Title: LTspice schematics must go into another tool for generating board layout
Post by: abdulbadii on September 28, 2021, 11:20:04 pm
What would be convenient way importing LTspice schematics into some tools on Linux for generating board layout, in definitive clear step by step

pcb and Kicad  is readily installed

Please any experienced one share and show us

Step by step: select parts that match your simulation's components and put them in to KiCad's schematic editor. LTspice deals with idealized passives and models; for prototyping you need to pick real components that are linked to a BOM and a footprint, which LTspice knows nothing about.

Edit to add: if you want to try new and bleeding edge, there are tools like https://www.flux.ai (https://www.flux.ai) that aim to integrate simulation, ECAD, MCAD, and firmware development. It's being developed by a friend of a friend of mine. Current tools don't lend themselves to turning a simulation into a schematic without basically redrawing it; some EDA packages have internal SPICE engines, but seemingly nobody uses them.

You can also try that, but haven't tested it: https://github.com/laurentc2/LTspice2Kicad

I personally do not really recommend using LTSpice as a schematics editor for anything else than simulation purposes, as it's pretty rough, but that's your call.

Web based <anything>. No thanks. I understand why but just no

Kicad has a built in simulator. Don't know much about it but it's been there for a while.
Altium's simulator didn't look half bad.

The flux ai is an intriguing project. But browser based ... yuk. Come on, something that is as performance intensive as a pcb editor needs to be native. Also this stuff is cloud dependent...
