Chip validation method and device and system based on field programmable gate array (FPGA)

Abstract

The invention belongs to the field of chip validation and provides a chip validation method and a device and a system based on field programmable gate array (FPGA). The chip validation method based on the FPGA comprises the steps that source data are generated randomly according to a preset test program, the source data are used for generating result data after being processed in a displaying mode through a liquid crystal display (LCD) module to be tested, reference data are generated according to the source data, the result data are monitored, the result data after being monitored are compared with the reference data, and verification results are output. According to the chip validation method and the device and the system based on the FPGA, the LCD module is verified by the source data generated randomly, coverage rate of the validation is improved, a monitoring unit is adopted to replace an LCD screen to monitor the result data output by the LCD module and to compare the result data with the reference data, automatic validation is achieved, objectivity of the validation is improved, and precision of the validation is also improved.

Description

technical field [0001] The invention belongs to the field of chip verification, and in particular relates to an FPGA-based chip verification method, device and system. Background technique [0002] In a system on chip (SOC, system on chip) multimedia processing chip, a liquid crystal display (LCD) module is generally integrated to control the display of a liquid crystal display (LCD, Liquid Crystal Display) in a multimedia device, and its display effect directly affects the The promotion and application of multimedia equipment, so it is particularly important to provide a complete LCD module. [0003] The quality of LCD modules is generally guaranteed by various verification methods, among which Field Programmable Gate Array (FPGA, Field Programmable Gate Array) verification is a relatively common and important verification method. In the existing FPGA verification environment, LCD modules The verification method is: at first, the video data to be displayed is placed in the...
