VCD and VPD File Utilities
If you specify an include_file and/or a
selected_scope_or_signal, vcsplit includes all value
changes of those signals/scopes that are present in the
include_file and the selected_scope_or_signal but
absent in ignore_file in the output file. If the ignore_file
contains a scope, vcsplit ignores all the signals and the scopes
in this scope.
-level n
Reports only n levels hierarchy from top or scope. If you specify
neither include_file nor selected_scope_or_signal,
vcsplit computes n from the top level of the design. Otherwise, it
computes n from the highest scope included.
-v
Displays the current version message.
-h
Displays a help message explaining usage of the vcsplit utility.
Note:
In general, any command line error (such as illegal arguments)
that VCS detects causes vcsplit to issue an error message and
exit with an error status. Specifically:
- If there are any errors in the -scope argument or in the include
file (such as a listing a signal or scope name that does not exist
in the input file), VCS issues an error message, and vcsplit exits
with an error status.
- If VCS detects an error while parsing the input file, it reports an
error, and vcsplit exits with an error status.
- If you do not provide either a -scope, -include or -ignore
option, VCS issues an error message, and vcsplit exits with an
error status.
