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

Cadence provides a mature and comprehensive Verification IP (VIP) for the ACE specification which is part of the Arm® AMBA® family of protocols. Incorporating the latest protocol updates, the Cadence® Verification IP for ACE provides a framework for system-level coherency, integrated automatic protocol checks, and coverage model. Cadence provides an integrated solution for interconnect verification that supports the verification of coherent interconnect and performance analysis that provides automated generation of testbenches. The VIP provides a mature, highly capable compliance verification solution making it applicable to intellectual property (IP), system-on-chip (SoC), and system-level verification. The VIP for AMBA ACE is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on all leading simulators.

Supported specification: AMBA ACE-Lite, AMBA 5 ACE, AMBA 5 ACE-Lite, AMBA 5 ACE-LiteDVM interfacesת AMBA ACE issues F, G, and H.
