Due to programmable feature of FPGAs, faults of FPGAs can be easily tolerated if fault sites can be located. A hardware/software (HW/SW) co-verification technique for FPGA test is proposed in this paper. Taking advantage of flexibility and observability of software in conjunction with high-speed simulation of hardware, this technique is capable of testing each input/output block (IOB) and configurable logic block (CLB) of FPGA automatically, exhaustively and repeatedly. Fault cells of FPGA can be positioned automatically by the proposed approach. As a result, test efficiency and reliability can be enhanced without manual work.展开更多
