USB4 MAC Verification: Overcoming Serial Interface and Simulation Time Challenges
DescriptionUSB4 Router at MAC verification encounters challenges such as managing complex protocol interactions, signal integrity at high data rates (up to 80 Gbps), error handling, effective link training and creating accurate environments for comprehensive testing. Traditionally USB4 MAC DUT Verification is happening using PHY interface designed for USB4, or PIPE based PHY (Handling multiple protocol). To create reliable and high quality USB4 PHY requires intensive verification across different technologies and because of this PHY readiness is in the critical path of the overall USB4 verification. Also, Due to the serial interface of PHY, simulation time is very high, and it leads to performance issue hence separating PHY verification and MAC verification can help. To address these issues, we have introduced a solution where USB4 Version 1 and Version 2.0 MAC DUT can be verified without using serial interface.
