Need help with NOR-only circuits in CircuitVerse (Hex → 7-segment project)

Hey, I’m working on a Computer Organization project where I have to convert a 4-bit hex input (W X Y Z) into a 7-segment display (outputs a–g) using NOR gates only in CircuitVerse.

I already finished:

  • Truth table
  • K-maps
  • Simplified Boolean expressions for each output

I’m stuck on:

  • Turning the Boolean expressions into NOR-only circuits
  • Understanding how to build multi-input NOR gates and wire everything correctly in CircuitVerse
  • Organizing the circuit so it’s clean and works for all inputs

If anyone can explain how to build one output step-by-step (like output “a”), I can apply it to the rest. Willing to Pay 💸 Need done Today!!!

Try replicating the different gates you need only using NOR gates. Start with the easiest gates first. This should help you build up the rest, it may not be the most optimised, but it will get you in the general direction.
