This is my 4 to 1 Multiplexor circuit but I need help because it isn't right. Does anyone know what I'm doing wrong? It has to be in Simcir.

No, it's not. I'm self-teaching about Computer Science through a book and I can't seem to figure out the MUX circuit in Simcir.Welcome to AAC!
Is this homework?
The first thing you need to learn is that neatness counts. It makes the circuit easier for us to read and easier for you to troubleshoot connectivity problems.No, it's not. I'm self-teaching about Computer Science through a book and I can't seem to figure out the MUX circuit in Simcir.

Look at the symmetry, or lack thereof, of the select signals.
Please draw it as a normal schematic with right angle connections and a layout that minimizes the length of the connections.
That drawing too convoluted to readily follow.
Not much better. One place to learn how the professionals do it is to look at datasheets.Is this easier to read? I'm not exactly sure the schematics of how to organize the circuit. Thanks to all for the help.
Yes.So I should make it symmetrical? I'm having trouble figuring out which switches connect to which gates.
How did you come up with the connections that you have?So I should make it symmetrical? I'm having trouble figuring out which switches connect to which gates.
As near as I can tell, this Simcir application only does rat's nest connectivity. So the best she can probably do is to position components so as to reduce the chaos as much as she can.Not much better. One place to learn how the professionals do it is to look at datasheets.
How is this relevant to what's wrong with the OP's circuit?
Simcir doesn't let you draw clean schematics. If you're self-teaching, why do you want to use it? There are better free logic simulators.I'm self-teaching about Computer Science through a book and I can't seem to figure out the MUX circuit in Simcir.
I showed that the electronic circuit must consist of inverters and 2-N-HE logic elements. It is also better to break the circuit into smaller blocks. Then it is more understandable. I also demonstrated the functioning.How is this relevant to what's wrong with the OP's circuit?
