WebDec 23, 2024 · In reply to Shubhabrata: A VCD file is very limited in what it can log. It is typically limited to signals only within modules, tasks and functions. The logging of interfaces isn't defined, so you won't see anything within your design. A tool's native logging is likely to have more information, so you should use that instead of VCDs.
