Abstract

We present a new automatic test configuration generationtechnique for manufacturing testing of interconnect network ofSRAM-based FPGA architectures. The technique guaranteesdetection of open and bridging faults in all wiring channels andprogrammable switches in the interconnects. Only 8 testconfigurations are required to achieve 100% coverage of stuck-open,stuck-closed, open and bridging faults in theinterconnects of Xilinx Virtex FPGAs.
