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.
