The Versal device GTM transceiver is designed and validated to meet protocols that assume the passive channel and link partner are compliant in all cases. The designed channel must be evaluated with a channel compliance tool or tolerancing test method stipulated in corresponding standards like channel operation margin (COM) for IEEE and OIF CEI to verify the conformance. In addition to channel compliance checks, channel simulation using an IBIS algorithmic modeling interface (IBIS-AMI) model should be run to confirm the final system margin.
