4.23. MOSFET
RLC
Transmission line with series loss only
RC
Uniform RC line
LC
Lossless line
RG
Distributed series resistance and parallel conductance
All other combinations will lead to an error.
REL and ABS are model parameters that control the setting of breakpoints. A breakpoint is
a point in time when an analysis is unconditionally performed. The more there are the more
accurate the result but the longer it will take to arrive. Reducing REL and/or ABS will yield
greater precision.

Example
The above could represent a 10 metre length of RG58 cable. The parameters would be described
in a .model statement e.g.
.model RG58_10m LTRA(R=0.1 C=100p L=250n LEN=10)
