As shown in the following figure, in this mode of operation only the CMAC receiver is enabled and the packet monitor will be enabled to verify the received data. For simulation, a partner test bench is instantiated to perform the functionality of the CMAC transmitter. This partner test bench will have a CMAC transmitter and a packet generator to generate the test data.
The following figure shows the Simplex RX mode for simulation.
