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

Cadence provides a mature and comprehensive Verification IP (VIP) for the Advanced Trace Bus (ATB) specification which is part of the Arm® AMBA® family of protocols. Incorporating the latest protocol updates, the Cadence® Verification IP for ATB provides a complete bus functional model (BFM), integrated automatic protocol checks, and coverage model. Cadence provides an integrated solution for interconnect verification that verifies the correctness and completeness of data as it passes through the system and performance analysis that provides automated generation of testbenches. Designed for easy integration in testbenches at IP, system-on-chip (SoC), and system levels, the VIP for ATB helps you reduce time to test, accelerate verification closure, and ensure end-product quality. The VIP is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on all leading simulators.

Supported specification: AMBA4 ATB v1.0 and v1.1.
