Abstract
An integrated circuit may include a plurality of input/output (I/O) cells used for communicating signals, power, and ground to and from a core of the integrated circuit. The I/O cells may each include a bond pad formed in one or more top metal layers. One or more of the bond pads may be offset a predetermined distance from an I/O cell edge corresponding to a chip edge of the integrated circuit. A volume may be determined by the I/O cell edge and the predetermined distance and one or more rails may be disposed in the volume and in at least one metal layer common with at least one metal layer of the bond pad. The rails may be involved in the discharge of electrostatic discharge (ESD) current, and may reduce path resistance of the path used to discharge the ESD current.
