Signal spec and routing
WebFeb 1, 2024 · When performing system-level simulations, signal integrity at all DRAM locations needs to be checked. For DDR4 designs, the primary signal integrity challenges were on the dual-data-rate DQ bus, with less attention paid to the lower-speed command address (CA) bus. For DDR5 designs, even the CA bus will require special attention for …
