ABSTRACT:
A semiconductor integrated circuit device is provided which comprises circuit blocks driven at different power source voltages and voltage level converting circuits for converting the voltage level of a signal between these circuit blocks. Power source voltage supplying lines are disposed at an area corresponding to a wiring region provided between an internal circuit region and interface region formed on a semiconductor substrate, and a larger number of voltage level converting circuits than that necessary for the integrated circuit are disposed along the blocks are connected to the voltage level converting circuits of a necessary number for the integrated circuit. The time required for layout designing can be reduced and an error due to layout designing is difficult to be generated.
