Why don't I see an difference in simulation results when I change the Tx drive strength settings of the IBIS-AMI transceiver models? - Why don't I see an difference in simulation results when I change the Tx drive strength settings of the IBIS-AMI transceiver models? Description You will not see any difference in drive strength of Altera® Tx IBIS-AMI models if only the Ivod IBIS-AMI parameter is changed. You also need to change the appropriate selected analog IBIS-AMI model. The following document details how to change the Tx drive strength.
