VPD and EVCD File Generation
event_name
A unique string which describes the event. This event name
appears in the status bar of the Wave Window, Logic Browser, or
Register Window when the mouse is placed on the event marker.
severity
A single character with legal values E, W, or I, which indicates the
severity of the event. The severity of the event may be Error,
Warning, or Information respectively. Colors associated with the
severity level are set in the X Resource file. The defaults are
Red=Error, Yellow=Warning, and Green=Information. If the
severity is not interpretable, it defaults to E.
shape
A single character with legal values S, T, or D which indicates the
geometry of the event as drawn by VirSim, and are Square,
Triangle, and Diamond respectively. If the geometry is not
interpretable, it will default to T.
Runtime Options
You can use specific command line options to generate VPD files.
These options allow you to set the RAM buffer size, provide the VPD
default file name, specify the VPD file size, ignore file calls, check
licenses, and control what information is stored.
+vpdbufsize to Control RAM Buffer Size
To gain efficiency, VPD uses an internal buffer to store value changes
before saving them on disk. The +vpdbufsize command modifies
the size of the internal buffer.
