Gen5 CEM RX Compliance Simulation Methodology

The PCIe Gen5 CEM RX compliance test presents significant challenges compared to traditional electrical margin tests for marginal systems due to the injection of additional jitter and noise during the RX compliance testing process. Currently, there exists a notable gap in standardized PCIeGen5 CEM RX compliance simulation methodologies available to system designers for evaluating platform design risks prior to PCB board fabrication or system builds. This deficiency often results in costly system board redesigns when RX compliance tests fail in validation stage. This study introduces a new PCIe Gen5 CEM RX compliance simulation methodology that addresses this critical issue. The proposed approach enables system designers to evaluate whether a platform design meets CEM RX compliance standards before PCB board tape-out (TO). By implementing this methodology, designers can conduct comprehensive risk assessments of their designs through RX compliance simulations. The advantage of the proposed RX compliance simulation methodology is its potential to yield substantial cost savings for product development and accelerate time-to-market for product launches. By shift-left identifying and mitigating compliance issues early in the design stage, this methodology offers a proactive approach to ensuring design validity and reducing redesign times.
