Q:

Puzzle : Blueberries and Cups

Maria have some blueberries and some cups. If she put 9 blueberries into each cup she will have two cups left. If she put 6 blueberries into each cup she will have three blueberries left over.

Answer

The number of blueberries is equal to number of cups multiplied by 4 minus one left.


That is :


      B = 9(C - 2) -> (1)


Then the number of blueberries will be equal to the number of cups times three plus one left.


That is :


      B = 6C + 3 -> (2)


Now substitute the 1st and 2nd equations:


      B = 9(C - 2)


      B = 6C + 3


      C = 7, B = 45.


Therefore Blueberries = 45 and cups = 7.

Q:

What are set up time & hold time constraints? What do they signify? Which one is critical for estimating maximum clock frequency of a circuit?

Answer

Suppose your flip-flop is positive edgetriggered. time for which data should be stable prior to positive edge clock is called setup is called setup time constraint.


Time for which data should be stable after the positive edge of clock is called as hold time constraint.


If any of these constraints are violate d then flip-flop will enter in meta stable state, in which we cannot determine the output of flip-flop.


there are two equation:


1. Tcq + Tcomb > Tskew + Thold


2. Tcq + Tcomb > Tskew + T - Tsetup


Tcq is time delay when data enters the flip flop and data comes at output of flip flop.


Tcomb is the logic delay between two flip flop.


Tskew is the delay of clock to flip flop: suppose there are two flip flop, if clock reaches first to source flip flop and then after some delay to destination flip flop, it is positive skew and if vice versa then negative  skew. 


so if you take 2 eq you will see that setup time is the determining factor of clock's time period.
