Migration from UVM1.1 to UVM1.2: Problems with Register Viewer + Warnings

Hi Sagar.

This might be related to which UVM library version you use, can you let us know if it's still a problem when you switch to the CDNS-1.2 (per your other topic on this forum).

Additionally, can you explain how you generated your UVM_REG class definitions? Did you use a builder tool like reg_verifier, or something else?

Regards,

Steve

Hi Steve,

this is a new problem I am facing (that I am not able to see the registers in the register viewer) after successful migration to CDNS1.2.

When I was using 1.1, there was no problem with the UVM register viewer (but with the hdl path definition), but after migration, I could open the register viewer, but with no register content inside. The only changes made was to migrate from UVM1.1d to 1.2.

Regards, 

Sagar.
