UVM 1.2 new warning - a resource with meta characters in the field name has been created

In reply to Eranr:

But you have written the code, I guess. The dot(‘.’) is an Expression for globbing/regexp.
To overcome this issue you have to escape this special character by preceding a .
This results in

block\.subblock

But I’m surprized you are putting a Register sub-block into the config_db.
