Lab 3

Name ________________________

A1. F(w,x,y,z) = (0,2,4,6,8,9,10,11,12,14)

A1a. Draw the K map for both F and F'.

A1b. Draw the circuit for the following realizations for F(w,x,y,z):

1. AND-OR (SOP)

2. Nand-NAND

3. AND-OR-INVERT (AOI)

4. OR-AND (POS)

5. NOR-NOR

6. OR-AND-INVERT (OAI)

A1c. Realize circuit numbers 2, 3, 5 and 6.

A2. F(A,B,C,D) = (0,2,4,5,7,8,15)

d(A,B,C,D) = (1,10)

Realize a SOP and POS circuit for the reduced version of the above

function.

B. Write HDL with stimulation for a BCD ripple counter as used in lab 2. Use the 4 bit binary ripple counter HDL module handout as the basis. Report should contain source code plus Verilog picture of simulated timing and report diagram.
