Signal Integrity Analysis Chapter I. Summary

• Space

5, in order to detect, correct and prevent signal integrity problems, the physical design must be converted into an equivalent circuit model and this model to simulate the waveform, in order to produce the product before the prediction performance.

6, the use of three levels of analysis accumulated electrical effect-the rule of thumb, the analysis of myopia and numerical simulation tools, which can be applied to modeling and simulation.

7, the measurement of passive devices and interconnect electrical performance of the instrument generally have three kinds: Impedance analyzer, network analyzer and time-frequency reflector.

8. These instruments play an important role in reducing the reliability of design risks and improving the accuracy of modeling and simulation processes.

9. Understanding the four signal integrity problems can be the most important way to eliminate these problems. The general solutions to these four signal integrity problems are summarized.

Design principle of noise type

Signal quality signals should feel the same impedance over the entire interconnect (impedance matching and signal line width are uniform)

Crosstalk keeps the spacing between lines greater than the minimum and minimizes mutual inductance between lines and non-ideal return paths

Track collapse minimizes the impedance and noise of the power/ground path

Electromagnetic interference minimizes bandwidth and ground impedance and takes shielding measures
