  1. In the ideal world, you want to test all possible scenarios of a chip.
  2. Unfortunately, we live in the real world, and that's just not possible. I'm
  3. going to illustrate the impossibility with a simple device, a 32-bit adder.
  4. [NOISE]
  5. It has input A with 32-bits and input B with another 32-bits, and then an
  6. output alpha, 33-bits. How many test vectors does it take to simulate such a
  7. device exhaustively? All combinations. A test vector is basically the input
  8. values you apply to input A and B. Go ahead, figure it out, and put the value
  9. in the field.
