I have been a board designer,

in accordance with my past experience, you should partition

your power system by your self. you can use tools

to help you debug, but we can't depend tools to help us

thinking.

Hi,
Some tools I know about, are:

1) Power Integrity from Cadence. It is actualy a part of SpecctraQuest product. The abilities are plane's resonanses investigation, impedance graphs considering capacitors placement, noise (SSN) influence and much more. The tool works in "frequency domain", i.e. you can not see the transient processes.

2) SpeedXP package from Sigrity. It worhs both in "frequency domain" and "time domain", thus you can see the animations of disturbance propagation across the plain, investigate SSN and noise influences etc.

There are, of course, many other tools doing the same job. Actually, you need to cooperate the tool with CAD system you use, because the tool contained in your single CAD package uses the same databases, graphical and models representations etc. Thus, if for example you are using Cadence Allegro or SpecctraQuest - of course, Power Integrity is the best option for you. Otherwise, you will have to enter the process of conversions, import/export problems etc.

Good luck, and I agree with previous post - the tool is only a tool, it means "garbage in - garbage out". But it is not a reason to reject using the tools, as you use calculator despite it can not think...
