Patent ID: 7079997

Claim:
Computer readable media containing program instructions for causing a computer to carry out a process comprising the steps of: a. generating a display including a first statement event symbol representing a first statement event in which a simulator carrying out a first simulation of a circuit determined a value of a first signal of the circuit at a first simulation time, wherein the first statement event symbol references the first signal, indicates the value of the first signal at the first simulation time, and resides in the display at a position associated with the first simulation time, and b. for each second signal of the circuit having a value at a second simulation time that is a function of the value of the first signal at the first simulation time, responding to user input requesting a fan-out display relative to the first statement event symbol by adding a second statement event symbol to the display representing a statement event in which the simulator determined a value of the second signal at the second simulation time, wherein the second event symbol resides in the display at a position associated with the second simulation time.
