Jean-Paul Chaput c80e99c0a1 Create clusters for wire only chunks and add diodes if they are too long.
Protecting clusters of sinks is not enough. There can be very long
wires that far exceed the protection capacity of one diode. Instead
of putting a bunch of diodes near the sinks, we choose to put them
regularly along the interconncting wires.
  With this approach we are down to 7 antenna violations on LibreSOC
LS180 test chip.
  This will get less good results on arlet6502 & ao6800 because of the
core being a long way from the I/O pads. Should create jumpers on thoses,
but it is for later.

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 It may be quite outdated from the *devel*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