Creating the Full Addre from 2 Half adders and 1 OR gate
In the architecture of Full Adder, declare two components:
- OR gate
- Half Adder
then complete the component instantiation of 3 units U1, U2, U3 (2 Units would be the Half Adder and one Unit would be the OR gate).
You also need to complete the entity and architecture for OR gate component and Half Adder component (that you declared earlier) after the architecture of Full Adder.
