EMI simulation

[barismetin]

Hi everyone, I have PCB design in Altium. I would like to do some EMI simulation on my design. What is the best way to do it? I am open to any recommendation. Thank you.

I am also curious to see any suggestions? Maybe what software, how to start, what to focus on .... interesting topic.

But I believe it is not so simple and it may be just easier faster and cheaper to go to a test house. Of course, depends on what is on the board.

Yeah true Robert, I agree it is really hard to simulate all scenarios but so far CST is the best software I found

[anovickis]

I'm assuming you want to simulate some high speed channels for loss/impedance match, or are you looking for RF fields from clocks or other ?

I am trying to simulate EMC on PCB, I would like to measure far-field radiation from PCB using simulation software

Bring a wheelbarrow of gold, then when you get the empty wheelbarrow back, send a second one for the computer farm you will need


And some open source

​Very nice list! Thank you anovickis

I need to reproduce EMI Effect on one topology.(DDR SDRAM or SDRAM geography : 8 - 16 information signals, clock signal, adress\control signals) Is it conceivable these signs I mimic one time and I see EMI estimations load up level? I utilize Allegro PCB SI. I know Allegro PCB SI figure single net EMI reenactment?

I do not really have experience with EMI simulation ... at lest not yet. The best may be to speak to someone in Cadence to help you with this - or maybe someone from this forum can help?
