Abstract

The invention discloses an automatic testing device and method universally used for multiple bus processor modules. The automatic testing device comprises a power supply unit, wherein the power supply unit is connected with an industrial personal computer, a programmable oscilloscope, a programmable power supply and a signal acquisition subdevice; the industrial personal computer is connected with an equipment access box, an equipment adapter box is respectively connected with a multimeter and a digital I / O (Input / Output) control panel, the power supply input end of the equipment adapter box is connected with the power supply output end of the programmable power supply; the industrial personal computer is connected with the programmable oscilloscope, the programmable power supply and a communication board; and the programmable oscilloscope and the programmable power supply are connected with the equipment adapter box. The invention mainly realizes portable mechanical loading of different types of different bus processor modules, automatic loading of closed test programs, automatic testing of performances and breakage and short circuit property tests of all pins of the module. By using test hardware of the automatic testing device and matching developed test software, automatic recognition of the processor modules, automatic loading of the closed test programs, real-time display of performance test results, report output and other functions can be realized.

Description

technical field [0001] The invention relates to a multi-type, multi-bus module testing device, in particular to a multi-bus processor module universal automatic testing device and a testing method designed based on virtual instrument technology. Background technique [0002] At present, for processor module manufacturers, in the design and production process of the processor, the method adopted is to design a motherboard for the processor module of a bus. During the test, the motherboards with different buses are selected according to the different buses of the modules under test. This design scheme lacks versatility, and it requires the manufacturer of the processor module to be familiar with the timing relationship of the bus of the processor. For some manufacturers, due to the preservation of files and files, many original information about the motherboard have been found. Gone, performance testing of production processor modules is not possible if there is a problem wit...
