I am having problems using a simulation clock in my testbenches.

[CGood8]

The .sv files compile in ModelSim but they do not compile in quartus prime.I have uploaded the tesbench in question in a .txt file and the error codes in produces in a separate .txt file

You may want to write the clocking block as

default clocking cb @(posedge Clock);

in line 43. I hope it helps.
