Abstract
In an integrated circuit in which function blocks constituting a CPU block, a memory block and the like, a power supply line for supplying power to the function blocks, and multiple signal lines for inputting and outputting signals to and from the function blocks are formed on a semiconductor substrate, bypass capacitors are provided on the power supply line in proximity to or inside the function blocks. The capacitances of these bypass capacitors are set in correspondence with the consumed current characteristics of the respective function blocks. As a result, noise produced on the power supply line by the operation of the function blocks can be suppressed and it is possible to certainly prevent such noise from leaking out through power supply terminals and input/output terminals of the integrated circuit to the outside.
