They show how to make a NAND, NOR, and XOR gate. And all you really need for functional completeness is the NAND.

This just doesn’t have the semi-analog stuff like DRAM.

But if I had to do my digital design at the gate level for anything more than like an adder, I’d be pretty over it pretty quickly.

There are those that build entirely by hand; but the more common method is to use tools/mods like MCEdit to copy+paste whole sections of blocks. Then you can just build out one of each logic gate/larger section and copy+paste it all together into the full creation bit by bit.

I recommend mattbatwings, he actually does design the circuits and just copy and pastes them using world edit tools

In digital logic design, this is called a synthesis tool. In the design of real digital circuitry, you write a code-like hardware description using a language called an “HDL” (hardware description language) such as VHDL or SystemVerilog. Then a program called a synthesiser converts the HDL into a digital circuit.

Each module is designed this way then hooked up using busses and wires.

In real-life, you would then send the generated design to the manufacturing team

That’s why I was unimpressed with Space Engineers programming blocks. They’re nothing more than blocks that execute actual C code you have to write into it; but it’s limited in functions you actually have use of.

It’s not something a non-programmer can use, as they initially lead people to believe prior to releasing the update.

Turing-complete means it’s capable of expressing any possible program, although it only looks at the pure logic, it doesn’t look at timing constraints or resource constraints.

So, the redstone simulation would definitely be too slow to create an actually playable version of Minecraft, and there’s almost certainly other simulation limits you would hit, like e.g. the redstone not fitting into the area the game actually computes, but in principle, you could express all the same logic.
