Abstract: An integrated circuit includes a core domain having at least one core domain design rule limitation of a smaller device and a lower operating voltage, an input/output domain having at least one input/output domain design rule limitation of a larger device than the smaller device of the core domain and a higher operating voltage than the lower operating voltage of the core domain, and a mapping cell that includes two or more electrical devices that each meet the at least one core domain design rule limitation. The mapping cell is configured to be an input/output device and operate in the input/output domain at the higher operating voltage of the input/output domain.
