Implements an ideal transformer with primary coil between nodes 1 and 2 and secondary coil between nodes 3 and 4. The ratio of secondary to primary turns is given by N. "Ideal" means that DC is also transformed with this element. If you do not want to transform DC, you need to add capacitors on either side of the model to block DC.
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.
