WOW! Spice and your Spice models. THANK YOU!

Now all I have to do is learn to use Spice and learn to write Spice models for drivers.

Writing nodal circuits is not a problem. I have to do that with my version of CALSOD anyway. CALSOD can accept measured FR, IMP and Phase data directly. And if you do not have Phase data, it will recreate it. I am not sure how Spice deals with measured results. But I will check it out.

Thanks again.
