CPRI/eCPRI Verification IP

Truechip's CPRI/eCPRI Verification IP provides an effective & efficient way to verify the components interfacing with CPRI/eCPRI interface of an IP or SoC. Truechip's CPRI/eCPRI VIP is fully compliant with CPRI V7.1 and eCPRI V2.0 specifications with backward compatibility with previous versions. This VIP is lightweight with an easy plug-and-play interface so that there is no hit on the design cycle time.
