Why Avery Verification IP for CXL?

Work more efficiently, develop more complex tests and work on more complex topologies, such as multi-path, multi-link solutions. Get maximum productivity and flexibility for the verification of block level, subsystem, and system-on-chip (SoC) designs.

Our comprehensive verification solution features an advanced Universal Verification Methodology (UVM) environment that incorporates constrained random traffic generation, robust packet, link, and physical layer controls and error injection, protocol checks and coverage, functional coverage, protocol analyzer-like features for debugging, and performance analysis metrics.

Avery compliance testsuites offer effective core through-chip-level tests, including those used in compliance workshops as well as extended tests developed by Avery to cover the specification features.

CXL 3.0

Avery's CXL virtual platform and VIP co-simulation helped reduce our validation time as we were able to perform extensive pre-silicon verification on our Leo Memory Connectivity Platform that supports CXL 2.0 and 1.1 technologies, and we are ready for real-world deployment. We look forward to utilizing a similar approach as we evolve next generation CXL designs.
