hi....

If a design has reset pin, then it will affect input pin or output pin or both?
 

Reset pins are used to put all your registers, FSM states into known state.
Code: 
 if (reset == 1'b0)
   a <= 1'b0;
else
   a <= b;
a - output; b as input.when reset is applied a will be assigned to 0. a will not vary wrt b until reset is removed.
