Great simple tool. Almost perfect in every way.

Great tool. Web-based registers definition plus easy generation of multiple output formats. All done in a clear way.

If you have not tried airhdl , it is worth a go... It is a code generator for CSR blocks with very nicely written output in all major RTL's plus great documentation. Try it out!
