A system that can test individual components having tolerances on a circuit board without complete access to every node on the board is disclosed. The system uses a method that develops test limits from a model of the board, component tolerances, and a list of accessible nodes. A method of reducing the complexity of the test problem by limiting the number of components under consideration is also disclosed. A method of reducing the complexity of the test problem by limiting the number of nodes under consideration is also disclosed. A method of picking nodes to apply stimulus to a board is also disclosed. Finally, a method of correcting for certain parasitics associated with tester hardware is disclosed.
