FPGA quality diagnostic test system

An FPGA quality diagnostic test system comprises a hardware circuit and FPGA software logic. The hardware circuit comprises a testing FPGA, a tested FPGA, a PROM, an SRAM, a power supply and configuration circuit, a tested FPGA temperature obtaining circuit, an IO port circuit between the FPGAs, an RS232 port circuit and an SAM output test circuit. The system overcomes the defect that in the prior art, the test coverage of FPGA internal resources is insufficient and is good in real-time performance, high in universality, easy to operation and capable of meeting requirements for an FPGA chip in the test process of an astronautic camera video electronic system.
