Detection of a disturbance in the state of an electronic circuit flip-flop

机译:检测电子电路触发器状态中的干扰

摘要

A method and a circuit for detecting a disturbance of a state of at least one first flip-flop from a group of several first flip-flops of an electronic circuit, wherein: the respective outputs of the first flip-flops in the group are, independently from their functional purpose, combined to provide a signal and its inverse, triggering two second flip-flops having data inputs forced to a same state, the respective outputs of the second flip-flops being combined to provide the result of the detection; and a pulse signal comprising a pulse at least for each triggering edge of one of the first flip-flops in the group initializes the second flip-flops.
