CLINP simulates a pair of symmetric coupled lossy transmission lines that support non-TEM modes of propagation (odd and even). Each mode is specified by its effective dielectric constant and per-unit-length attenuation. By default, CLINP provides partial account for circuit loss. You can toggle the secondary parameter Total_Loss to access insertion loss, return loss, and dielectric loss, as well as loss scaling at a user-specified frequency.

ZE, ZO, KE, KO. Even and odd characteristic parameters used to obtain entries of line Y-matrix.
AE, AO, F0. Frequency for scaling (imparting the frequency-dependence to the attenuation constant AE and AO). If F0 is not equal to zero (0.0), then
freq is the evaluation frequency,
and Loss is attenuations AE and/or AO. If F0 is equal to zero, the attenuation is
constant versus frequency and is equal to parameter AE and/or AO(dB/m). Note that loss
scaling is available only if the control parameter Total_Loss=Full.
LossModel is a secondary control parameter that defines how the model accounts for loss and dielectric parameters. If LossModel=Partial (default value) then the model accounts for insertion loss (parameter Loss) only. If LossModel=Full then the model accounts for insertion loss, return loss, dielectric loss, and for frequency-dependent model of dielectric parameters (for example, for microstrips, stripline, or other).
NOTE: The secondary parameter LossModel displays when you click the Show or hide secondary parameters button on the toolbar of the the Element Options dialog box Parameters tab. If LossModel=Full, additional secondary parameters display.
EpsFreqDep is a (secondary) control parameter that defines if dielectric constant and dielectric loss tangent exhibit the predefined frequency dependence, suggested in . This dependence is controlled by the three frequency parameters Fmin, Fmax, and Fspec, and imparts causal behavior to the model.
This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
CLINP is a behavioral model that allows you to enter six electric parameters of your
choice (unlike models such as MCLIN where you enter primary geometrical/material
parameters). The set of parameters may not be feasible or even totally non-physical, and
this may affect transient simulation. In the event of a transient simulation failure,
Cadence® BSIM4 recommends checking error/warning messages in the HSPICE output file
AwrHSpice.lis and modifying parameter values accordingly.
