Rohan, 

Without knowing anything else about what you are reading it sounds like
they are referring to the capacitance and inductance.  If you were to
short the end of the line and measure you get the inductance, and if you
open the end of the line you get the capacitance.  These values can be
read from the smith chart at low frequencies by looking at the S11
measurement provided that the line is shorter than lambda/4.

Hi All, 

I was going thru Sigrity tutorial and there was a section on Open/Short
Circuit Impedance of the board. Can some1 explain in brief what that
means.
