Abstract
A system and method to determine a power-up parameter for a circuit board. The method includes electrically exciting a second-order circuit to generate an underdamped transient response. The method includes receiving, at a comparator coupled to the second-order circuit, the underdamped transient response. The method includes generating, in response to the underdamped transient response received at the comparator, a plurality of edges. The method includes receiving, at a single general purpose input/output pin of the electronic processor, the plurality of edges. The method includes determining a first response parameter based on a plurality of edges. The method includes determining a second response parameter based on the plurality of edges. The method includes determining the power-up parameter based on the first response parameter and the second response parameter.
