No, you cannot simulate the CMU or CDR frequency tracking function with Altera® transceiver simulation models?
Due to a limitation of the Altera transceiver CMU and CDR simulation models, you must apply a reference clock and data rate that is equal to those you specified in your transceiver Megawizard™ file. The CMU and CDR may fail to lock if an incorrect reference clock or data rate is applied to the transceiver simulation model.
The CMU and CDR will correctly frequency track in hardware.
