FreeLists / si-list / [SI-LIST] Re: Long trace open on the both ends

[Ravinder.Ajmani@xxxxxxxxxxxxxx]

Hi All,
I would like to thank all of you who responded to my query on the long 
trace open at both ends.  Broadly speaking, I received the following 
recommendations:

1) It should not cause any problem, so leave the trace as is.
2) Terminate the trace at both ends with its characteristic impedance.
3) Simulate it thoroughly to determine its impact.

I need to release the design in a couple of days, so I have decided to 
include in the design the pads for terminating resistors.  I will simulate 
it later and then decide whether to populate the resistors.
