Testbench didnt work for my Rnot Snot flip flop

Hello there, i have problem. My tb file didnt work. Can someone please help me and test it?

I have Quartus 13.0 SP1. For simulation i use AlteraSim. Thanks a lot:

VHDL file:

library IEEE; --kniznica IEEEuse IEEE.STD_LOGIC_1164.ALL; --pouzitie IEEE.STD_LOGIC pre vyuzitie STD_LOGIC FUNKCII
entity rs_nand is -- popis entity

      q,qb : out STD_LOGIC); -- VYSTUPY Q QB
end rs_nand; --koniec popisu entity
architecture rs_nand_arch of rs_nand is --popis architektury
signal tmp_q, tmp_qb : STD_LOGIC; -- vytvorenie logickych signalov tmp_q a tmp_qb
