You are not at all clear what you are trying to do. Good you have the
Dragon book, so I assume that you want to write a syntax / semantics
checker for Verilog (I use it for CPLD and FPGA design).


Why not just let the VHDL compiler to issue an error, most do. So it
is not clear what you want to do.
