VCD and VPD File Utilities
The include file must contain one scope or signal per line. Each
presented scope/signal must be found in the input VCD, EVCD,
or VPD file. If the file contains a scope, and separately, also
contains a signal in that scope, vcsplit includes all the signals in
that scope, and issues a warning.
Note:
If you use both -include and -scope options, vcsplit uses
all the signals and scopes indicated.
input_file
Specifies the VCD, EVCD, or VPD file to be used as input.
Note:
If the input file is either VCD or EVCD, and it is not specified,
vcsplit takes its input from stdin. The vcsplit utility has this stdin
option for VCD and EVCD files so that you can pipe the output
of gunzip to this tool. If you try to pipe a VPD file through stdin,
vcsplit exits with an error message.
-min min_time
Specifies the time to begin the scan.
-max max_time
Specifies the time to stop the scan.
-ignore ignore_file
Specifies the name of the file that contains a list of signals/scopes
whose value changes are to be ignored in the output file.
If you specify neither include_file nor
selected_scope_or_signal, then vcsplit includes all the
value changes in the output file except the signals/scopes in the
ignore_file.
