CoaXPress (CXP) Verification IP

Overview

CXP Verification IP implements digital interface for high speed image data transmission and intended mainly for Machine Vision applications. The interface is also suitable for other imaging applications and for high speed data transmission in other fields. CXP Verification IP provides an smart way to verify the CXP standard video data transmission and control interfaces between Host and Device. The SmartDV's CXP Verification IP is fully compliant with CXP specification and provides the following features.

CoaXPress (CXP) Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

CoaXPress (CXP) Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
