Abstract
An integrated circuit with a power layout includes at least one power grid cell. Each power grid cell includes a first power layer configured to be electrically coupled to a first power supply voltage, and a second power layer separate from the first power layer and configured to be electrically coupled to a second power supply voltage different from the first power supply voltage. The first power layer has conductive lines configured to surround a conductive element electrically connected to the second power layer.
