Abstract :
The widespread use of field programmable gate arrays (FPGAs) as components in high-performance systems has increased the significance of path delay faults in FPGAs. We present a technique for FPGA path delay fault detection which integrates test insertion with the FPGA placement and routing stages to accomplish testing with low test application time. An accurate static timing analyzer is used to identify critical paths and built-in self-test (BIST) hardware is inserted using a placement and routing tool. Initial experimental results show that testing is accomplished with low test application time for several benchmark designs
