DDR4 Verification IP

Truechip's DDR4 Verification IP provides an effective & efficient way to verify the components interfacing with DDR4 interface of an ASIC/FPGA or SoC. Truechip's DDR4 VIP is fully compliant with Standard DDR4 Version JESD79-4B specification from JEDEC. This VIP is a light weight with an easy plug-and-play interface so that there is no hit on the design time and the simulation time.
