This application discloses a voltage analysis tool to perform a static power aware analysis on a circuit design without having to simulate the circuit design. The voltage analysis tool can determine a set of components in the circuit design corresponds to a design pattern representing a voltage-transition device, and set an output voltage for the set of components based, at least in part, on characteristics of the voltage-transition device. The voltage analysis tool can propagate the output voltage to other portions of the circuit design, and determine whether the portions of the circuit design receiving the output voltage have a rule violation.
