Multi-Coupled Lines, Differential Pairs, Field Solver

 

 

Netlist Form

A multicoupled line, two differential pairs, field solver instance has the following netlist syntax:

Wxxx n1 n2 n3 n4 0 n5 n6 n7 n8 0 N=4 L=length FSmodel=modelname

.MATERIAL cond1 METAL CONDUCTIVITY=conductivity
.MATERIAL diel1 DIELECTRIC ER=er LOSSTANGENT=losstangent
.SHAPE rect1 RECTANGLE WIDTH=w HEIGHT=t1 // Conductors
.LAYERSTACK STACK1
+ LAYER=(cond1, t2) // Ground plane
+ LAYER=(diel1, h)
+ LAYER=(AIR, hu)
.MODEL modelname W MODELTYPE=Fieldsolver
+ LAYERSTACK=STACK1
+ CONDUCTOR=(SHAPE=rect1, ORIGIN=(0, 't2 + h')
+ MATERIAL=cond1, TYPE=SIGNAL)
+ CONDUCTOR=(SHAPE=rect1, ORIGIN=('w+gap', 't2 + h'
+ MATERIAL=cond1, TYPE=REFERENCE)
+ CONDUCTOR=(SHAPE=rect1, ORIGIN=('2w+gap', 't2 + h')
+ MATERIAL=cond1, TYPE=SIGNAL)
+ CONDUCTOR=(SHAPE=rect1, ORIGIN=('3w+2gap+sep', 't2 + h')
+ MATERIAL=cond1, TYPE=REFERENCE)

n1, n2, n3, and n4 are the names of the input nodes. n5, n6, n7, and n8 are the corresponding output nodes. The entry N=4 shows that this is a 4-conductor, 2-pair differential line.

The entry FSmodel=modelname identifies the field solver microstrip model.
