1. A method for providing more information to the digital simulation results database, either from the simulator or directly from the description of the circuit being simulated, resulting in a more compact representation of the database and a more efficient processing of the data stored in it, the method comprising the steps of:

  • (a) declare to the database which of the signals are basic signals, whose changes in values must be stored as they are reported by the simulator. (b) declare to the database which signals are auto-generate signals and what is the way to generate all their changes in value without needing information from any other signal. (c) declare to the database which signals are derived from other signals and the way to generate all their changes in value without needing information from any other signal except of those referenced in the declaration. (d) report to the database transactions, each transaction consisting of (1) signal identifier, (2) signal value (including strengths information if necessary), (3) time at which the change occurred, and optionally (4) delta count as partial order information, where signal identifier must be identifying a basic signal.
