Return statement finishes the execution of a subprogram and supports jump to the end of a subprogram. If return statement is inside subprograms it can be used to inner subprogram. This statement should be used in function. The syntax is :
return expression ;
procedure RS_FF ( signal S, R: in BIT; signal Q, NQ: inout BIT) is begin if (S = '1' and R = '1') then report "forbidden state: S and R are equal to '1'"; return; else Q <= S and NQ after 5 ns; NQ <= R and Q after 5 ns; end if; end procedure RS_FF;
