Abstract

The invention provides a method and a device for testing a chip. The method is used for automatic test equipment (ATE) and comprises the following steps of: reading a test vector source file in a memory of the ATE, and displaying a list of pin description information in the test vector source file; deleting pin description information, which is not actually input or output, in the list by using a deletion module of a source file editor; storing the modified test vector source file; and operating the modified test vector source file by using the ATE to test the chip, so that resources occupied by the pin description information which is not actually actual input or output in the test are saved. By the method and the device, the resources of the ATE can be saved, test efficiency is improved, and the technical problems that the test vector source file consumes a large quantity of time and resources and the test efficiency is low in the prior art are solved.

Description

technical field [0001] The invention relates to automatic testing equipment for chips, in particular to a chip testing method and device. Background technique [0002] ATE (AutomaticTestEquipment, automatic test equipment), is a device, circuit board and chip testing equipment controlled by a computer. It replaces manual labor through computer programming and automatically completes the test sequence. [0003] ATE can be divided into the following types: digital test system, linear device test system, analog test system, memory test system, board test system, mixed signal test system, SOC (System on Chip, integrating a complete system in a chip) test system. [0004] The development of ATE is from simple devices, low pin count, low speed test system (10MHz, 64pins) to medium pin count, medium speed test system (40MHz, 256pins) to high pin count, high speed (over 100MHz, 1024pins) and Finally transitioned to the current SoC test system (1024pin, over 400MHz, and has simula...
