Looking for a tool to get smith chart of a differential circuit

I have a differential transformer (4 ports) and RLC circuits, and I need to get the smith chart using these circuitry.
Which tool can i use for this purpose? where can i find an example?
Thank you!

There is a software tool called 'RFsim'. It can be used to obtain frequency parameters and for rf analysis. Google the term to get link.

What do you exactly want to do ?
