The Command file Syntax

instance/s.
• generate only the port information for the specified instance/s.

Before writing a command file, please note the following:
• All commands must start as a first word in the line, and the
arguments for these commands should be written in the same line.
Example:
dumpvars 1 adder4
• All comments must start with “//”.
Example:
//Add your comment here
dumpvars 1 adder4
