基于uvm验证方法学的盲均衡器验证

摘要

文章采用通用验证方法学（UVM）搭建验证平台，以高速光纤传输系统中的数字信号处理芯片的盲均衡器作为验证对象，重点分析了UVM验证平台的搭建思想，产生随机化的测试向量，对盲均衡器进行全面验证，从而达到覆盖率的要求，通过寄存器模型和自动化脚本的使用，提高验证效率和平台的可重用性。验证结果表明，通过这种面向对象的层次性建模方法，可以大幅缩短平台的维护和开发时间，采用该验证方法的功能覆盖率为100%，代码覆盖率为98%，翻转覆盖率为97%。%Based on blind equalizer in DSP in high-speed optical transmission system,UVM is described in this paper.By generating a large number of randomized stimuli in the verification platform,this paper verified the blind equalizer and ulitimately achieved the coverage requirements.By the RAL and automation script,this paper can improve veriifcation efifciency and reuseablity.The veriifcation result show that the OOP hierarchical modeling method can save a lot of platform maintenace and development time,the function coverage can be reached 100%,the code coverage can be achieved 98% and toggle coverage can be reached 97% using the proposed method.
