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

Cadence provides a mature and comprehensive Verification IP (VIP) for the Advanced Peripheral Bus (APB) specification which is part of the Arm® AMBA® family of protocols. Incorporating the latest protocol updates, the Cadence® Verification IP for APB 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 APB helps you reduce time to test, accelerate verification closure, and ensure end-product quality. Cadence provides a solution for interconnect verification that verifies the correctness and completeness of data. The VIP is compatible with the industry-standard Universal Verification Methodology (UVM) and runs on all leading simulators.

Supported specification: AMBA 2 APB, AMBA 3 APB, and AMBA 4 APB specifications.
