Coupled Coplanar Lines

C_NCOUP (N=1,2,3,...,10) represents N multiple coupled coplanar lines. The geometrical dimensions of the coupled lines are defined using the data item addressed by C_NL_TYP. L is the length of the coupled section. The substrate data are defined in data item addressed by C_SUB.

Parameters

Parameter	Description
L	Line length (stretchable)
C_NL_TYP	IID of data items with the geometrical dimensions of coupled coplanar lines
C_SUB	ID of coplanar substrate definition
C_GRID	ID of simulation control data
TEMP	ID of element temperature definition used for noise computation

Notes

A zero or negative value for L can be meaningful during the simulation. In such cases, the automatic layout generation works incorrectly and the generated layout has to be edited manually. The minimum value for L depends on the metal layer oversize in the currently selected foundry. In case of DEFAULT foundry, L should be greater than or equal to max(|cond_os|, |cond2_os|).
C_LTYP is the ID of the line type data item in which the geometrical dimensions of the line are defined.
If L1 in selected C_GRID is not set to –1 or –2 (auto sizing), the minimum value for L1 depends on the nmber of coupled lines N and has to be:

L1_min=W1+W2+ ...+2(S1_2 + S2_3 + ...)+SG1+SG2+2GW
