The purpose of this question is to give you some practice on timing calculations, as discussed in class.Consider the circuit shown below.

Answer the following questions, using the following data:

• ·Clock skew = 750 ps
• ·T_clock_Q = (300 : 450 : 950) ps in (min:typ:max)
• ·AND delay = (70 : 120 : 210) ps
• ·OR delay = (50 : 110 : 200) ps
• ·Mux delay from D0 or D1 = (40 : 90 : 180) ps
• ·Mux delay from S = (30 : 80 : 170) ps
• ·T_setup = (100 : 200 : 300) ps
• ·T_hold = (200 : 300 : 400) ps

What is the fastest possible clock that allows worst-case circuits to work correctly without setup violations? Give your answer as a clock period ps. Do not specify the units. E.g. If the answer is 123 ps, just type in 123
