Method and apparatus for determining nets among nodes in a circuit board

Image Number 4 for United States Patent #5187430.

Method and apparatus for determining nets among nodes in a circuit board that includes applying a potential to a reference conducting surface oriented with respect to the board; measuring a parameter of an electrical response at a node of interest; and comparing the measurements to determine a plurality of nets among the nodes. The tentative net list developed from the measured parameters is then verified using continuity testing.
