摘要
集成电路测试系统测试通道传输延迟时间测量过程中,受边界条件影响,测量信号的回波出现部分信号丢失的情况,直接影响测量结果。通过差分定位算法,进行一次补充测量,可以恢复丢失的回波信号,给出准确地传输延迟时间测量结果。论文通过实验,验证了差分定位算法技术可行,结果准确度较高。
During the measurement of transmission delay time in automatic test system,influenced by the boundary condition,the echo is partially lost,which directly affects the measurement result.By using differential positioning algorithm and implementing a supplementary measurement,the lost echo signal can be recovered,and the result of transmission delay time measurement can be accurately given.Through experiments,this paper proves that the differential positioning algorithm is feasible,and the results are accurate.
