Center Tapped Transformer Model Command on Cadence, Synopsys

[alex177]

I want to model a center tapped transformer and use it in my circuits. The spice netlist of my transformer is like this:

L1 in1 VDD 0.25u
L2 VDD in2 0.25u
L3 out1 out2 1u

The schematic is also attached. In LTSpice there is a command for mutual inductance definition. "K1 L1 L2 L3 0.99" However the command does not work on Cadence Virtuoso or Synopsys. How can I model and make it work on those simulators? Thanks.

Look for mind component in analogLib.

Thanks for return. Iam already using them. I am using 3 mind components. However can not see desired output unless if I do not attach one of inputs to gnd.

You need four inductances and two mutual inductances
LP1 in_p center_tap 0.25u
LP2 center_tap in_n 0.25u
LS1 out_p center_tap_s 0.25u
LS2 center_tap_s out_n 0.25u
K1 LP1 LS1 1
K2 LP2 LS2 1
