Abstract
A method for providing a triangularly shaped I/O region on the periphery of an integrated circuit in order to reduce the amount of unused surface area on the integrated circuit is disclosed. A core region within the triangularly shaped I/O region may be either triangularly shaped or rectangularly shaped, and may include one or more metallization lines routed in a direction parallel to at least one edge of the triangularly shaped I/O region on the periphery of the integrated circuit. Alternatively, the core region may include one or more metallization lines routed in a direction parallel to at least one edge of the triangularly shaped peripheral I/O region, as well as one or more other metallization lines routed in a direction perpendicular to at least one edge of the triangularly shaped peripheral I/O region. A plurality of I/O slots located in the triangularly shaped I/O region may be triangularly, trapezoidally, or rectangularly shaped.
