![]() ![]() K-Map and simplified equations for part 2 (20 pts) 6. Print-out of your working circuit for part 1 (20 pts) 4. Be sure to read circuit requirements at top of page 1.(20 pts) 3. Save files from part 1 and part 2 in a new “Lab2” folder under “IC220” in your X drive. Label the circuit and the page in accordance with the specifications in the tutorial. For instance, to test if 102 (decimal 2) is less than 112 (decimal 3), you would click on the “2” on the first (WX) hex keyboard and click on “3” on the second (YZ) hex keyboard and observe the output. Test using 0, 1, 2, and 3 on the hex keyboards. Hook Y and Z up to a different Hex keyboard, like you did for W and X. Ignore the single input on the bottom of the hex keyboard. You’ll need to decide exactly which output goes to W and which to X. Hook W and X up to the two least significant outputs of one Hex keyboard (the other two outputs will not be connected to anything). Note: this example just demonstrates how the hex keyboard works – it is not exactly how you will use it (see details below). This keyboard has 4 outputs on the right hand side – the lowest one is the least significant bit. Instead, use two “Hex Keyboards” (available under the “Simulation IO” library). ![]() Do not use binary switches for the inputs W, X, Y, Z. Implement and test the circuit using Logic Works. 01 is not less than 01, so LessThan is 0. Inputs: W (high order bit of number #1), X (low order bit of number #1), Y (high order bit of number #2), Z (low order bit of number #2), Output: LessThan – true if WX2 < YZ2. You wish to compare two 2-bit numbers and decide if the first is less than the second. (When you are ready, start a new file – do not include this in your previous file). ![]() You will submit this file later, together with part 2. Test your circuit Label the circuit and the page in accordance with the specifications in the tutorial. Suggested method: Select your components and add them to the schematic Add switches for I/O Add and label wires to connect the devices Add probes for outputs and label the outputs. You must use binary switches for inputs W, X, and Y. Using LogicWorks, implement and test a circuit for the following: y = (W Be sure to save your files on your X drive, not on the local computer, or else you may lose your work. It is highly recommended that you label and probe/switch your signals first, rather than at the end, to facilitate testing. 4) The files you submit must exactly match the printouts you turn in. 2) All outputs must be labeled and have probes attached. Requirements for Logic Works Circuits: 1) All inputs must be labeled and have switches (or hex keyboards) attached. However, if you wish to install on your own PC to work outside of class, see the online instructions: In the lab room, you don’t need to install LogicWorks. Lab #2 Familiarity with LogicWorks and Schematics Start during lab and finish on your own time. ![]()
