A verification method for DMA controller based on AHB bus

Abstract： A verification method based on AHB bus DMA controller is proposed to address the problems of traditional chip verification platforms, poor reusability of verification cases, and long verification time. The validation platform modified and optimized through this method has high portability, with the ability to simulate the generation of request, reply, and interrupt signals through IP linkage, and supports the ability to randomly inject errors into the AHB bus during transmission. To demonstrate the effectiveness of the method, the architecture of the DMA controller UVM verification platform was modified and optimized, and the platform was reused to construct the Image2D controller UVM verification platform. The code coverage of two verification platforms was collected separately. The experimental results show that this method can improve the debugging and debugging speed of the verification platform, enhance the compatibility of the verification platform, save more than 15% of the verification development time, and ensure 100% code coverage of the verification platform.
