Suppose you have a combinational circuit between two
registers driven by a clock. What will you do if the delay
of the combinational circuit is greater than your clock
signal? (You can't resize the combinational circuit
transistors)

Answer / adi

Insert a small buffer to increase the skew between the two
regs. This can be quick fix only in some cases though

Suppose you have a combinational circuit between two registers driven by a clock. What will you do..

Answer / ram

when there is a combo delay which is more than the clock
time period, though all the above can be a solution if the
delay is small, normally they mark it as a multi clock cycle
path.
