ABSTRACT:
A method and apparatus for tracing any node in an emulator, including hidden nodes of a circuit design, includes maintaining a correspondence between physically observable nodes and hidden nodes of the circuit design being emulated. The correspondence identifies how values of the hidden nodes are to be determined based on corresponding ones of the physically observable nodes. The value of a hidden node is determined by obtaining the values of the corresponding physically observable nodes and identifying the value of the hidden node based on the correspondence between the corresponding physically observable nodes and the hidden node.
