Hi All,


Please tell me what will be the max freq for this circuit to work?

here clock buffer delay is 8 ns.



thanx jit
 

it seems that this circuit can't work, because the hold time requirment is not met

hi jiten,
You have to fix the hold first to make the circuit work , i,e add a delay of 3 ns to the combo, then it can work at a ck period of 3ns.
 

Dear Raju,

with addition of just 3 ns in combo delay will not make this circuit to work because in this case hold will violate with 2ns.

here we have to increase the combo delay by 5 ns so both setup and hold will meet their requirement without violation.


thanx
jit
