VCD and VPD File Utilities
• All comments written after a command, must be preceded by a
space.
Example:
dumpvars 1 adder4 //can write your comment here
A command file can contain the following commands:
dumpports instance [instance1 instance2 ....]
Specify an instance for which an EVCD file has to be generated.
You can generate an EVCD file for more than one instance by
specifying the instance names separated by a space. You can
also specify multiple dumpports command in the same
command file
dumpvars [level] [instance instance1 instance2 ....]
Specify an instance for which a VCD file has to be generated.
[level] is a numeric value indicating the number of levels to
traverse down the specified instance. If not specified, or if the
value specified is "0", then all the instances under the specified
instance will be dumped.
You can generate a VCD file for more than one instance by
specifying the instance names separated by a space. You can
also specify multiple dumpvars command in the same command
file.
If this command is not specified or the command has no
arguments, then a VCD file will be generated for the whole design.
