ParseError for User Defined Primitives

[TheMatt2]

It seems that Verilog user defined primitives are not supported by this parser.

If I put in an example with a user defined primitive, I get an error message.

primitive udp_and (c, a, b);
    output c;
    input a, b;

// in0 in1 sel :  out
    table
//      a b  c
        0 ?: 0;
        ? 0: 0;
        1 1: 1;
   endtable
endprimitive

Using the example parser, I get the following error message:

$ python3 example_parser.py udp_and.v

Sorry, the current version of Pyverilog does not support primitive. I think the modification of AST parser is not so difficult if add this feature based on the current parsing function for module.
