Calculations Level

[AkeemKaleeb]

Hey, everyone! Was wondering if someone could help with the calculations level. Here's what I have so far:

Decoder:

ALU:
https://steamcommunity.com/sharedfiles/filedetails/?id=2902089388

Calculations Level:
https://steamcommunity.com/sharedfiles/filedetails/?id=2902089398

I believe that it should work but it gets an error message of
"Short circuit (outputs: ALU: 0, ALU: 255)

If anyone has any suggestions, please let me know!

Issue is in your ALU. If all inputs are active then there are also multiple switches which are active --> short circuit. The solution is to use a 3-bit decoder in your ALU (instead of all the AND gates) to get the signals for the switches.

Using ANDs in ALU is not that bad. You just have to use 3 input ANDs in all cases. Or use 3-bit decoder as was already mntioned.

Thank you so much! Will work to fix this now. I thought the ALU was too confusing to do it that way and completely forgot about 3-bit decoders.
