+* Subcircuit conv2wtwentyinch
+* conv2wtwentyinch is a subcircuit that models a 2-conductor transmission line with
+* the following parameters: l=9.13e-09, c=3.65e-12, r=0.2, g=0,
+* inductive_coeff_of_coupling k=0.482, inter-line capacitance cm=1.8e-12,
+* length=20. Derived parameters are: lm=4.40066e-09, ctot=5.45e-12.
+*
+* 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 imply 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.
+*
+* It may be noted that a symmetric two-conductor line will be
+* accurately represented by this model.

+* Subcircuit test
+* test is a subcircuit that models a 4-conductor transmission line with
+* the following parameters: l=9e-09, c=2.9e-13, r=0.3, g=0,
+* inductive_coeff_of_coupling k=0.6, inter-line capacitance cm=3e-14,
+* length=6.3. Derived parameters are: lm=5.4e-09, ctot=3.5e-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.

+* 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.

+ BJTdriver -- 24inch lossy line LTRA model -- DiodeCircuit
+
+* This unclassified circuit is from Raytheon, courtesy Gerry Marino.
+* It consists of a BJT driver connected by a 24 inch lossy line to a
+* passive load consisting mostly of diodes. Each inch
+* of the lossy line is modelled by 10 LRC lumps in the Raytheon
+* model.
+
+* The line parameters (derived from the Raytheon input file) are:
+* L = 9.13nH per inch
+* C = 3.65pF per inch
+* R = 0.2 ohms per inch

+* Subcircuit conv2wtwentyinch
+* conv2wtwentyinch is a subcircuit that models a 2-conductor transmission line with
+* the following parameters: l=9.13e-09, c=3.65e-12, r=0.2, g=0,
+* inductive_coeff_of_coupling k=0.482, inter-line capacitance cm=1.8e-12,
+* length=20. Derived parameters are: lm=4.40066e-09, ctot=5.45e-12.
+*
+* 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 imply 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

+* Subcircuit test
+* test is a subcircuit that models a 4-conductor transmission line with
+* the following parameters: l=9e-09, c=2.9e-13, r=0.3, g=0,
+* inductive_coeff_of_coupling k=0.6, inter-line capacitance cm=3e-14,
+* length=6.3. Derived parameters are: lm=5.4e-09, ctot=3.5e-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.

+ BJTdriver -- 24inch lossy line TXL model -- DiodeCircuit
+
+* This unclassified circuit is from Raytheon, courtesy Gerry Marino.
+* It consists of a BJT driver connected by a 24 inch lossy line to a
+* passive load consisting mostly of diodes. Each inch
+* of the lossy line is modelled by 10 LRC lumps in the Raytheon
+* model.
+
+* The line parameters (derived from the Raytheon input file) are:
