Starting VirSim
+vcdfile+<filename>
The +vcdfile+<filename> command automatically translates the
VCS file to vpd format, then loads it immediately on startup. If Verilog
source files are supplied on the command line, it is assumed that
these source files match the VCD file. You can load multiple files by
repeating the
+vcdfile+<filename> command for each file.
+vpdfile+<filename>+start+<time>+end+<time>
The +vpdfile+<filename> command automatically loads a VCD+
history file on startup. If Verilog source files are supplied on the
command line, it is assumed that these source files match the VCD+
file. You can load multiple files by repeating the
+vpdfile+<filename> command for each file.
The optional +start+<time>+end+<time> command loads a time
range from a file. You do not need to specify both times. You can
specify just the start load time (to load everything from a certain point
on), just an end time (to load everything up to a certain point), both
the start and end times (to load everything in a range) or neither (to
load all available data from the file).
+sim+<simulator-path>
The +sim+<simulator-path> command immediately starts an
interactive session using the given simulator. If Verilog sources are
supplied on the command line, it is assumed that these source files
match the interactive simulation to be started.
Note:
If the default simulator type is not correct, you must also use
the+simtype command to select the simulator type.
