I'm trying to run the testbench for a new module I created (UHD4) and I'm
getting the following error:

This file seems to compile without issue on my previous testbench, so I'm
not sure what the difference would be here. If anyone has any insights into
what could be going on I'd greatly appreciate it.

 

Thank you,
