On multiple-fault diagnosis of baseline interconnection networks
Shun‐Shii Lin, Ferng‐Ching Lin · 1992
A multiple-fault diagnosis procedure which used three distinct test vectors to diagnose a 4*4 baseline network is presented. Multistage interconnection networks are briefly introduced, and the fault model is given. The necessary and sufficient conditions are derived for the input test vectors to diagnose a single switching element. It is proved that six tests are necessary and sufficient to diagnose a 4*4 and an 8*8 baseline network. A multiple-fault diagnosis procedure for an N*N baseline network is presented by using only 2 log/sub 2/ N tests.>
