* Revision 1.3 1999/02/21 17:01:57 steve
* Add support for module parameters.
* Revision 1.2 1999/01/25 05:45:56 steve
* Add the LineInfo class to carry the source file
* location of things. PGate, Statement and PProcess.
* elaborate handles module parameter mismatches,
* missing or incorrect lvalues for procedural
* assignment, and errors are propogated to the
* top of the elaboration call tree.
* Attach line numbers to processes, gates and
* assignment statements.
* Revision 1.1 1998/11/03 23:28:52 steve
* Introduce verilog to CVS.
