PROBLEM TO BE SOLVED: To efficiently identify a node where timing is off after a circuit is changed. SOLUTION: The timing analysis device is provided with: a reference circuit data reading means 12 for reading a net list and timing information of a reference circuit used as a reference of comparison from the libraries 4 and 6 of the reference circuit; a revised-version circuit data reading means 14 to read the net list and timing information of the revised-version circuit which is at least partially different from the reference circuit, from libraries 8 and 10 of the revised-version circuit; a timing restriction reading means 16 for reading timing restriction common to both circuits; analysis means 18 and 20 for analyzing the timing of each circuit on the basis of the read timing restriction; and means 32 and 34 which output a reference circuit timing report showing analysis result data obtained by the analysis means for the reference circuit and a revised-version circuit timing report showing analysis result data obtained by the analysis means for the revised-version circuit, side by side.
