Abstract
A tracing method and apparatus for a digital emulation system. The invention allows trace information to be obtained during the emulation of a digital circuit that includes a clock signal. Input signal states are sensed and stored each clock cycle. The internal state of the emulated digital circuit is also stored. By using the stored input signal states and internal states, the states of other signals in the emulated digital circuit are derived.
