High speed memory design is challenging. With faster read/write speeds and difficulty accessing components, key to a good DDR4 PHY is careful design across the SoC, package, board, and system challenges. To do it right, it helps to look to Tektronix and partners like Nexus Technologies, SK Hynix, TSMC and Cadence for IP, Simulation and Validation Test.
