VPD and EVCD File Generation
Syntax:
+vpdbufsize+nn
Here nn is buffer size in megabytes. The minimum size is the size
required to store two value changes per signal and the default size
is the size required to store 15 value changes for each signal (but not
less than 2 megabytes).
Note:
VCS automatically increases the buffer size as needed to comply
with this limit.
+vpdfile to Set the Output File Name
The +vpdfile command allows you to specify the output file name.
Syntax:
+vpdfile+filename
Here filename is the VPD filename (default is vcdplus.vpd). You
must include the full file name with the .vpd extension.
+vpdfilesize to Control Maximum File Size
The +vpdfilesize command creates a VPD file, which never
exceeds a specified file size nn megabytes. When the file size limit
is reached, VPD continues saving simulation history by overwriting
older history.
