How would you describe setup time and hold time, and could you explain the causes of their violations and measures to prevent them?

Anonymous · Accepted Answer

setup time : It is the  minimum time input must be stable before arrival of
clock edge where for hold time it is the minimum time input must be stable after
arrival of clock edge .These violations occur whenever input changes during the
setup and hold constriants .setup time can be minimized by increasing the clock
period and decreasing the the clock2q delay ,combinational delay and setup
time.hold time can be minimized by decreasing the hold time and increasing C2Q
delay and combination delay.

setup time is minimum time for the data to enter before the active clock edge to
be stable while hold time is the minimum time required for the data to be stable
after active clock edge.
violations for hold time are due to data changing too early while for setup time
its due to the fact that data came in late .
for minimizing setup we need to take care of the logic and the clk while for
hold we need to make sure to get rid of any unintentional latches since they are
the main reason usually.
