Semiconductor test program diagnostic device has packet extraction and display unit for extracting part of test signal based on data fed in by data feed unit and for displaying its contents

摘要

The device has a tester simulation unit for simulating the operation of a semiconductor tester by generating a test signal for a simulation mode based on a test program defined for a packet transfer memory device, a data feed unit for feeding data related to a packet fed into and read out of the memory device. and a packet extraction and display unit for extracting part of the test signal based on the data fed in by the data feed unit and for displaying its contents.
