How to set up GTL Ref Values for 45nm & 65nm

[seban]

Also to make things more precise "cross" exchanging correction numbers to "-" values like example below does not lead to same GTL resolute. They are completely different values which give completely different GTLs.

GTL Ref 0 = +50mv = GTL = 0.9336025v
GTL Ref 1 = +10mv = GTL = 0.9381305v
GTL Ref 2 = +50mv
GTL Ref 3 = +10mv

not equal

GTL Ref 0 = +30mv = GTL = 0.9136025v
GTL Ref 1 = -10mv = GTL = 0.9181305v
GTL Ref 2 = +30mv
GTL Ref 3 = -10mv

Above calculations made for vtt = 1.365v
