length segment compaction stage in Anabatic DTOR. 
* New: In AnabaticEngine::_gutAnabatic(), perform progessive compaction
    of segment of null length.
      CAUTION: Reduced segments *may* not be null length segments.
               They are "less or equal" than one perpandicular pitch and
	       can have their layer put into the perpandicular one.
                 They non-null one *must* be excluded for the compaction.
      Null segments are compacted starting from the one connecteds to
   non-null length segments. This is to avoid the compaction starting
   in the middle of a whole set of zero-segments that will block further
   compaction.
     This behavior was causing "zero-length" segment on orphaned layers
   that were causing minumal area DRC errors.
* Change: AutoSegment::canReduce() is modified so it now takes a flag
    argument to tell it to look for collapisble zero-length segments.
* New: AutoSegment::getNonReduceds(): returns the number of non-zero
    length segments connecteds to the current one.
* Change: In AutoSegment::reduceDoglegLayer(), use the perpandicular
    width of the routing layer instead of the regular (parallel) one.
      This was causing DRC errors.

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

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


Purpose
=======

Coriolis provides several tools to perform the layout of VLSI circuits.  Its
main components are the Hurricane database, the Etesian placer and the Katana
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 scriptable.


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

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

   ./documentation/output/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 It may be quite outdated from the *devel*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://www-soc.lip6.fr/sesi-docs/coriolis2-docs/coriolis2/en/latex/users-guide/UsersGuide.pdf


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 detects its location and setups the UNIX
environment appropriately, then lauches ``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
