Abstract
A method of designing a semiconductor integrated circuit, comprises: replacing a circuit element disposed in the semiconductor integrated circuit with a transistor having a high threshold value or a circuit element having a small juxtaposition number in order to prevent deviation of a signal voltage flowing through the semiconductor integrated circuit from a power voltage and a ground voltage; replacing a circuit element disposed in a subsequent stage of the replaced circuit element in order to prevent the deviation of the signal voltage from the power voltage and the ground voltage from being propagated to a subsequent stage with a transistor having a high threshold value or a circuit element having a small juxtaposition number; and then arranging circuit elements constituting the semiconductor integrated circuit in such a manner that the semiconductor integrated circuit stably operates.
