Chip testing system and method

Abstract

The invention provides a chip testing system and method, and the system comprises a receiving conversion chip and a processor, the receiving conversion chip is connected with the processor, the receiving conversion chip is used for being connected with a to-be-tested chip during the testing of the to-be-tested chip, the receiving conversion chip comprises an analysis module and a verification module, and the analysis module and the verification module are connected with each other. The analysis module is used for analyzing to obtain video image data according to the video image signals and extracting actual video image parameters of the to-be-tested chip, the verification module is used for calculating to obtain actual cyclic redundancy verification values of the to-be-tested chip according to the video image data, and the processor is used for processing the actual video image parameters, the actual cyclic redundancy verification values and the actual cyclic redundancy verification values to obtain the to-be-tested chip. And comparing the predefined video image parameter with the predefined cyclic redundancy check value to obtain a test result. Therefore, the chip test result is accurately obtained, and the chip does not need to be converted through a signal, so that the test cost and the test time are saved. The method does not need an FPGA, reduces the starting time, is high in calculation speed, and is high in error detection capability.

Description

technical field [0001] The present application relates to the field of chip testing, in particular to a chip testing system and method. Background technique [0002] The MIPI alliance is the mobile industry processor interface (Mobile Industry Processor Interface, MIPI for short) alliance. MIPI is an open standard and a specification for mobile application processors initiated by the MIPI Alliance. [0003] There are different working groups under the MIPI Alliance, which define a series of mobile phone internal interface standards, such as serial camera interface (CSI, Camera Serial Interface), serial display interface (DSI, Display Serial Interface), radio frequency interface, etc. The advantage of a unified interface standard is that mobile phone manufacturers can flexibly choose different chips and modules from the market according to their needs, making it faster and more convenient to change designs and functions. [0004] CSI defines a high-speed serial interface be...

Problems solved by technology

Such a test method adds a signal conversion chip, which increases the test cost and test time, increases the difficulty and time of hardware debugging, and needs to be tested with the help of FPGA, the price of FPGA chips is high, and it is necessary to learn related programming knowledge and Only those who understand FPGA can complete relevant tests. Compared with the present invention, the existing test methods are slow to learn, difficult to debug, high in cost, long in test time, and long in chip mass production cycle.
