The article and the program are in German, from 1985: https://www.64er-magazin.de/8508/netzwerk.html
I tried it out for shits and giggles, and it works. And it's even absolutely useable fast, though I've only tried analyzing a small common base amplifier circuit. Not bad at all for something that you can type in as a BASIC program from a magazine in probably less than an hour.
I'm contemplating actually using it for analysis in one of my next projects on my real C64, again just for shits and giggles.
One of their projects was a video genlock PCB that replaced the 1MHz crystal clock with one that was generated by a PLL (and slightly lower than 1MHz) so that the PAL output of the C64 was synchronized with an incoming video signal that was converted to RGB, selectively mixed with the C64 output, and then sent out as PAL again.
It's how I learned about the existence of PLLs. :-)
Another one of their projects replaced the 6502 firmware of the 1541 floppy drive with a database engine so that database queries were executed on the drive instead of on the C64 CPU.
Amazing stuff.
Edit: the block diagram of the genlock interface: https://www.pouet.net/topic.php?which=12851.
It was customized output of f2c, and I had Linux and Cygwin 32-bit binaries.
It's probably still floating around somewhere.
They really liked me. Everybody ran it from ~me.
I wish I could say that the world has become less reliant on me. It has not.

All the article demonstrates is the practicality of analog design on the Amiga back in the day, which is only relevant now in unlikely and catastrophic forced retrocomputing scenarios; other Amiga software, such as exquisite graphics editors, has retained much more of its usefulness.
