CPRI Verification IP

Truechip's CPRI Verification IP provides an effective & efficient way to verify the components interfacing with CPRI interface of an IP or SoC. Truechip's CPRI VIP is fully compliant with CPRI V7.1 specification with backward compatibility to previous versions. This VIP is lightweight with an easy plug -and- play interface so that there is no hit on the design cycle time.
