This is graywolf - a fork of TimberWolf 6.3.5

TimberWolf was developed at Yale University, and was distributed as open source for a time until it was taken commercial. The last open-source version of TimberWolf does not perform detail routing, but is a professional-grade placement tool. In order to continue improving the open-source version, graywolf has been forked off from version 6.3.5 of TimberWolf.

The main improvement in graywolf is that the build process is more streamlined and that it behaves as a normal linux tool - you can call it from anywhere and no environment variables must be set first.

graywolf is used for placement in VLSI design. It's mainly used together with qflow. (http://opencircuitdesign.com/qflow/)

mkdir build
cd build
cmake ..
make  
sudo make install  

After "make", you can run the test suite: (unfortunately, the test will not work on 32-bit architectures yet)

make test

To dump out log for failing tests:

CTEST_OUTPUT_ON_FAILURE=1 make test

To run completely verbose tests:

make test ARGS="-V"

There are two main branches: master and dev. Since people expect master to be stable in a "production environment", any ground-breaking changes/refactoring must be merged into dev. Please do not open pull-request towards master for these changes.

Pull requests targeting specific bugfixes need to be merged into both master and dev, so it is ok to open a pull request for either of them.
