4. You are on a performance engineering team helping to design a circuit and trying to determine how fast you can clock your design. The design has a 16-bit flip-flop that has tsv=1ns and thou=2ns. The next-state logic has tsu=3ns and in all the regular use cases, teo=5ns. There is also a very rare, emergency case that is part of the critical path which has tep=8ns, but this almost never happens. At what frequency can we clock the design? Show work. (3 points)
