•Write out the two rules for FF state assignment based on next states and the one rule for outputs. Indicate the order of importance of the rules and which rule should be considered first when doing FF state assignment. •Explain why we care about FF state assignment and how the target hardware of a FGPA verses a new IC can change how we might think about FF state assignment. •Explain in a few sentences why we can use a K-Map to help us do FF state assignment. •Use the state table in figure HW14.1 to do FF state assignment with the help of a K-Map in figure HW14.2. Note that we are not told what the state machine does. Be sure and list how you applied the rules and the order of importance given to each application of a rule. $S_0$
