Abstract: PROBLEM TO BE SOLVED: To provide a method for designing an integrated circuit, using an idle mode vector. SOLUTION: This method comprises providing of a general list of transistors 27, 28, 29, 31, 32, 33, 34, and 36 of an integrated circuit 20. The transistors of the integrated circuit 20 have initial threshold voltage. The integrated circuit 20 is put in idle operation mode, by applying idle mode vector to inputs 21, 22, 23, and 24 of the integrated circuit 20. The threshold voltages of the transistors 27, 28, 29, 31, 32, 33, 34, and 36 of the integrated circuit 20, which being in 'off' operation mode, block current path to a ground electric potential are set to a threshold voltage higher than the initial threshold voltage. The threshold voltages of remaining transistors 27, 28, 29, 31, 32, 33, 34, and 36 of the integrated circuit 20 are set to a threshold voltage smaller than the initial threshold voltage.
