Abstract
An electronic device and an operating method therefor are disclosed. The electronic device according to at least one of various embodiments of the present disclosure comprises: a memory; a semiconductor device including a functional block, which outputs a result of a specific function performed on an input signal, and a functional safety block, which is for a safety mechanism determining whether the functional block is faulty; and a processor for determining whether the semiconductor device is faulty, wherein the functional safety block can include constituent elements that are the same as pre-configured constituent elements from among constituent elements of the functional block.
Claims13
An electronic device comprising:
- a memory;
- and
- a semiconductor device including a functional block comprising at least one combinational logic and at least one flip-flop, the functional block configured to output a result obtained by performing a function based on the at least one combinational logic on an input signal, and a functional safety block for a safety mechanism configured to detect a fault in the functional block and comprising at least one duplicate flip flop corresponding to the at least one flip flop of the functional block without duplicating the at least one combinational logic;
- and
- a processor configured to determine whether the semiconductor device has a fault based on a fault detection result from the functional safety block,
- wherein the fault detection result is based on a comparison of an output value of the at least one flip flop of the functional block given an input value with an output value of the at least one duplicate flip flop of the functional safety block given the same input value.
