Hi all,
I am trying to create a distributed model for an inductor in Cadence using one "ind" element from analogLib as one loop of my actual inductor and repeating the single distributed cell N times where N is the total number of turns. I can couple two of the loops using "mind" component from analogLib. However, I want to couple all of these inductors (260 loops in total) to each other. I cannot get away with using "mind" component to couple each inductor to its neighbour. I would have to couple each one to every other one so I would need to have 260C2 (= ~33000) "mind" components.
In LTSpice, one is able to use K-statements to couple multiple inductors together in a single statement:
K1 L1 L2 L3 L4 1
The same trick does not work if I modify my netlist in Cadence to include:
K0 mutual_inductor coupling=K ind1=L0 ind2=L1 ind3=L2 ind4=L3
Is there a way to couple all of these "ind" elements together or in other ways couple all these windings to the same core? I am not sure of how to use the "winding" and "core" components because I do not have a model for the core. Alternatively, is it possible to view the source code for this "mind" component so I could modify it to work for multiple inductors?
Regards,
Preet
