Hi Joshmachine,

 The switch delay is introduced because of the transmission line delay.=20
 If the clock and data lines are well matched, this parameter can be=20
 Ignored or will not have any effect on the Setup and hold time
violation.
=20
 The Settle delay is the skew which should be included in the setup and
hold=20
 time calculation. (Because of under and over shoot the signal will not
be  =20
 Settled to defined logic)

 The settle delay is the time taken by the signal to settle into the
high  =20
 State logic or low state logic of the receiver.

Please Correct if I am wrong.

Thanks
Dharmendra.G  =20
