1. In an emulation system, a method for tracing hidden nodes of a circuit design, the method comprising the steps of:

  • (a) maintaining a correspondence between a plurality of physically observable nodes of the circuit design and the hidden nodes, including how values of the hidden nodes are to be determined based on the plurality of physically observable nodes;

    (b) accessing values of the plurality of physically observable nodes; and

    (c) determining the values of the hidden nodes based at least in part on both the values of one or more of the plurality of physically observable nodes and the correspondence between the plurality of physically observable nodes and the hidden nodes.
