Hi Kevin,

The netlist for transformer is included in the main . lib file - which is already encrypted. The only way to modify the turns ratio is to have the transformer

netlist un-encrypted and separated from the main encrypted model.

I can send you the encrypted netlist of the model (without transformer in it ) and the un-encrypted model of transformer. The customer then can modfiy the turns ratio and use both new netlists to run the sims.

Regards,

Arash
