Anyone had any meaningful results when trying to run SI on long traces. Im
attempting
to characterise some of our boards and chips to check Protel against the real
thing.

I can load in the ibis model of the chip OK. I am running  the board using a 250
MHz
square wave and 100 mm unterminated trace length between the IC and an SMB
socket.

But Im getting a nice looking square wave with no ringing. A funny thing is that
SI thinks the connector is an IC even though it is defined as a connector.
