Description:

Let's work with the following function: F(a,b,c,d) = ab'cd + b'(c+d)

  1. Draw the K-map for the function F(a,b,c,d).
  2. Write the simplified function from your K-map down.
  3. Draw, on paper, using square blocks for OR, AND, and NOT, your schematic for the two equations (unsimplified but FOILed and K-map simplified).
    For example, if o = a OR b, you would draw the following image:
    OR2.png
  4. Open CircuitVerse: https://circuitverse.org/simulator (Links to an external site.)
  5. Create two separate circuits: one for the unsimplified function, and one for the simplified function. 
    Attach Input as the input to the logic gate system and Output or DigitalLED as the output.
    You will want to label your Inputs to make it easier to check the input values and output value against your K-map.
  6. Test that both circuits output the same value of 1 or ON/HIGH by choosing any minterm in the K-map (set the Input to the corresponding values).
  7. Download a picture of one of the values showing that both circuits output the same value with the same input by going to Tools -> Download Image.
  8. To submit your work, write down your two equations (unsimplified but FOILed and the K-map sim
