Diagnostic and Detection Fault Collapsing for Multiple Output Circuits [PDF]
Design, Automation and Test in Europe, 2005 We discuss fault equivalence and dominance relations for multiple output combinational circuits. The conventional definition for equivalence says that "Two faults are equivalent if and only if the corresponding faulty circuits have identical output functions".
