In reply to dave_59:

With $realtime I can see the difference

149.000ns: TB.GLD_C0: always execution
149.500ns: TB.GLD_C0: always execution
150.000ns: TB.GLD_C0: always execution
150.500ns: TB.GLD_C0: always execution
151.000ns: TB.GLD_C0: always execution
151.500ns: TB.GLD_C0: always execution
152.000ns: TB.GLD_C0: always execution
152.500ns: TB.GLD_C0: always execution
153.000ns: TB.GLD_C0: always execution
153.500ns: TB.GLD_C0: always execution
154.000ns: TB.GLD_C0: always execution
154.500ns: TB.GLD_C0: always execution
155.000ns: TB.GLD_C0: always execution

So $time rounds the value, while $realtime doesnt.
