In reply to susharma:
There is no uvm_register_pkg. All of the UVM register functionality is contained within the uvm_pkg. That is why importing is is failing.
Is this an example from the Verification Academy. If it is, then we will need to look at updating it to the latest register implementation. There might be a few examples that use the old style that haven’t been updated.
Read the UVM Cookbook chapter on UVM Registers for the current implementation.
