摘　　要：针对带有异步接口的CAN控制器,设计实现了一种基于UVM的随机化、可重用的功能验证平台。该平台使用面向对象的UVM类搭建,代码可重用性更强,开发周期更短;引入随机化程度更高的激励加快功能验证的收敛速度,且更加贴近芯片的实际应用场景;自动化比对机制可以实时地输出结果报告,便于问题的定位和调试。平台独创性地实现了CAN总线代理器和异步接口驱动器两个组件,兼容CAN 2.0B标准协议和Intel/Motorola异步接口时序,实现了平台与DUT的数据交互。实验结果表明,设计验证平台可以有效验证待测设计异步接口CAN控制器。For Controller Area Network(CAN)controller with asynchronous interface,a randomized and reusable function verification platform based on Universal Verification Methodology(UVM)is designed and implemented.The platform is built using object-oriented UVM classes.The code is more reusable and the development time is shorter.The introduction of a more randomized incentive accelerates the convergence speed of functional verification,and the random incentive is closer to the actual application of the chip.The automatic comparison mechanism can output the result report in real time,which is convenient for problem debugging.The platform has creatively implemented two components,CAN bus agent and asynchronous interface driver,which realized the CAN 2.0B protocol,as well as the Intel/Motorola asynchronous interface timing,so that the platform can communicate with the Design Under Test(DUT).The experimental results show that the verification platform can effectively verify the asynchronous interface CAN controller to be tested.
