Abstract
Embodiments of a computer system for simulating a circuit are described. During a first mode of the simulation, the computer system stores primary signals and circuit relationships between primary signals and secondary signals associated with a portion of the circuit in a file, where the primary signals are independent of gate outputs in the portion of the circuit, and the secondary signals are driven by gates in the portion of the circuit. Moreover, during a second mode of the simulation, the computer system stores dynamic changes in additional relationships between signals to the file, where the signals can include primary signals, secondary signals, or both.
