* Subcircuit test
|
|
* test is a subcircuit that models a 2-conductor transmission line with
|
|
* the following parameters: l=9.13e-09, c=2.75e-13, r=0.2, g=0,
|
|
* inductive_coeff_of_coupling k=0.36144, inter-line capacitance cm=9e-14,
|
|
* length=24. Derived parameters are: lm=3.29995e-09, ctot=3.65e-13.
|
|
*
|
|
* It is important to note that the model is a simplified one - the
|
|
* following assumptions are made: 1. The self-inductance l, the
|
|
* self-capacitance ctot (note: not c), the series resistance r and the
|
|
* parallel capacitance g are the same for all lines, and 2. Each line
|
|
* is coupled only to the two lines adjacent to it, with the same
|
|
* coupling parameters cm and lm. The first assumption implies that edge
|
|
* effects have to be neglected. The utility of these assumptions is
|
|
* that they make the sL+R and sC+G matrices symmetric, tridiagonal and
|
|
* Toeplitz, with useful consequences (see "Efficient Transient
|
|
* Simulation of Lossy Interconnect", by J.S. Roychowdhury and
|
|
* D.O Pederson, Proc. DAC 91).
|
|
|
|
* It may be noted that a symmetric two-conductor line is
|
|
* represented accurately by this model.
