Abstract

We introduce the first BIST approach for testingthe programmable routing network in FPGAs. Our methoddetects opens in, and shorts among, wiring segments, and alsofaults affecting the programmable switches that configure theFPGA interconnect. As a result, the BIST technique providescomplete testing of interconnect faults.1
