|
||||
* 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.

* From neug1, Mosaic aluminum lines. 2um thick, 11um wide. Assuming

* 10um above the ground.
|

* Material: aluminum; resistivity (sigma) = 2.74uohm-cm = 2.74e-8 ohm-m
|

* Dielectric: SiO2, dielectric constant (epsilon) =3.7
|

* epsilon0 = 8.85e-12 MKS units
|

* mu0 = 4e-7*PI
|
||||
* speed of light in free space = 1/sqrt(mu0*epsilon0) = 2.9986e8 MKS units
|

*
|

* Line parameter calculations:
|

* capacitance: parallel plate
|

* C = epsilon*epsilon0 * A / l
|

* C = 3.7*8.85e-12 * 11e-6 * 1(metre) / 10e-6 = 36.02e-12 F/m
|

|

*
|

* C_freespace = 46.8e-12/epsilon = 12.65e-12 F/m
|
||||
* speed of light in free space v0 = 2.9986e8 = 1/sqrt(L0*C0)
|
||||
* => L0 = 1/C0*v0^2
|
||||
* L0 = 1/(12.65e-12 * 8.9916e16) = 1/113.74e4 = 0.008792e-4 H/m
|

* = 0.8792 uH/m = 8.792nH/cm
|

*
|

* R = rho * l / A = 2.74e-8 * 1 / (11e-6*2e-6) = 1245.45 ohms/m
|

|

* transmission line parameters:

* From neug1, Mosaic aluminum lines. 2um thick, 11um wide. Assuming

* 10um above the ground.
|

* Material: aluminum; resistivity (sigma) = 2.74uohm-cm = 2.74e-8 ohm-m
|

* Dielectric: SiO2, dielectric constant (epsilon) =3.7
|

* epsilon0 = 8.85e-12 MKS units
|

* mu0 = 4e-7*PI
|

* speed of light in free space = 1/sqrt(mu0*epsilon0) = 2.9986e8 MKS units

*
|

* Line parameter calculations:

* capacitance: parallel plate
|

* C = epsilon*epsilon0 * A / l
|

* C = 3.7*8.85e-12 * 11e-6 * 1(metre) / 10e-6 = 36.02e-12 F/m

|

*
|

* C_freespace = 46.8e-12/epsilon = 12.65e-12 F/m
|
||||
* speed of light in free space v0 = 2.9986e8 = 1/sqrt(L0*C0)
|
||||
* => L0 = 1/C0*v0^2
|
||||
* L0 = 1/(12.65e-12 * 8.9916e16) = 1/113.74e4 = 0.008792e-4 H/m

* R = rho * l / A = 2.74e-8 * 1 / (11e-6*2e-6) = 1245.45 ohms/m

* 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 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.
