Abstract: Various tools and techniques are provided for reducing an original circuit network into a simpler, realizable RCLM circuit network. Branches of the original network are merged to reduce its total number of nodes. More particularly, the branches of the original circuit are merged so that the resulting reduced circuit approximately replicates the timing characteristics of the original circuit over the desired operating frequency range. The determination whether to merge two branches is made based upon one or more circuit characteristics associated with the node connecting the branches.

Abstract: Various techniques and tools are disclosed for providing an osculating model of a circuit, which can be used to more accurately predict the circuit's operation. The parameters for a general model of the circuit are determined such that the general model matches desired circuit characteristics at one or more points. The parameters for the general model are determined such that the slopes of the general model at those points also match desired circuit characteristics. These determined parameters are used to create an osculating model specific to the circuit. The osculating model of the circuit can be employed to predict the operation of the circuit. Particular implementations of these techniques and tools may be used to predict the timing characteristics of a circuit having a capacitive, inductive, or magnetically-coupled load.
