2 Seven Segment Display Used for output of a single decimal digit Driven by a binary coded decimal (BCD) nibble A separate set of combinational logic turns on or off each segment to create the digit display

3 Seven Segment Display

4

5 Seven Segment Display Driver

6 Seven Segment Display Truth Table for Seven Segment Display Driver

7 Seven Segment Display Logic Seven combinational logic circuits - one for each segment Look at the logic for segment e – when is it on? A B C DSum of Product Terms L L L LA B C D L L H LA B C D L H H LA B C D H L L LA B C D How to factor this sum in order to simplify?

8 Karnaugh Map for Segment e A B C D Put down all the 1’s for D, C, B, A = 0 through 9 Then, fill in 0’s for all other valid BCD input values

9 Don’t Cares in Karnaugh Map That takes care of 10 out of 16 combinations What about the other 6? They are “don’t cares” A B C D XX X X X X 0 0

10 Karnaugh Map for Segment e Now we loop the largest areas that we can Use “don’t cares” as 1’s if loops can be larger Segment e = B D + C D A B C D X 1 X X0 0 X X X 0 0

11 Segment e Logic Circuit ABCD BCD Inputs e C D B D Not Used

12 Test Segment e Logic Circuit 0000 BCD Inputs e = 1 C D = 0 B D = 1 Not Used e

13 Test Segment e Logic Circuit 0001 BCD Inputs e = 0 C D = 0 B D = 0 Not Used e

14 Test Segment e Logic Circuit 0010 BCD Inputs e = 1 C D = 1 B D = 1 Not Used e

15 Test Segment e Logic Circuit 0011 BCD Inputs e = 0 C D = 0 B D = 0 Not Used e

16 Test Segment e Logic Circuit 0100 BCD Inputs e = 0 C D = 0 B D = 0 Not Used e

17 Test Segment e Logic Circuit 0101 BCD Inputs e = 0 C D = 0 B D = 0 Not Used e

18 Test Segment e Logic Circuit 0110 BCD Inputs e = 1 C D = 1 B D = 0 Not Used e

19 Test Segment e Logic Circuit 0111 BCD Inputs e = 0 C D = 0 B D = 0 Not Used e

20 Test Segment e Logic Circuit 1000 BCD Inputs e = 1 C D = 0 B D = 1 Not Used e

21 Test Segment e Logic Circuit 1001 BCD Inputs e = 0 C D = 0 B D = 0 Not Used e

22 Test Segment e Logic Circuit 1010 = DON’T CARE! BCD Inputs e = 1 C D = 1 B D = 1 Not Used e

23 Can we do better than the map result? Sometimes, if we look at the Boolean equation from the Karnaugh map for segment e: Segment e = B D + C D It can be factored: Segment e = (B + C) D Simpler Logic Diagram (Product of Sums): e B C D
