Abstract
A method of provisioning an integrated circuit with decoupling capacitance includes identifying in an initial design of the integrated circuit lacking decoupling elements, a standard cell instance satisfying a transient power or frequency switching criteria. Based on a transient power characteristic of the standard cell instance, a decoupling capacitance requirement for the standard cell instance is determined. The decoupling capacitance requirement indicates a capacitance sufficient to bring the standard cell instance into compliance with a stability constraint on a supply voltage node of the standard cell instance. A decoupling capacitor satisfying the decoupling capacitance requirement is provisioned by appending an appropriate sized decap transistor having one or more gate electrode elements to the standard cell instance. The size of the decap transistor may be derived from the required decoupling capacitance, the amount of decoupling capacitance contributed by each gate electrode element, and the area required for each gate electrode element.
