PROBLEM TO BE SOLVED: To enable a designer to perform rearranging work with high efficiency by clearly displaying information about a critical path in a state the arrangement position of a block is changed/corrected. SOLUTION: An LSI arranging method has a step S1 for reading circuit information as read information, a step S2 for displaying the arrangement information of the block on the basis of the read information, a step S3 for selecting one unarranged or arranged block, a step S4 for temporarily and provisionally arranging the selected block at a desired arrangement place, a step S5 for performing a simple delay calculation to calculate a wiring delay value, a step S6 for comparing the delay value obtained in the step S5 with a delay constraint value and recognizing wiring in which the delay value is larger as a critical path to display the wiring, a step S7 for deciding whether a block position is proper on the basis of critical path information, a step S8 for making the a block arrangement position a determined position, and a step S9 for deciding whether all blocks have been arranged and finishing the processing in the case no unarranged block exists.
