摘要
We introduce a methodology for identifying worst case test vectors (WCTVs) for delay failures induced by total dose in sequential circuits implemented in flash-based field-programmable gate arrays (FPGAs) using design-for-testability (DFT) techniques and path delay faults using commercially available DFT and automatic test pattern generation (ATPG) tools. We verified this methodology experimentally using Microsemi ProASiC3 FPGAs and Cobalt 60 facility. The experimental results show a significant impact on the total dose failure level when using WCTVs in total-dose testing of FPGA devices.
