摘　　要：为满足集成电路自动测试设备(ATE)通道间信号同步的需求,基于FPGA提出了一种ATE激励信号传输延时误差的测量方法。该方法硬件结构简单,充分发挥了FPGA与ATE的特性。实验结果表明,该方法的测量结果与示波器测量结果误差在4%以内,能满足激励信号频率小于200 MHz的测量要求。To meet the demand of signal synchronization between channels of integrated circuit automatic test equipment(ATE),a measure method of excitation signal transmission delay error of ATE based on FPGA is proposed.This method has a simple hardware structure and makes full use of the characteristics of FPGA and ATE.Experimental results show that this method achieves an error of less than 4%compared with the measurement result of an oscilloscope,and can meet the measurement requirement of excitation signal frequency of less than 200MHz.
