Systems and methods are disclosed for integrated circuit design using integrated circuit shells. For example, a system may generate an integrated circuit core design expressed in a hardware description language. The integrated circuit core design may express circuitry that describes one or more functions to be included in an application specific integrated circuit (ASIC). The one or more functions may have connection points providing first inputs and outputs to the one or more functions. The system may query an integrated circuit shell expressed in a hardware description language. The integrated circuit shell may express circuitry that describes a limited set of pads to be implemented in the ASIC. The limited set of pads may provide second inputs and outputs to the integrated circuit. The query may determine availability of pads of the limited set of pads to connect to the connection points of the one or more functions.
