This is an open source collection of timing constraint files targeted towardsqualifying the timing capabilities of an FPGA CAD flow, such as VTR.Provided is also a set of scripts which can run these benchmarks on VPR, targetingZero ASIC's z1010 architecture; however, this can be used to target any VTR-compatiblearchitecture.

The scripts require some CAD tools in order to run and test the benchmarks. Wewill be using the SiliconCompiler project to manage the tools and versions.The following commands should install the correct versions of the tools that thisproject requires..
# Optional: Create a python virtual environment.python3 -m venv .venvsource .venv/bin/activate# Install this directory as a Python module.pip install .# Install siliconcompiler.pip install --upgrade siliconcompiler# Install necessary tools using SiliconCompiler (these should update your PATH).sc-install yosys-wildebeest opensta vpr
For the tests in this benchmark, we will run them on Zero ASIC's z1010 architecture.The choice of architecture was somewhat arbitrary; however, we do need an architecturethat has the necessary liberty files which can be used for post-implementationtiming analysis. This architecture is also built-into Wildebeest right now,so it is slightly more convenient.The following commands will download the latest release of the z1010 architectureand untar it into this directory.
wget https://github.com/siliconcompiler/logiklib/releases/download/v0.2.0/z1010_cad.tar.gztar -xvzf z1010_cad.tar.gz
# Run the benchmarks through the test suite.python3run_suite.py# The results are returned as a CSV file in a run directory.# Optional: These results can be visualized using the following script:pipinstall .[vis_scripts]python3scripts/visualize_results.py--inputruns/run001/results.csv--outputruns/run001/results.png
