Filed: 1995-02-17
Abstract: PURPOSE: To attain the handling of a large scale logic circuit and also to fast verify a timing error by carrying out the timing check by dividing the verification processing into two steps. CONSTITUTION: A file 5 holding the initial timing check reference value is inputted to a computer 1, and a 1st timing verification processing means 11 checks the 1st step of the timing verification based on the initial timing check reference value. A 2nd timing verification processing means 12 generates the check reference value of high accuracy to carry out the 2nd step of the timing verification against the flip-flop which is decided as error, by the check of the means 11. As the result, an activated path of the flip-flop having an error is acquired by the back trace. The logical value and the delay value of an element put on the activated path are stored in a file 8. An analysis support processing means 13 generates the timing analysis information based on the accumulated information and shows the information on a display 9.  Thereby, a user individually analyzes the factors of the timing error.
