UVM Verification of MAC Based on Functional Coverage

论文基于UVM验证方法学,以及覆盖率驱动的芯片验证指导思想,搭建并分析了高度可重用的以太网控制器IP的验证平台。为了提高验证效率,论文对MAC的工作流程进行了研究,对其功能点进行了划分,针对性地编写了测试用例。在测试用例的驱动下,对MAC的数据收发功能进行了全流程的仿真验证。在大规模随机测试用例和定向测试用例的共同作用下,加快了验证所需要的时间,节省了仿真所需的计算机资源,达到了功能覆盖率100%的目标。

Based on UVM verification methodologies and coverage-driven chip verification guidelines,this article builds and analyzes a highly reusable Ethernet controller IP verification platform.In order to improve the verification efficiency,this paper stud⁃ies the MAC's workflow,divides its function points,and writes test cases targeted.Driven by test cases,the entire process of MAC data transmission and reception is simulated and verified.Under the combined effect of large-scale random test cases and directed test cases,the time required for verification is accelerated,the computer resources required for simulation are saved,and the goal of 100%functional coverage is achieved.
