Abstract

The invention discloses a chip pin connection relation detection method and system. The method includes the following steps of acquiring a chip schematic diagram file and a pin constraint file, constructing a matching relation table, editing a merge file which comprises chip pin information shown in a chip schematic diagram and chip pin information shown in the pin constraint file at the same time according to the chip pin connection relation shown in the chip schematic diagram and the pin constraint file, detecting the actual chip pin matching situation according to the chip pin matching relation shown in the merge file and outputting the matching result to an object file. According to the chip pin connection relation detection method and system, computers replace people to detect the corresponding connection relation of physics pins in the chip schematic diagram and electric signals, a large amount of time is saved, and misoperation probably caused by repetitive work is avoided. If a new pin matching relation exists, only the corresponding matching relation table needs to be extended, and therefore the chip pin connection relation can be automatically detected.

Description

technical field [0001] The invention relates to the field of detection methods, in particular to a method and system for detecting the connection relationship of chip pins. Background technique [0002] In order to ensure the normal operation of the computer system, when the integrated circuit chip is manufactured, it is necessary to check whether the physical pin and signal connection relationship of the chip is consistent with the designed chip principle. Figure 1 To carry out inspection. In the prior art, whether the relationship between the physical pins of the chip and the signal connection is consistent with the designed chip principle Figure 1 Consistency detection needs to be carried out manually. Since the number of chip pins is very large, it takes a lot of time for a large amount of information such as the connection properties and pin constraints of the chip pins during the detection process, and the correctness of the detection cannot be guaranteed. sex. When...
