Method for propagating switching activity information in digital combinatorial networks |
摘要 |
A method is provided for computing signal and switching probabilities at an output of a logic circuit in a network having multiple logic circuits. The method for computing the signal and switching probabilities includes steps of creating a truth table for a logic circuit where the truth table has entries respectively corresponding to signals at inputs of the logic circuit, choosing in sequence one of entries each representing switching of a signal at the output of the circuit, determining whether a signal at an input corresponding to the chosen entry is at logic high, assigning an event probability representing that the signal is at logic high, and accumulating event probabilities respectively assigned to signals at inputs corresponding to the chosen entries to produce the signal probability at the output of the circuit.
