The MIPI I3C standardized sensor interface provides a number of significant advantages over existing digital sensor interfaces. One of the most advanced features is the ability to operate in I3C high data rate modes, HDR-DDR, HDR-TSP and HDR-TSL, which provides the best performance in both speed and power. Alex Passi of Cadence Design Systems presents I3C interface basics and focuses on various verification aspects of I3C HDR modes through an advanced verification methodology based on coverage driven verification and real-life scenarios.
