Jean-Paul Chaput f4204c52d7 Support for dedicated power plane in Cumulus (vertical stripes).
* New: In cumulus/plugins.chip.powerplane, build the overall power
    grid when there is a dedicated supply layer. Makes vertical
    supply stripes and connect them the *horizontal* power rails
    inside the blocks (could be in *any* layer).
      Stripes positions are determined by the pins createds by
    the pads module.
* New: In cumulus/plugins.chip.chip, use the powerplane builder
    if the RoutingGauge provides a PowerSupply kind.
* New: In cumulus/plugins.block.configuration, add support for
    PowerSupply gauges.
* New: In cumulus/plugins.block.pads, if the gauge provides a
    PowerSupply, create north/south border pins for power & ground
    to direct the corona to make vertical power strips.
      This assume that we are using LibreSOC like I/O pads that
    can be connected straight from everywhere in the corona.
      First and last 2 stripes are "cap end" and narrower.
      Positions and width of the sripes are set through the
    configuration parameters:
    * "chip.supplyRailWidth"
    * "chip.supplyRailPitch"
* Change: In cumulus/plugins.block.spares, now take into account
    the "placeArea" parameter.
* Change: In cumulus/plugins.block.bigvia, now have a per metal layer
    area that *may* be expanded if it is too narrow to put at least
    one cut. Add flags to allow controlled expansion of the metal
    plates.
      As a security, now raise an exception if no cut can be created.

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 It may be quite outdated from the *devel*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