How to run paranoia_parallel
|
||||||
|
|
||||||
|
Install valgrind
|
||||||
|
Install parallel
|
||||||
|
|
||||||
|
Extract paranoia_parallel.7z into a directory of your choice.
|
||||||
|
In a terminal window, cd into the directory chosen.
|
||||||
|
|
||||||
|
Edit runtest.sh, line 14, -jx, with x being the physical cores available on your machine.
|
||||||
|
|
||||||
|
Run ./paranoia_table_generators.sh
|
||||||
|
to generate some input tables (only required once in the beginning).
|

This directory holds a SPICE netlist with SPICE2 POLY constructs in
|
||||||
|
controlled sources as typically found in vendor models. The circuit
|
||||||
|
is just a two-stage transimpedance amp using an AD8009,
|
||||||
|
along with some slow components (AD780 and OP177A) to set bias
|
||||||
|
points. Vendor models are used for all active components.
|
||||||
|
Successfully running this test shows that you have successfully built
|
||||||
|
the XSpice stuff with the POLY codemodel, and that you should be able
|
||||||
|
to simulate SPICE netlists with embedded vendor models.
|
||||||
|
|
||||||
|
To run this netlist, just do the following:
|
||||||
|
|
||||||
|
[localhost]# ngspice
|
||||||
|
ngspice 1 -> source output.net
|
||||||
|
ngspice 2 -> run
|
||||||
|
ngspice 3 -> plot Vout2
|
||||||
|
|
||||||
|
(Note that when you read in the netlist, you will get a bunch of
|
||||||
|
warnings saying stuff like:
|
||||||
|
|
||||||
|
Warning -- Level not specified on line "()"
|
||||||
|
Using level 1.
|
||||||
|
|
||||||
|
Also, ngspice will complain about:
|
||||||
|
|
||||||
|
Error on line 50 : r:u101:1 u101:40 0 1e3 tc=7e-6
|
||||||
|
unknown parameter (tc)
|
||||||
|
Error on line 283 : .temp 0 25 50 75 100
|
||||||
|
Warning: .TEMP card obsolete - use .options TEMP and TNOM
|
||||||
|
|
||||||
|
You can ignore all this stuff . . . .)
|
||||||
|
|
||||||
|
You should get a pop-up window showing two square pulses (the second
|
||||||
|
smaller than the first) with a little bit of overshoot on the rising
|
||||||
|
and falling edges.
|
||||||
|
|
||||||
|
This stuff was done as an adjunct to work on the gEDA project.
|
||||||
|
Information about gEDA is available at http://geda.seul.org/ .

* 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.

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
|
||||||
|
* 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.

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:
|
||||||
|
* L = 9.13nH per inch
|
||||||
|
* C = 3.65pF per inch
|
||||||
|
* R = 0.2 ohms per inch

|
* 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
|

|
* Several simulations are performed by this file.
|
||||||
|
* They are:
|
||||||
|
* 1. An operating point at 0.7v forward bias.
|
||||||
|
* 2. An ac analysis at 0.7v forward bias.
|
||||||
|
* 3. The forward and reverse bias characteristics from -3v to 2v.
