- 1 - 1. (10 points) Determine if the circuit below is subject to internal hold time violations. If so, show how to modify the circuit to eliminate the hold time violations. If not, explain why not. Assume that the flip flop setup time is 2 ns, the hold time is 1 ns, that gate delays for simple gates can range from .3 ns to 1.5 ns, that gates with 3 or 4 inputs have twice as much delay as simple gates, that the flip flop propagation delay can range from 1 ns to 4 ns and that the clock skew is 1 ns.

Unformatted text preview: that gate delays for simple gates can range from .4 ns to 1.5 ns, that gates with 3 or 4 inputs have twice as much delay as simple gates, that the flip flop propagation delay can range from 1 ns to 4 ns and that the clock skew is 1 ns. - 3 - 3. (10 points ) Consider a synchronizer used to synchronize an asynchronous input signal. Let the average time between changes of the input signal be 50 microseconds. Let the flip flop parameters be T = 3 ns and τ = 2 ns. If the clock period for the synchronizer is 10 ns, what is the mean time between synchronizer failures? What is the smallest clock period (to the nearest ns) for which the mean time between failures is 10 years? What is the smallest clock period for which the mean time between failures is 10,000 years?...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
