Is there any software to convert SPICE Models to a schematics?
In other terms, I am looking for an alternatif of SpiceVision PRO
I am only aware of two alternatives to the commercial software you linked in your question. There could be others, and if anyone comments with more suggestions I can edit the answer.
I have little to no experience using either of the above. I've manually "decompiled" netlist to LTspice schematic a couple times, but it's very tedious and only useful for learning the process or honing your skillz with SPICE syntax. Therefore, I generally don't recommend the manual process unless the netlist is only a few lines.
