Are there any grammars for the open source Verilog system? I am looking for System Verilog, not simple Verilog grammars.
Verilog-Perl is open source and claims to have SystemVerilog support. You can contact the author of Perl CPAN to find out if it covers the full grammar (his email address is on the CPAN page).
