Overview

Best-in-class MIPI® UniPro Verification IP for your IP, SoC, and System-Level Design Testing

In production since 2011 on dozens of production designs.

Incorporating the latest protocol updates, the mature and comprehensive Cadence Verification IP (VIP) for the MIPI® UniProsm Protocol provides a complete bus functional model (BFM), integrated automatic protocol checks, coverage model, and compliance tests. Designed for easy integration in testbenches at IP, system-on-chip (SoC), and system levels, the VIP for UniPro helps you reduce time to test, accelerate verification closure, and ensure end-product quality. Our VIP runs on all major simulators and supports SystemVerilog and e verification languages along with associated methodologies, including the Universal Verification Methodology (UVM) and Open Verification Methodology (OVM).

Supported specifications: MIPI UniPro v1.6, v1.8, v2.0, and v3.0 and M-PHY v4.0, v4.1, v5.0, and v6.0.

Product Highlights

  • Compliance: Contains predefined checks to verify that the DUT agents adhere to the protocol rules

  • Error detection: Supports error detection on all layers, more than 200 different protocol checks

  • Coverage: Monitors, checks, and collects coverage on bus traffic using hundreds of automatic protocol checks, including configuration and runtime checks

  • Error injection: Random and predefined error injections promote easy testing of scenarios and scenario creations

  • Environment setup: Configurable environment layers allow for early and specified verification of Data Link Layer

  • Traffic: Generates UniPro traffic on both transaction classes for host and device. Supports constrained-random bus traffic generation

  • Packet tracker creation for easy debugging

  • Callbacks access at multiple TX and RX queue points for scoreboarding and data manipulation

  • Dynamic activation to enable setting the VIP as active/passive during run time
