Abstract
A timing error analysis method includes, extracting, from error information, a design value related to a delay amount of a signal path and a feature that is an input when a machine learning model learns with the design value as an output, estimating a correct answer value of the design value from the feature and the machine learning model learning a relationship between the design value and the feature, comparing the design value with the correct answer value and storing a comparison result, generating a comparison result list including countermeasures for eliminating the timing error according to the comparison result, aggregating signal paths included in the comparison result list for each design block to generate an error list including information indicating the signal paths aggregated for each of the design blocks and the countermeasures, and outputting the error list.
