Answer / anuprita
In circuit designs, clock skew is a phenomenon in
synchronous circuits in which the clock signal arrives at
different components at different times. This can be caused
by many different things, such as wire-interconnect length,
temperature variations, variation in intermediate devices,
capacitive coupling, material imperfections, and
differences in input capacitance on the clock inputs of
devices using the clock.

Answer / gogulnath
skew is the phenomena which clock dint take equal time to
reach the synchronous flip flop,it takes diff delay to
diff flipflops due to the material imperfection,wired
length,temparature etc,

Answer / himali
Clock skew is the phenomenon wherein clock signal arrives
at different components at different times.
There are two types of clock skews. Positive clock skew
means that clock siganl reaches receiving register faster
than the register that sends the data to the receiver.
Negative skew is the opposite.

Answer / anupriya
In ckt design clk skew is a phenomenon in synchronous ckts
in which the clk signal arives at different components at
diff time.

Answer / madhu
When a clock is triggered, if it reaches first to
destination and next to source then we have a loss of
data,or if it reaches first to source and later to
destination we have a wrong result .this is called Clock
skew,so it is necessary to a clock to reach simultaneously
to source and destination.
