Question 3.

Question :

(TCO 3) Determine the VHDL assignment statement at Z with respect to the inputs.

Student Answer:

Z <= (A NAND B) AND (C OR D);

Z <= NOT A AND B AND (C OR D);

Z <= NOT (A AND B) AND C OR D;

Z <= NOT A AND B AND C OR D; Instructor Explanation:

TP1 <= (A NAND B); TP2 <= (C OR D); Z <= (A NAND B) AND (C OR D);. Refer to the Week 1 Lecture for additional information on VHDL.

Question 4.

Question :

(TCO 3) Determine the Boolean expression at Z with respect to the inputs.

Student Answer:

Instructor Explanation:

Z is the output of a NAND gate. The Boolean operator for the NAND gate is , there should be an inversion bar over the entire expression, and the inputs are (A + B) and (C D). Refer to Chapter 3
