摘　　要：针对传统芯片验证平台验证用例复用性差、验证时间长的问题,提出了一种基于AHB总线DMA控制器验证方法。通过该方法修改优化的验证平台可移植性高,具有模拟联动IP产生请求、回复与中断信号的功能,支持在传输中对AHB总线随机注入错误的能力。为证明方法的有效性,对DMA控制器UVM验证平台架构进行修改优化,并复用该平台构建Image2D控制器UVM验证平台,分别收集两个验证平台代码覆盖率。实验结果表明,该方法能够提高验证平台调试排错速度,提升验证平台兼容性,节约15%以上的验证开发时间,并保证验证平台代码覆盖率为100%。A verification method based on AHB bus DMA controller is proposed to address the problems of traditional chip verifi‐cation platforms,poor reusability of verification cases,and long verification time.The validation platform modified and opti‐mized 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.
