SPI

Overview

The VIP environment includes UVM-based components for SPI, QSPI, and OSPI protocols, comprising a Master, Slave, BUS Monitor, and Scoreboard. The BUS Monitor oversees all transfers on the SPI/QSPI/OSPI bus, ensuring adherence to protocol standards. It promptly detects and reports any violations, displaying error messages with detailed causes for corrective action. Additionally, protocol checks are enforced through assertion checking, enhancing the BUS Monitor’s capability.

The VIP fully supports out-of-the-box testing, accommodating DUT slaves or masters seamlessly. It includes various predefined test suites for comprehensive regressive testing. Users also have the flexibility to create custom test cases tailored to specific requirements. With a lightweight design and easy plug-and-play interface, the VIP minimises impact on both design and simulation times, ensuring efficient verification and validation of SPI/QSPI/OSPI implementations.
