Re: Show HN: BOOLR – A digital logic simulator
#2Last year we wanted to make a working computer in a simulator for a school project. We had learned something about digital logic, and we planned to build a computer in a digital logic simulator. We had tried many simulators, but we couldn't find what we were looking for. That's why we decided to make our own simulator, BOOLR, with electron and JavaScript. Because we were quite new to programming, it was quite buggy and slow, but it was much better looking and easier to use than other simulators.
Now, one year later, we have gained much more programming experience and we decided to start building a second version that is stable and fast enough for professional use. We are really exited for this project. We have huge plans and it will take a lot of time, but we hope we can make a lot of people happy with it and help people learn more about digital electronics.

#3To move components use Ctrl and Left-drag. Also works for the background.

That’s right! You can also scroll around by moving the mouse with the middle mouse button down.

#5Wow, this is pretty cool, I can definitely see myself using this over Quartus for experimentation. It would be even better if it supported displaying logic gates in the ANSI style: https://commons.wikimedia.org/wiki/Category:ANSI_logic_gates

Your work is amazing, very well done.

#8Nice. Good to know that this is a high school project. I was in university already when heavily used Xilinx to wire those logic gates, flip-flop, Mux etc. And burnt it down to FPGA, pretty fun.
Does your high school teach Digital Circuit & Logic Design, like, K-map, Quine–McCluskey?

#9I've used QUCS for this purpopse, which allows inclusion of Verilog/VHDL modules via FreeHDL.

Yes, unfortunately there is no easier option to rewire... We will definitely make a more efficient and more stable wiring system in BOOLR 2.0 with also, for example, options to draw many wires at once.
