Thanks for your replies in the first.
I think the SI is a full design flow work.I built a SI group just two years ago in our company.There is over 10,000 hardware engineers.We don't have so much money to provide the SI analysis environment for every engineers including the hardware and software platforms.But everybody should have some skills in SI including some thumb rules.The layout engineers should finish the post-layout SI analysis and EMC/EMI DRC.
SI engineers should have a system design concept.They should put out a solution by considering every factors and finish the most difficult SI analysis.In the same time,they should have a good balance between the performance and the cost.This is my goal.
But by now,We don't have the system engineering design ability.Most of our SI engineers have less practices and can't do a good system margin plan(some things can't be simulated and only analysis by your practice datas).They are familiar with some SI analysis tools and some a basic understanding of transmission lines theory and timing.They can finish the net topology analysis and finish the I/O Buffer choose and the terminal plan and the stack-up etc.In a word, it is just a good start. I want to build a really SI group and a good SI engineer.I think the good corporation is the first things in different engineers.Can you tell me how to distribute the SI works in the different engineers?What's their duties?Waiting for your suggestions.

Regards,

Rachild
