基于类定向测试的多制式视频后处理芯片验证
Verification for Multi-standard Video Post Processing Chip Based on Resembling Directed Test
摘要
Abstract
In order to cover all the combinations of input and output standard quickly and speed up the verification progress of multi-standard video post processing chip, a verification method of chips based on resembling directed test is proposed by using Constrained Random test(CRT) and Coverage Convergence Technology(CCT) as the guidance, then the essay specifies the process of weight correction in resembling directed test. The simulation data and experimental results show that this approach can improve the rate of hitting the blind spots of coverage, and reduce the repetition of configuration. Accordingly, the coverage of the combinations of input and output standard converges fast, and the efficiency of verification increases by 60% to 70% compared with traditional method.关键词
