5.3.2 PDC Constraint File Commands for XCVR Signal Integrity
PDC constraint support uses the set_io pdc commands to set the related parameters.The settings are
applied only to the dedicated XCVR ports—TX_P, TX_N (outputs), RX_P, and RX_N (inputs)
Example: set_io -port_name TX_P -TX_EMPHASIS_AMPLITUDE 100mV_with_0dB
Note: User can set the parameter on the P or N side and it applies to both.
