Simulation VIP for Q-SPI

Overview

In production since 2018 for many production designs.

The Cadence® Verification IP (VIP) for Quad SPI provides verification of Q-SPI NOR devices using the SPI protocol. The VIP for Q-SPI is compatible with the industry-standard Universal Verification Methodology (UVM), runs on all leading simulators, and leverages the industry-standard Cadence Memory Model core architecture, interface, and use model.

Supported Specification: Features of all major vendors such as Micron, Macronix, Winbond, Cypress, GigaDevices, and ISSI.
