What can be used to model and calculate a circuit diagram?

Question

Arduino

Good time!
I myself am a radio engineer by education, but all the time I worked as a programmer, so a lot has already been forgotten. But now the task has arisen, to develop and simulate a simple circuit with diodes, resistors and simple logic such as multiplexers and generators.
This circuit is conceived to connect to an arduino-like scarf via gpio (most likely). I would like to debug on the model, and only then quickly solder it, than debug it with a soldering iron :)
Is there a tool with which this could be done with little bloodshed?
I know that matlab can do almost everything. If anyone solved similar problems in matlab, please tell me the package.
Thank you all for your help, have a great day!
UPD:
Found a list of modeling CADs: cxem.net
Which ones are the most popular right now?
For myself, I have so far noted the Proteus and Multisuit NI systems.

Answer 1

I have the same situation, a radio engineer by education, but I work as a programmer and from time to time I have to design small circuits.
I came to the conclusion that there is nothing better for modeling Proteus, if necessary, you can also separate the board.

Answer 2

At the institute, I used Orcad Capture and Microcap for analog simulation on labs. The first is considered almost the most reliable tool for modeling. Get ready to have to seriously delve into the various parameters of semiconductor devices.
If this is a one-time project for you, then it may not make sense to poke around in the models, anyway, theory and practice will not coincide the first time, and if you want, you don’t want to have to debug on hardware . If you do this, first put variable-value trimmer passive elements.
As for Proteus and analog simulation, I doubt it.

Answer 3

peacefulatom rightly noticed - Orcad from shareware is almost the best and free simulator. In addition, it came across a manual in Russian. And somewhere else, a training manual from institute times remained.

Answer 4

Kind of weird-

a radio engineer by training, but worked as a programmer all the time

and do not know the tools for calculation and modeling? Okay, it happens. I won’t tell you about matlab, I practically don’t use it (unless I just calculate something). You can advise Proteus - it has a lot of things, it works great with logic and microcontrollers.

Answer 5

Proteus (on the plus side - built-in controller simulators, at least AVR (just one of them in arduino, although there is a slightly special case), with the ability to upload firmware to them) or Altium Designer (I have never tried its simulator, but I know what he is)

Answer 6

If arduino-like doesn't mean an Atmel controller, then I don't know.
If all of them are from Atmel, I advise you to use the AVRStudio + Proteus bundle through the installed plugin in the studio.

Answer 7

If you work with AVR and something simple enough - this is Proteus ISIS.
If you have to solve more complex tasks - this is OrCAD. In it you will find such simulation modes as analog, discrete and symbiosis of the first two.
I also want to advise NI Multisim - for me it turned out to be intuitive, though after learning OrCAD.

Answer 8

if hardcore, then Altium,
but in general there is an online utility https://123d.circuits.io/ in it you can simulate different things and connect an arduino and write a code
