Tim, In SPICE each kind of element has a specific letter. R is a resistor, C is a capacitor, etc. When Avant! implemented the coupled lossy line model in HSPICE, they chose to use the letter W to indicate the coupled lossy line element. Most of the other letters were already used to specify other types of elements. This always reminds of the day that I found out that ski-doo was a brand of snowmobile and not a type of vehicle :) In Portugal, few people use the word for vacuum cleaner. It's just a "Hoover".

I have been using W-element model from long time, but never known what the "W" stands for? Can anyone explain to me why multi-xline model is called W-element? Where is the term extract from?
