Abstract:An approach for detecting open and short faults on the interconnect wires of a multi-FPGA system will be presented in this paper. In a multi-FPGA system with N interconnects, this approach can detect whether and where an open fault occurs by executing the IEEE 1149.1 JTAG EXTEST instruction once. To detect a single short fault, on the other hand, needs execution of times where . If multiple short connections exist, this approach will only detect the first short fault. The test time is thus greatly reduced for … Show more
