MIPI CSI-2 Verification IP Provides the mobile industry a standard, robust, scalable, low-power, high-speed, cost-effective interface that supports a widerange of imaging solutions for mobile devices. MIPI CSI-2 Verification IP provides an smart way to verify the MIPI CSI-2 standard data transmission and control interfaces between transmitter and receiver. The SmartDV's MIPI CSI-2 Verification IP is fully compliant with version 4.0 MIPI Alliance specification for serial Interface and provides the following features.
MIPI CSI-2 Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
MIPI CSI-2 Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
