Abstract
An optimum stage number calculation method executed by a processor, the optimum stage number calculation method includes extracting information on a signal path between a transmission cell and a reception cell that transmits and receives a signal according to a clock from net information indicating a connection relationship between a plurality of cells arranged and wired in a field programmable gate array, estimating a cell total delay amount indicating a total delay amount of cells allowed to be included in one period of the clock in the signal path from input information including at least clock period information indicating a length of one period of the clock, calculating the number of stages of logic cells included in the signal path from the cell total delay amount, and outputting number-of-stages information indicating the calculated number of stages of the logic cells.
