CPRI 7.0 Verification IP

CPRI 7.0 Verification IP

Truechip's CPRI verification IP provides an effective and efficient way to verify the components interfacing with CPRI interface of an IP and SOC. Truechip's CPRI VIP is fully compliant with CPRI alliance specification for CPRI version v6.1 with backward compatibility to previous versions. The VIP is light weight with easy plug-and-play interface so that there is no hit on the design cycle time.
