Title: distributed interconnect paramter calculation in cadence

I wanted to know how to define distributed transmission line parameter in cadence ? can it be done with mt line ?

why don't u just use the transmission line equivalent models i.e L R and C if you have them?

sujeetkumarmehta,

if you have a single line use the tline in the analog lib. There are more entries in the form than needed to make the model work. Typically I just enter characteristic impedance and length. The same applies to the mtline.

consider the possiblitity of lumped elements in a cascaded chain. Frequently this is more accurate than doing the transmission line model.
