- *  Synthesis of comparator in expressions.
- *
- *  Connect the NetEvent and related classes
- *  together better.
- *
- * Revision 1.122  2000/04/15 19:51:30  steve

- *
- * Revision 1.121  2000/04/12 20:02:53  steve
- *  Finally remove the NetNEvent and NetPEvent classes,
- *  Get synthesis working with the NetEvWait class,
- *  and get started supporting multiple events in a
- *  wait in vvm.
- *
- * Revision 1.120  2000/04/12 04:23:58  steve
- *  Named events really should be expressed with PEIdent
- *  objects in the pform,
- *
- *  Handle named events within the mix of net events
- *  and edges. As a unified lot they get caught together.
- *  wait statements are broken into more complex statements
- *  that include a conditional.
- *
- *  Do not generate NetPEvent or NetNEvent objects in
- *  elaboration. NetEvent, NetEvWait and NetEvProbe
- *  take over those functions in the netlist.
- *
- * Revision 1.119  2000/04/10 05:26:06  steve
- *  All events now use the NetEvent class.

- * Revision 1.111  2000/03/08 04:36:54  steve
- *  Redesign the implementation of scopes and parameters.
- *  I now generate the scopes and notice the parameters
- *  in a separate pass over the pform. Once the scopes
- *  are generated, I can process overrides and evalutate
- *  paremeters before elaboration begins.
- *
- * Revision 1.110  2000/02/23 02:56:55  steve
