Free options for signal integrity (like HyperLynx)?

[Evan_Shultz]

Hi all!

For determining signal integrity of a board before manufacture, I know about HyperLynx and Sigrity. Are there any other options? Ideal would be a free and open source alternative, such as KiCad is to Altium and Allegro. Thanks for any tips!

I think @pointhi has been doing some research in this area

Have you looked at Openems?

Export PCB board to OpenEMS?

Hello all, Recently I’ve discovered OpenEMS and I would like to use it to simulate some RF board that I’ve created using Kicad. But seems that there are a big hole between those tools. Perhaps the way to go would be to create a python script that reads the .kicad_pcb file and generates a octave/mathlab .m file for OpenEMS ? Anyone had some experience doing that ? thanks

Thanks Jon!

@Shack Thanks for suggesting this. I found this post already and I perhaps I misunderstand the capabilities of OpenEMS, but I’m looking for a signal integrity tool and I don’t see OpenEMS can do that. There is some overlap in capabilities between the products, but I don’t see that OpenEMS can do this stuff: https://eda.sw.siemens.com/en-US/pcb/hyperlynx/signal-integrity/.
