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.

===============
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 It may be quite outdated from the *devel*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
