一种基于UVM加快功能验证收敛的方法

A Method of Speeding up Convergence Functional Verification Based on UVM

功能验证是IC设计最重要的步骤之一。随着设计复杂度的增加,定位缺陷成本也日益增加,许多设计验证团队将相当一部分精力放在高效验证过程开发上。文中以航电CNI系统主机接口模块功能验证为例,采用基于统一覆盖率验证管理技术、UVM验证技术、接口时序断言监控技术,分别从验证计划制定、平台搭建、验证管理与验证结果分析等方面,介绍一种新型的基于统一覆盖率加速功能验证收敛的闭环验证方法。结合UVM验证方法学和断言技术,详细论述构建一种高效率可重用、快速收敛的验证平台的过程。

Functional verification is one of the most important steps in the IC design. With the increase of design complexity,the cost of locating defects is also raised. Many designers will be a great deal of efforts on the development of efficient verification. In this paper,a new type of closed-loop verification method based on uniform coverage is introduced,taking functional verification of the host interface module of CNI system as example,using authentication management technology based on uniform coverage, UVM verification technolo- gy, and monitoring interface timing assertions respectively from the verification plan, platform building, management and authentication results analysis,etc. The process of constructing an efficient,reusable and fast convergent verification platform is discussed in detail by combining UVM verification methodology and assertion technology.
