Best-in-class Arm® AMBA® AXI Verification IP (VIP) for your IP, SoC, and system-level design testing.

Cadence provides a mature and comprehensive Verification IP (VIP) for the AXI specification which is part of the Arm® AMBA® family of protocols. Incorporating the latest protocol updates, the Cadence® Verification IP for AXI provides a complete bus functional model (BFM), integrated automatic protocol checks, and coverage model. Designed for easy integration in testbenches at IP, system-on-chip (SoC), and system levels, the VIP for AXI helps you reduce time to test, accelerate verification closure, and ensure end-product quality. Cadence provides an integrated solution for interconnect verification that verifies the correctness and completeness of data as it passes through the SoC and performance analysis that provides automated generation of testbenches. The 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 specification: AMBA 3 AXI, AMBA 4 AXI, AMBA 4 AXI-Lite, AMBA 5 AXI, and AMBA 5 AXI-Lite interfaces, AMBA AXI issues F, G, and H.
