VCD and VPD File Utilities
Limitations
The verbose option -v may not display error or warning messages
in the following scenarios:
• If the reference signal completely or coincidentally overlaps the
compared signal.
• During hierarchy merging, if the design object already exists in
the merged file.
During hierarchy merging, the -heir option may not display error
or warning messages in the following scenarios.
• If the start and end times of the two dump files are the same.
• If the datatype of the hierarchical signal in the dump files do not
match
Value Conflicts
If the vpdmerge utility encounters conflicting values for the same
signal, with the same hierarchical name, in different input VPD files,
if does the following when writing the merged VPD file:
• If the signals have the same end time, vpdmerge uses the values
from the first input VPD file that you entered on the command line.
• If the signals have different end times, vpdmerge uses the values
for the signal with the greatest end time.
In cases where there are value conflicts, the -v option displays
messages about these conflicts.
