Is there any free em simulation software for pcb?

I want to see how my signals are travelling in pcb.

I'm not much aware of the Free EM Simulation tool. Maybe some other help you.
But Look out for Robert's youtube videos. He has many videos on this : https://www.youtube.com/channel/UCJQ...A8bgDmPlJlOJOA

We are talking about simulation tools here, it may help: https://designhelp.fedevel.com/forum...-analysis-tool

PS: I have not worked with free simulation tools, so I am not sure about them

Recently, in signal integrity journal, they had an article about low cost and free tools. Maybe this will be of interest if it doesn't completely answer your question.
