WebFigure 1: stuck-at-0 fault in a circuit 2. At-speed Faults It models the manufacturing defects that behave as gross delays on gate input-output ports. So each port is tested for logic 0-to-1 transition delay (slow-to-rise fault) or logic 1-to-0 transition delay (slow-to-fall fault). WebMultiple Stuck-At Faults Several stuck-at faults occur at the same time For a circuit with k lines there are 2k single stuck-at faults there are 3k-1 multiple stuck-at faults A line could be stuck-at-0, stuck-at-1, or fault-free One out of 3k resulting circuits is fault-free Most Multiple faults are covered by single-fault tests of combinational circuit: hudson valley community services poughkeepsie

WebExample of evaluating the effects of a stuck-at-0 or stuck-at-1 fault. WebExercise 7.1 Suppose that one of the following control signals in the single-cycle ARM processor has a stuck-at-0 fault, meaning that the signal is always 0, regardless of its intended value. What instructions would malfunction? Why? (a) Reg W (b) ALUOp (c) Mem W Exercise 7.2 Repeat Exercise 7.1, assuming that the signal has a stuck-at-1 fault. WebIf a clean logic error (0-to-1, or 1-to-0) is possible, a stuck-at test vector will expose it. That means N and Z values cannot be avoided by using test vectors other than stuck-at … hudson valley community services inc
