Design the necessary circuit using Logisim to implement the situation described above. Use Kmaps for simplification. Be VERY careful to get the correct functions for your four outputs before simplifying and designing the circuit with Logisim. You should minimize the entire circuit. This means you should look at each function AND its complement to see which combination will give you the minimal circuit. For example, using the functions that represent UL, UR (the complement of UR), LR, and LL (with NOT gates after UR and LL of course) might give the minimal circuit overall. Your circuit should have four inputs and four LED outputs. Your outputs should be such that the LEDs are arranged to light up the dots in their actual places (stack the 4 LEDs into a square.)All inputs should be labeled (in Logisim, not by hand). You can label outputs if you wish, but since you are placing the LEDs in the correct position, that isn't necessary. Please use the labeling for input (and output if you choose) as given above so everyone's circuit is labeled the same. You should also include your name as a label on the circuit. Test your circuit to be sure it is working correctly. Name the file using your first initial and last name followed by 4-2, for example lnull4-2.circ.
