1. A device, comprising:
a first supply voltage track configured to provide a first voltage;
a second supply voltage track configured to provide a second voltage that is greater than the first voltage;
a first reference track;
a first standard cell configured to be electrically connected to the first supply voltage track to receive the first voltage and electrically connected to the first reference track;
a second standard cell configured to be electrically connected to the second supply voltage track to receive the second voltage and electrically connected to the first reference track;
a first library including the first standard cell configured to be electrically connected to the first supply voltage track to receive the first voltage and electrically connected to the first reference track; and
a second library including the first standard cell configured to be electrically connected to the second supply voltage track to receive the second voltage and electrically connected to the first reference track.
