Abstract
Systems and methods are disclosed for pad ring generation for integrated circuits. For example, a method may include accessing a pad ring configuration data structure, wherein the pad ring configuration data structure declares rules for inputs and outputs of an integrated circuit using a scripting language; based on the pad ring configuration data structure, automatically generating an integrated circuit design data structure that encodes a physical design for the integrated circuit that includes a pad ring with bumps satisfying the rules for inputs and outputs of the integrated circuit and also includes a placeholder for additional logic circuits, wherein the placeholder includes connections to one or more input drivers of the pad ring and to one or more output drivers of the pad ring; and transmitting, storing, or displaying the integrated circuit design data structure.
