naAccurate timing analysis has become increasingly important

due to the reduced timing margins of today’s high-speed

systems. The timing margins of a system define the maximum

frequencies that the system’s devices can run at for the system

to properly operate. Trace impedance, trace length, capacitive

device loading, jitter, and other such factors can affect these

margins and must be taken into account when performing the

timing analysis. This application note will describe the use of

IBIS models to calculate these factors to create an accurate

system timing model.
