Всем привет описываю проект на VHDL , в проект входит описание автомата. На временных диаграммах состояние автомата обозначается как наинициализированное , если убрать память ( закоментировать) , то времянки начинают показывать первоначальное значение, пожалуйста подскажите что я делаю не так ?

TRIG1_AVT : LATCH
port map( CLK => CLK,D => exсit_fun_line(0),Q => state_line(0));
TRIG2_AVT : LATCH
port map( CLK => CLK,D => exсit_fun_line(1),Q => state_line(1));


START : process

end process;


если закомментировать:

TRIG1_AVT : LATCH
port map( CLK => CLK,D => exсit_fun_line(0),Q => state_line(0));
TRIG2_AVT : LATCH
port map( CLK => CLK,D => exсit_fun_line(1),Q => state_line(1));

 , то времянки начинают, что то показывать, где я ошибся???
