Download a blank design to ensure that: (1) no input noise is captured; and (2) all internal logic and configuration circuits are in a known state.

Note: A blank design is a design with a single gate or flip-flop that never toggles, and in which all outputs are in a 3-state configuration.

Wait for the junction temperature to stabilize, then measure VCCINT, VCCAUX, and any other supply source of interest. With special equipment, a simple heat gun, or cold spray, you can force temperature changes to evaluate the influence of the environment on the device static power. VCCADC should always be connected to VCCAUX.
