* 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 |

* 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. |

* 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 |
|||
* + 30% = 46.8e-12 F/m = 0.468pF/cm |
|||
* |
|||
* 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 |
|||
* = 12.45ohms/cm |
|||
* |
|||
* transmission line parameters: |

* nominal z0 = sqrt(L/C) = 137 ohms |

* td = sqrt(LC) = 64.14e-12 secs/cm = 0.064ns/cm |

* 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 |

* + 30% = 46.8e-12 F/m = 0.468pF/cm |
|||
* |
|||
* 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 |

* = 12.45ohms/cm |

* |

* transmission line parameters: |

* 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. |
