Abstract:
A method for laying out an electronic circuit, said method comprising:the first step of inputting a net list of an electronic circuit as a design target, and setting a plan of a layout from said net list; the second step of inputting a structure of each wire and an electrical characteristic of a circuit element connected to said wire, on the basis of said net list; the third step of inputting a condition for a circuit element connected to a terminal end of said wire to operate normally; the fourth step of calculating a maximum wire length that ensures to operate normally, using parameters input in said second step and said third step; the fifth step of comparing a wire length based on the plan of said layout and said maximum wire length; the sixth step of again setting a plan of an layout in case that the wire length based on the plan of said layout is longer than said maximum wire length as a result of comparing in said fifth step; wherein said second step inputs a dielectric constant of a substrate, a path impedance of the wire, and impedances of circuit elements connected to both ends of said wire.
