Abstract: PROBLEM TO BE SOLVED: To suppress the signal transmission delay time less than its allowable upper limit value by using the 1st and 2nd combinational circuits of low and high voltage sources respectively. SOLUTION: A combinational circuit having its signal transmission delay time less than the designed upper limit value is synthesized with a 1st combinational circuit using a low voltage source 16 of 2V, and a combinational circuit having its signal transmission delay time more than the designed upper limit value is synthesized with a 2nd combinational circuit using a high voltage source 15 of 3V respectively. If the combinational circuits of 2V and 3V coexist in a state where the output of the combinational circuit of a low voltage system serves as the input of a high voltage system, the mapping is performed again to replace 8 logical gate of the next stage including the logical gate serving as the input of the combinational circuit of 3V among the logical gates of 2V with the ogntical gate of 3V constructing a combinational circuit of 3Vlib.  When every register converts its potential level to the output of high voltage from the input of low voltage, the register is mapped onto a flip-flop circuit of a 2V/3V system or a latch circuit of a 2V/3V system.
