Jean-Paul Chaput 02eb5c56ad Improvements in routing quality for ARMv2a 
* Change: In Katana::SegmentFsm::_slackenStrap(), make unbreakable segments
    pass through the LocalVsGlobal state so when other try to ripup them
    they are prioritary. Otherwise some could go through Unimplemented
    directly, without allowing other to attempt to make a detour.
* Change: In Katana::NegociateWindow::NegociateOverlapCost(), when a
    global, which is about to be slackened wants to use a track where there
    is a segment directly connected to a terminal with a significant
    ripup count, mark it as "AtRipupLimit" so it tries to avoid it.
      The idea is that globals with high ripup count must avoid terminal
    segments because it is likely they will be riped up again so they
    better find another track. This was leading to unsolvable configuration
    when two segments always want the same track. In this cas, the global
    would loose.
* Bug: In Katana::TrackSegment::canSlacken(), never slacken a segments in
    non-preferred direction.
* Change: In Anabatic::AutoHorizontal::_slacken(), allow slackening of
    segments which perpandiculars are in non-preferred direction, and
    not only directly attached to terminals.
* Change: In Anabatic::AutoSegment::canMoveUp(), re-allow segments which
    perpandiculars are in non-preferred direction to be moved up.
* Bug: In Katana::Manipulator::moveUp(), when moving up, do not forget
    to ripup and reschedule said segment.

===============
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/_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 It may be quite outdated from the *devel*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://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
