Great simple tool. Almost perfect in every way.

We had been building different incarnations of this ourselves for years, but this one is even better and more complete.

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!
