Simulation VIP for NVMe

Overview

The Cadence® Verification IP (VIP) for NVMe is part of Cadence's storage interface VIP portfolio. It provides a mature and highly capable compliance verification solution for the NVM Express (NVMe) protocol. It is applicable for IP, SoC, and system-level verification. The VIP is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on the Cadence <a href="/en_US/home/tools/system-design-and-verification/simulation-and-testbench-verification/xcelium-simulator.html">Incisive™ Enterprise Simulator</a> as well as on third-party simulators.

The Cadence VIP for NVMe seamlessly integrates with Cadence VIP for PCI Express® for all generations (1.0, 2.0, 3.0, 4.0, 5.0, and 6.0), it supports NVMe over AXI verification and NVMe stand-alone verification.

Supported specification: NVMe Specification Revisions 2.0, 1.4, and 1.3.
