1.Compile your design using the -simprofile compile-time option.
Important:
If this is not the first compilation of your design, delete the csrc and simv.daidir directories and simv executable file before this step. Incremental compilation is not yet supported for the unified profiler.

2.At runtime, you can enter the -simprofile runtime option with a keyword argument or sub-option to specify the type of data VCS MX collects during the simulation. These keyword arguments or sub-options are as follows:
time

The time argument specifies collecting CPU time profile information.

mem
The mem argument specifies collecting machine memory profile information.

noprof
Tells VCS MX not to collect profiling information at runtime. Synopsys recommends entering this runtime option and keyword argument or sub-option instead of sim
