Notes

1. For accurate results, the following conditions should be satisfied:
F[GHz] < 708/B[MILS], ER £ 50, and 0.01 £ W/B £ 100
where B is the ground-to-ground distance defined in the corresponding .SUB statement.

2. The transmission line is extended by a DL length, which is a function of the dielectric constant, frequency, and physical dimensions of the line. If the OPEN keyword is set to NEG, a nega­tive effect is applied. This holds true for the length extension DL, as well as the associated dielectric losses.

Netlist Form

SLOPEN:NAME n1 [ n2 ] W=val [OPEN=val] SUB=label

Netlist Example

SLOPEN:OPEN1 1 W=25MIL SUB=SUB1

or, negate open-end effect:

SLOPEN:OPEN2 1 W=25MIL OPEN=NEG SUB=SUB1

where SUB1 needs to be defined in the corresponding .SUB statement.
