Patent ID: 8046208

Claim:
A method for modeling a high speed interconnect and transmission line using closed form representations of the S-parameter comprising the steps: providing computer program instructions to a processor, the processor operable to execute the computer program instructions; constructing, by the processor executing the computer program instructions, a Discontinuity-Line Model which expresses the S-parameter in closed forms and allows for cascading the high speed interconnect; deriving, by the processor executing the computer program instructions, an equation for the S-Parameter of the Discontinuity-Line Model which takes into account a propagation constant for the transmission line; cascading, by the processor executing the computer program instructions, the Discontinuity-Line Model with at least another Discontinuity-Line Model to form a via-line-via model; and calculating, by the processor executing the computer program instructions, a cascaded S-parameter for the cascaded Discontinuity-Line Model.
