MixedSignal layout issue

Hi everyone

We are just starting the SOC design project which includes large digital logics &
PMU(DC-DC converter) & Audio CODEC (or D-Class AMP)

We are concerned about noise/interference/EMI issues when all these block are integrated in single chip.
(especially about grounding, shielding, de-coupling, etc)

is there any materials(book/document/paper or advices, etc) that help us?

thanks in advance

Go to analogue dialog website. They have some very good papers on grounding shielding etc.
Just reply If u want me to post some of those papers.

regards

contains some papers from analog dialogue. gives basic understanding

Avoid the stupid error to simulate a power supply net somewhere in the middle of the project!

There are sucessful SOC matching your components. But start before doing any scheduling and circuit partioning of a supply analysis.

Model the board components, the package, the internal decoupling, the internal impedance, the internal noise sources, the receivers, the interface between quiet and noisy, substrate separation and connections, ...

This simulation formation provide you enough guidelines for the SOC project.
