ERROR DETECTION SYSTEM APPLICABLE TO RTL MODULE AND OPERATION METHOD THEREOF

Abstract: an operation method of an error detection system includes: outputting a first electrical signal in response to one input, by a first functional block, and outputting a second electrical signal in response to the one input, by a second functional block performing the same function as the first functional block; comparing the first electrical signal and the second electrical signal to check whether there is an error in the first functional block or the second functional block, and outputting a first comparison result and a second comparison result, by a first comparator and a second comparator; and confirming an error in either the first functional block or the second functional block or confirming an error in either the first comparator or the second comparator based on the first comparison result and the second comparison result, and outputting an error report signal or a latent fault report signal according to a confirmation result.
