基于UVM的存储控制器功能验证

采用通用验证方法学(UVM)搭建验证平台,以AHB总线上挂载的存储控制器为验证对象,重点分析了UVM验证平台的设计。采用传统的定向验证方法将很难遍历到所有情况,而通过UVM验证平台能够产生受约束的随机激励信号,对存储控制器进行全面的验证,并能自动收集功能覆盖率和分析验证结果。验证结果表明,该验证平台能有效地查出设计缺陷,达到覆盖率要求,减少验证时间,提高验证效率,且具有良好的可配置性和可复用性。

Functional verification of memory controller based on UVM

This paper constructs a verification platform using UVM based on the memory controller mounted in the AHB bus. The design of UVM verification platform is emphasized. Using traditional directional verification method will be difficult to traverse all cases. Nevertheless, generating constrainted random stimuli through UVM verification platform can thoroughly verify the function of memory controller , also it can collect functional coverage and analyze results automatically. Verification results report that, this verification platform can efficiently find out bugs in design, fulfill coverage requirement, shorten verification time, improve verfication efficiency with excellent configurability and reusability.
