Abstract
With the development of micro-electronics technology and computer technology
锛?/p>
application of signal integrity analysis is the only way to solve high-speed system
design. By dint of SpecctraQuest which is a powerful simulation software, it
鈥?/p>
s a
simple and doable analytical method to make use of IBIS model to analyze signal
integrity on high-speed signal lines before component placement and routing. This
method can find out signal integrity problem and make optimization design on
interrelated problem of signal integrity. Then the design period is shortened.
In this paper
锛?/p>
interrelated problem of signal integrity, PCB design based on signal
integrity, transmission lines basal principle are introduced summarily
锛?/p>
The interrelated
problem of reflection and crosstalk which are the two important factors that influence
signal integrity is expounded. It gives effective methods to reduce reflection and
crosstalk. The establishment of emulational model based on SpecctraQucst is
discussed and the result of simulation is analysed. The researchful fruit indicates it
鈥?/p>
s
doable and necessary to adopt emulational design based on signal integrity in
high-speed electrocircuit design.
