Transmission Line, Physical Length with Reference


 

Netlist Format

An instance of a transmission line with physical length and reference nodes has the following netlist syntax:

Axxx n1 n2 n3 n4 [W=val] [P=val]
COMPONENT=TRL SUBSTRATE=substrate_name

n1, n2, n3, and n4 are the names of the nodes attached to the transmission line. The entry COMPONENT=TRL identifies the element as a transmission line with physical length.

The SUBSTRATE=substrate_name is the offset stripline substrate model name selected for the design (see Selecting an Offset Stripline Substrate for details.

Parameter

Description

Units

Default

P

Physical length

Meter

1e-2

W

Conductor width

Meter

1e-3

Netlist Example

A5 Port1 Port2 0 0 W=0.001 P=0.01 COMPONENT=TRL SUBSTRATE=OSL1

where OSL1, the selected layout technology or substrate type, has a definition such as:

.SUB OSL1 OSL(
+ B=0.001524 Er=4.4 TAND=0.02 BL=2.5400e-004
+ MET1=1.724137931034483 T1=2.5400e-005
+ RGH=0)

Notes

1. [Stripline] For accurate results, the substrate definition should specify W/B <10.
