The chiplet ecosystem and standards are still in their infancy. Consequently, official interoperability and compliance programs from workgroups like the UCIe Working Group are not yet available. Typically, it takes a couple of years after a specification is published for workgroups to organize interoperability or compliance events, as silicon is not available before then. This poses a risk for early adopters of the standards but also offers opportunities for companies to collaborate early in their design processes.
We will describe a simulation-based interoperability program that integrates UCIe IP from two companies into a simulation environment, focusing on LogPhy and D2D interoperability in two stages. Verification IP for UCIe is used to create interoperability test cases and drive traffic through RDI and FDI interfaces. We discuss the challenges encountered during the interoperability exercise, the test cases developed to demonstrate interoperability, and the results. Additionally, we explore how other companies can participate in similar interoperability efforts to accelerate the adoption and rollout of UCIe-based designs.
