Jean-Paul Chaput 76d468f6d5 Change in feed & tie managements to fill the empty row spaces. 
* Change: In EtesianEngine::_postCreate(), issue a warning if the list of
    feeds is empy (configuration: "cfg.etesian.feedNames").
* New: Add a FeedCeels::getFeedByWidth() method to get feeds by their
    width in DbU::Unit and not only pitches.
* Change: In Placement::Slice::fillHole(), invert the tie filling and
    feeds filling stage. Now we first try to fill the row hole with
    feeds, using the widest first, and if they are not configured or
    too wide, use the tie.
      As the tie *should* also be integrated in the feed list, we may
    suppress altogether the fallback tie filling step. Keep it for now.
* Change: In Placement::slice::createDiodeUnder(), the inserted diode
    *may* be smaller than the feed it replace. So, in this case, add
    a complementary feed to fill the gap.
    NOTE 1: Out of lazyness, we add only *one* complementary filler
            cell. So there *must* be one of a width wich correspond
	    exactly to the difference between the original feed and
	    the diode. Otherwise, gap will remains.
    NOTE 2: With wider feed cells, they may cross the GCell border.
            But we must insert the diode under the GCell, otherwise
	    the global routing will be defective. So, for now, reject
	    feeds that cross the boundary. Must be done more smartly
	    by inserting the diode over the left or right side of
	    the feed.

===============
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 It may be quite outdated from the *devel*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 3.
* 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://gitlab.lip6.fr/vlsi-eda/coriolis.git
   ego@home:src$ cd coriolis

Then, build the tool: ::

    ego@home:coriolis$ make install

If you encounter issues, please consult SUPPORT.rst for tips.
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
