Adopting Universal Verification Methodology to Achieve Reusability and Automation Verification

在分析UVM的基础上,重点研究了验证的可重用与自动化实现方法.重用体现在验证组件的横向、纵向重用实现和验证场景的继承、组合重用实现.自动化实现依赖平台构建时的Field-Automation机制、脚本控制的RAL模型生成以及平台运行时的仿真结果实时在线比对等.最后,以PCI Express Controller的验证工作为例,说明了如何以自动化和重用性方法为指导,快速构建结构化的UVM验证平台,实施功能验证.验证结果表明,基于自动化与可重用的验证方法能够显著提升验证效率.

Based on the analysis on UVM , this paper focuses on the implementation method of reusability and automation .The reusability is reflected by the horizontal and vertical reuse of verification components and the inheritance and combined reuse of verification scenarios . Automation implementation relies on Field-Automation mechanism ,script-controlled RAL model generation at platform constructing phase and the simulation results real-time compare online at platform running phase .Finally ,the PCI Express Controller verification has been completed to illustrate the method of building the structured UVM verification platform rapidly guided by automate and reuse approach .Verification results show that the automation and reusability implementation method can significantly improve verification efficiency .
