Overview

Gold standard for Hyperflash memory device for your IP, SoC, and system-level design verification.

Hyperflash in production since 2018 for many production designs.

The Cadence® Memory Model Verification IP (VIP) for HyperFlash provides verification of HyperFlash Controller using the HyperBus protocol. It provides a mature, highly capable compliance verification solution applicable to intellectual property (IP), system-on-chip (SoC), and system-level verification. The VIP for HyperFlash 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 Cypress specification Document Number: 001-99198 Rev. *H Revised February 06, 2017.
