Regarding reset pin in the Design

[Manochitra]

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.

 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.
