| 摘 要： | 采用通用验证方法学（UVM）搭建验证平台,以Sigma-Delta A/D转换器中的数字抽取滤波器为验证对象,重点分析UVM验证平台的设计方法.利用该UVM验证平台,产生随机化的测试向量,对数字抽取滤波器模块进行全面的验证,最终达到覆盖率要求.通过与传统定向测试平台的验证结果对比,可以得出使用通用验证方法学的验证效率与验证能力更高.

| Abstract: | Based on the digital decimation filter in Sigma-Delta ADC, UVM is described in this paper.By generating a large number of randomized stimuli in the verification platform, this paper verified thefunctions of the filter and ultimately achieved the coverage requirements. Compared with traditionaldirected test, it can be seen that UVM has higher efficiency. |
