摘要：
An object of the present invention is to provide a semiconductor integrated circuit that reduces the influence of noise from a digital circuit block on an analog circuit block, both the circuit blocks being integrated on the same semiconductor substrate. In the wiring that passes through near the analog circuit block and the digital circuit block, having a grounding unit that performs alternate grounding makes it possible to reduce the influence of noise from the digital circuit block on the analog circuit block.
