Verification IP for MIPI DSI 

 

Overview
Synopsys Discovery™ Verification IP (VIP) for MIPI Display Serial Interface (DSI) helps the verification of DSI Host (typically the application or baseband processor side) or DSI Device (typically the peripheral side). MIPI-DSI VIP supports both High Speed (HS) transmission and Escape Mode. In Escape Mode it supports Ultra Low Power State (ULPS), Low Power Data Transmission (LPDT), Trigger messages and Bus Turnaround. It simplifies testbench development by enabling engineers to use a single VIP to verify multiple transmission modes across the full DSI protocol. Synopsys VIP for MIPI DSI is integrated with the Discovery VIP Protocol Analyzer, a protocol-centric debug environment that gives users an easy to understand, graphical view of complex and highly interleaved traffic. Synopsys VIP for MIPI DSI is written entirely in SystemVerilog to run natively in the simulator for optimum performance. Testbench development is accelerated with the assistance of built-in verification plans, example tests and a scenario library. Built-in coverage points integrate with the verification plans showing progress towards achieving coverage goal.
