Study on Test Method of FPGA Circuit Board based on DFT

With the continuous development of microelectronic technology,more and more complex logic devices are applied to the circuit board of weapons equipment.It makes the growing complexity of the circuit board structure and function,and the traditional method can not be effective for that type of circuit board test.Detection of the circuit board is increasingly prominent.Thus,in the beginning stages of the design of electronic equipment,the technology of the design for testability is introduced.Therefore,for the FPGA circuit board,a test method based on DFT is studied.
