2.2. VHDL Programming Language

Try these first

1. 1.

   What does VHDL stand for?

   Hint

   What is the full form of VHDL?

2. 2.

   What is an entity in VHDL?

   Hint

   Think about what connects external elements to internal logic.

3. 3.

   What is the primary purpose of VHDL?

   • To describe analog circuits
   • To model digital circuits
   • To perform mathematical operations

   Hint

   Remember VHDL's focus areas.

4. 4.

   True or False: VHDL language supports only one data type.

   • True
   • False

   Hint

   Think about what types we discussed.

5. 5.

   Design a VHDL code for a 2-input XOR gate. Explain your design choices.

   Hint

   Recall how XOR functions in terms of AND and NOT.

6. 6.

   Explain how you would modify the existing AND_GATE code to accommodate a 3-input AND gate.

   Hint

   Consider how additional inputs affect the logic.
