HW3: Timing Analysis w/ Clock Skew

Answer the following using Symbolic Expressions Only!!!  :

1. Write the setup and hold timing constraints for the shift register considering the effect of clock skew as specified in the lecture notes

2. How might you have to modify the circuit to ensure that hold time is satisfied. Draw the diagram and show your reasoning mathematically.

3. What is the minimum clock period for a hold-safe circuit (symbolic expression only). This is a little bit tricky and depends on your result from 2!!
