Title: Parity tree circuit
Inventor: MATSUOKA KOUJI
IPC: G06F11/10
Filed: 1983-12-12
Abstract: PURPOSE:To attain an own test performance parity tree circuit detecting all kinds of a single fault in the circuit by forming the parity tree circuit as serial multi-stage connection form of two-input exclusive OR circuits and adding one input controlled independently from an external part. CONSTITUTION:Circuits 3 are each made up of exclusive logical OR circuits EX-OR, which are connected in series as multi-connection. One input of each EX-OR circuit 3 is one element of inputs Y and the other is an output of the EX-OR circuit of the pre-stage or an external control signal A. That is, in inputting the external control signal A, one more stage of the EX-OR circuits 3 is required additionally. Then an output value of an optional circuit stage is changed by changing the external control circuit A. Thus, a fault of an output ti of the circuit stage and a fault in the input yi are propagated to an output stage of the parity tree circuit 2' so as to invert the value of output tk. If a fault of stuck-at-0 takes place in the circuit output ti, the value of the external control signal A is controlled so as to form an odd number of 1s in the inputs A, y0, y1,...yi-1, thereby detecting the fault.
