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 documentation of the latest stable version is also available online. It may be quite outdated from the devel version.

Building Coriolis

Build has been successfully testet on Ubuntu 14.04.5 LTS with g++-4.8.4. Does not build on Ubuntu 16.04 LTS and not on Ubuntu 18.04 LTS. Please consult "buildhistory" file.

To build Coriolis, ensure the following prerequisites are met:

• Python 2.7.
• cmake.
• boost.
• bison & flex.
• Qt 4 or 5.
• libxml2.
• 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
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
