Jean-Paul Chaput 181b2e1080 Re-enable and check the building of I/O ring with pad spacers. 
* New: In cumulus/block.bigvia, add a getBoundingBox() method.

* New: In cumulus/block.configuration.GaugeConf.rpAccess(),
    add a vertical strap segment in case the RP is not high enough to
    accomodate the potential offset of the contact.
      In case of gauge with only two routing layers, if the RP
    is vertically accessed, do not put a VIA12 but just a METAL2
    contact (there will be *no* turn).

* Change: In cumulus/chip.CoreWire.drawWire(), the wire at *chip level*
    going to the pad was shrunk of 3 pitch when *not* in the preferred
    routing direction. Removing it as it creates gaps in some cases.
      This was likely needed for a specific kind of I/O pad so should
    be re-enabled on targeted cases in the future.

* Change: In cumulus/chip.corona.VerticalRail, manage in a smarter way
    the conflicts when a rail is accessed from both sides overlapping
    on an Y position. That is, from the supply I/O pads *and* from the
    *core* supply lines.
      Formerly, we just didn't connect the core power line, which was
    a mistake potentially leaving power rails unconnected (it it did
    occur on both sides).
      Also checks if the conflict really arise, that is, the power lines
    are both on top or bottom.

* Change: In cumulus/chip.pads.Side._placePad(), manage I/O pads with
    a bottom left corner of abutment box *not* at (0,0). Argh!

* Bug: In cumulus/chip.pads, create the filler pad instances in the
    chip, not in the corona.

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 It may be quite outdated from the *devel*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