I have an exam tonight and I'm reviewing my midterm exam. I got this question completely wrong, with no solution given.
b) [10 marks] Consider implementing the logic formula 'signal 1' below as a hardware circuit without any optimization. You have 2-input 'AND' gates that settle in 125 ps, 2-input 'OR' gates that settle in 150 ps, and infinitely fast wires. After all (original) inputs have been asserted, how long does it take the circuit to settle? Show any numerical calculations. signal 1 = (p \/ q \/ r) \/ (s /\ t) ans: ____ ps
I had no idea what to do so I simply multiplied every AND gate I saw by 125ps and every OR gate I saw by 150ps. I know this is not how to do it because of the number of gates. Can someone please explain this problem to me?
