C-15
Simulation Options
+vcs+nostdout
Disables all text output from VCS including messages and text
from $monitor and $display and other system tasks. VCS still
writes this output to the log file if you include the -l option.
Options for Discovery Visual Environment and UCLI
-ucli
Starts the UCLI debugger command line
-l log_filename
Specifies a log file that contains the commands you entered and
the responses from VCS and DVE.
-i input_filename
Specifies a file containing UCLI commands. VCS executes these
at the start of simulation.
-k key_filename
Specifies a file where VCS records the UCLI commands it
executes. You can use this file as input with the -i option in a
subsequent simulation.
Options for VPD Files
+vpdbufsize+number_of_megabytes
To gain efficiency, VPD uses an internal buffer to store value
changes before saving them on disk. This option modifies the size
of that internal buffer. The minimum size allowed is what is
required to share two value changes per signal. The default size
is the size required to store 15 value changes for each signal but
not less than 2 megabytes.
