The homework is basically this:
Implements a double counter composed of two C1 subcircuits (asynchronous counter
2-bit ascending) and C2 (2-bit descending asynchronous counter). The initial number
C1's account must be 0 (00) and C2's must be 2 (10). When both counters count the same
number, a yellow LED should light up. It also said I need to use two hex digit display in order to saw the number coincide. This is my try but I dont really know where I have to put the led so it light. It is made on logisim that is where my teacher told us to put the code.

Thanks for helping!

 

How might you tell if the two counters are producing the same input?

Hint: You might want to consider a logic gate that outputs one value with both inputs are the same and the other value when they are different.
