Document Type and Number:
Japanese Patent JP2917626
Kind Code:
B2
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 source voltage supplying lines. Signal lines of the circuit 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.
