Adam Chlipala just pointed me out that the source code for our joint paper at CAV 2013 was not available anymore on the web. This is due to the fact that my old web-page at Inria was removed. So, I am delighted to take this as an opportunity to make the Fe-Si git repository available on github!
Fe-Si is a simplified version of Bluespec, an hardware description language based on a notion of guarded atomic actions. Fe-Si is defined as a dependently typed deep embedding in Coq. It comes with a compiler whose target corresponds to a synthesisable subset of Verilog or VHDL. A key aspect of our approach is that input programs for the compiler can be defined and proved correct inside Coq. Then, we use extraction and a Verilog backend (written in OCaml) to generate a certified version of an hardware design.
