Abstract
An integrated circuit device includes a digital power supply regulation circuit, an analog power supply regulation circuit, a control logic circuit, an analog circuit, and a power supply wiring region. A digital power supply line which supplies a digital power supply voltage and an analog power supply line which supplies an analog power supply voltage are provided in the power supply wiring region. The digital power supply regulation circuit, the analog circuit, and the analog power supply regulation circuit are disposed in a first direction with respect to the control logic circuit. The power supply wiring region is formed along a second direction in a region between the control logic circuit and the digital power supply regulation circuit, the analog circuit, and the analog power supply regulation circuit.
