The 2-D transmission line parameters can be calculated in both
TEM and PEEC depends on how you want to select. During the analysis
mode it will ask you whether you want to compute the conductors losses.
If you do not want to compute conductor losses, it will use the default
TEM mode. If you want to compute conductor losses, then it will use the
PEEC approaches for inductance and I believe the capacitance is still
based on boundary elements. The manual does not organizes well and it
is very confused.

no it doesn't. it only says the 2d transmission line parameters
are calculated in tem mode.
