1. A method for measuring a quiescent current in a switching voltage regulator, the method comprising:
generating a mathematical model of a circuit design associated with the switching voltage regulator, the mathematical model comprising measurable parameters to describe a switching current associated with a power switch of the switching voltage regulator;
fabricating a circuit comprising the switching voltage regulator based on the circuit design, the fabricated circuit comprising the power switch and conductive inputs/outputs (I/O);
coupling the conductive I/O of the fabricated circuit to a circuit test fixture;
providing electrical signals to the conductive I/O via the circuit test fixture;
measuring the measurable parameters in response to the electrical signals;
applying the measurable parameters to the mathematical model to calculate the switching current; and
calculating the quiescent current based on the switching current.
