Hello all,
Suppose I am having a D flip flop.
Now what are the parameters those affects the setup and hold time of the same?
If I want to change it, how to change it?

Thanks for the reply,
But this page only defines what is setup & hold time.
It doesn't defines on what parameter both of this timing depends..?
According to my logic: I think setup time depends on the driver strength & hold time depends on the delay of the capture flop...

The latency and rise /fall time of each gate affects these parameters.
IF you design looks like this then it is typical for most CMOS.

Thanks for the reply.
So will there be any way to modify the setup & hold time once after the circuit is made?
