steve 739365abe5 Parse disable statements to pform. 2000-07-26 05:08:07 +00:00
steve 8fc2dc2cd1 Better parsing of expressions lists will empty expressoins. 2000-05-23 16:03:13 +00:00
steve 3676d66408 Module ports are really special PEIdent
expressions, because a name can be used
 many places in the port list.

steve 44838f8973 Add support for force assignment. 2000-04-22 04:20:19 +00:00
steve 4493e968da 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.

steve b1fd927acb 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.

steve 2dd010dc04 Named events as far as the pform. 2000-04-01 19:31:57 +00:00
steve 6eef54595f Support localparam. 2000-03-12 17:09:40 +00:00
steve e7efc2709a 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.
