Electronic Schematic Package?


What are the go-to choices for drawing Electronic schematics these days?

A thought, and market uncurled itself in my brain recently. I want to implement it in an fpga, but I still find it handiest to design in the familiar building blocks as a transitional step. I'm looking for the circuit design package to do that. I have 'dia' which I have used before and have yet to build it.

As working systems, I have Slackware-current, and Mint-19. As very second class choices there also Vista or Windows 10 VMs, but they only get one core and 3 Gig of ram, so they're more resource challenged than the already unimpressive box, now in it's 6th year.

This article may help: https://www.allaboutcircuits.com/tec...sign-on-linux/

Scroll down the the section titled "Schematic Capture and PCB Design."

A web search for "electronic schematics linux" will turn up additional options.

That's a very useful article, thank you.

In 1980 - 82, I assisted in an inverter project. In a word, it was a brilliant Analogue Design, but it bombed and was never made commercially. Patents are expired now, and I thought of converting to FPGA. I had a different application in mind. Changing the configuration on the Analogue version also meant calculating and changing resistor values :-/. As we were finishing up with it, Analogue Devices replaced our large board of opamps and logic with a single (probably obsolete) IC. All that this could add was the (admittedly excellent for the time) over-current control strategy.

In addition to the basic inverter, I would have to add regeneration, a configuration layer for voltage, current, and frequency, and also switch to modern power devices. This all gets a little big for one severely limited guy operating on his own. It's not the technical challenge that scares me, but it is reinventing the wheel, and the businessman in me says no.

I was interested to see Kicad - that jogged my memory. I used that in 2013 to build an OptoElectronic Transceiver using HEMTs and 74AUCxx chips that operated at 250Mhz. There was very peculiar forces at work in my College for two years, as the course was shortened by a year mid way through, and I was unlucky enough to be caught there. VHDL was a problem, as was project time. Only one lecturer was prepared to oversee my work, and I taught him rather than him teaching me :-/. But I used Kicad for the PCB - And was impressed with it then. The resulting pcb handled 250Mhz without issue, and managed usable signal transmission over 500 metres of POF.
