Abstract

The invention discloses a FPGA (Field-Programmable Gate Array) self test method and device, which relate to the technical field of electronic and automatic test. The method comprises steps: a test single board configured with an FPGA chip and capable of operating an FPGA program receives an FPGA test file sent by a PC and an FPGA version; through loading operation of the FPGA version, the test single board generates an FPGA test version capable of operating the FPGA test file; and through operating the FPGA test version by the test single board, multiple function units for automatically executing various test tasks in the FPGA test file are formed, test is performed, and the test results are returned to the PC. Self test on an FPGA logic circuit in a real scene and a real processing time sequence can be carried out, and the self test result is more credible.

Description

technical field [0001] The invention relates to the technical field of electronics and automatic testing, in particular to a method and device for FPGA (Field-Programmable Gate Array, Field Programmable Gate Array) self-testing. Background technique [0002] Due to its rich interface resources and flexible and fast programmable features, FPGA can customize a dedicated integrated circuit to make up for the lack of commercial chips and meet the special functional requirements of users. Therefore, it has a wide range of applications in communication, multimedia, information processing and other fields. [0003] In the development and application of FPGA, the test and verification of logic function is a very important step. Traditional FPGA testing and verification is mainly done through simulation. Commonly used simulation methods include: using simulation tools integrated into compilation software provided by FPGA manufacturers, or using special simulation tools developed by ...
