Repository to benchmark duck2's generated_rr branch of VPR.

A very simple benchmarking script run.sh is provided. Prior to running:

1. Build new branch of VPR:
   • Clone https://github.com/duck2/vtr-verilog-to-routing.
   • Checkout the generated_rr branch.
   • Build VPR.
2. Run the xc7/buttons test in your symbiflow-arch-defs repository.
   • The instructions for that are provided here.
3. Edit the script and set paths.
   • D2 is the path to the duck2/vtr-verilog-to-routing repository.
   • SYMB is the path to your symbiflow-arch-defs repository.
4. Good to go!

Here is the output I get from run.sh:
