UVM-Based Verification of AMBA AHB-To-APB Bridge Using Modularized Interfaces and Reactive Slaves

Abstract This paper presents a high-level verification environment for the Advanced High-performance Bus (AHB) to Advanced Peripheral Bus (APB) bridge design using the UVM framework. In the verification model, we apply two advanced techniques including modularized interface and reactive slave to create an accurate, automated, and completely reusable testing environment. A detailed test plan with the full functions of the AHB and APB was built to verify the AHB-to-APB bridge design. The verification component (VC) of the AHB and APB has been developed and extended for the testbench. Therefore, the testbench can be reused while still ensuring each VC is separate and connected to the interfaces using the interface modularization method. The scoreboard is also meticulously developed to check designs automatically. The experimental result shows that the functional and toggle coverage scores are achieved up to 100% and 92%, respectively.
