Abstract

The circuit simulator stores an information representing a relation between the level transition on an output signal of each element in an object circuit and an input terminal to which a test pattern is applied. When a timing error occurs, an error message outputted based upon the information facilitates to narrow down the range of subjects to be analyzed for seeking the cause of the error, whereby the cause of a timing error can be easily cleared up.
