You should be able to duplicate the agents connected to your reference model and DUT. Then connect the monitors analysis ports to the expected and actual analysis exports respectively.
If you have separate input and output agents, you might not have to duplicate the input agents, and just tie the inputs together.
If your two models are not 100% cycle, accurate with respect to each other then you’ll have to duplicate the sequences sent to each agent.
