https://wokwi.com/ is great for simple, digital only stuff.

https://fritzing.org/ will kind of lay out the PCB for you, but it's kind of a pain in the ass.

Wokwi and Fritzing are more "Breadboard Simulators" than real circuit simulators, but they do have their place.

Try https://fritzing.org/ for layout on breadboards.

Looks like fritzing

Fritzing is open-source, so you can just download it from github: https://github.com/fritzing/fritzing-app and build it yourself. Might be worth a buck or two to download a pre-built version though...

For designing them there are various tools out there. Personally I find https://easyeda.com/ and https://upverter.com/ easier to get started with. Other popular option (but with a much steeper learning curve) are kcad, but I have always found that to be clunky UI. https://fritzing.org/ is another local option that is easy to use but last time I tried it would crash on me all the time making it basically unusable - maybe it has improved since I last tried it.

In the past, I have used fritzing.

Try https://fritzing.org/

My older design used shared RAM, again with separate buses and the ROM on the CPU side: https://github.com/gfoot/compvideo6502

I used it for this project, among others - unfortunately the repository doesn't contain images of the layout, but I think it's there in Kicad format at least: https://github.com/gfoot/compvideo6502

Oh cool, glad you find the videos useful! I don't think this decimal idea came from me though - my favourite way to do this is using down-counters for timing, and up-counters for addresses. It eliminates most of the wiring, lets you use a compact memory layout, and sets you up well for things like split screens and hardware scrolling. It's also simple to configure the down-counters from registers so you can make everything software-selectable if you want to. See here for example: https://github.com/gfoot/compvideo6502

It's what U19A and U19B are doing in this schematic, in the middle of page 7: https://github.com/gfoot/compvideo6502/blob/master/images/compvideo6502_schematic.pdf
