Question

You are to design a circuit, and model using HDL, that 1) adds two three bit unsigned binary

numbers, 2) includes a flag to determine when a overflow occurs, and 3) includes a flag

indicating whether the resulting sum is an even or odd number. The overflow output should be

connected to a red LED, and the even/odd output connected to a yellow LED. If an overflow is

detected the red LED should turn on. When an even sum occurs the yellow LED should be off

and turn on when a odd sum occurs. The LEDs operate with 2.5 volts; 5 volts will burn them out.

Note you will not model the LED portion of your circuit in HDL, but you will connect the LEDs

and associated circuitry to the schematic diagram of your HDL model.

You should create a test bench and test your design by completing the sums below.

000 + 000

010 + 001

011 + 011

111 + 001

Your inputs and outputs should be defined as follows:

A[2:0], B[2:0] Represent your binary inputs, 0 defines least significant bit

Sum[2,0] Represents the output sum

O Represents the overflow flag, no overflow = 0

P Represents the even/odd flag, even = 0

1. Describe the functionality of you design

2. Define all inputs and outputs on your schematic diagram

3. Include information such as Boolean expressions, truth tables
