При программировании потоковой модели автомата возникла потребность в тактировании а именно:

library ieee;

use ieee.std_logic_1164.all;

use ieee.std_logic_unsigned.all;

 

entity MY_STREAM is

port(

DL : in std_logic;

M : in std_logic;

C : in std_logic;

R : in std_logic;

Q0 : out std_logic;

Q1 : out std_logic;

Q2 : out std_logic

);

end MY_STREAM;

 

architecture MODEL of MY_STREAM is

SIGNAL F1,F2,F3,F4,F5,F6,F7,F8,F9,F10 : STD_LOGIC;

SIGNAL NM,NR,NC,NDL : STD_LOGIC;

SIGNAL J0,J1,J2,K0,K1,K2,NQ0,NQ1,NQ2,NQ3: std_logic;

SIGNAL QV0,QV1,QV2,QT0,QT1,QT2: STD_LOGIC;

BEGIN

NQ0<=NOT QT0 AFTER 22 NS;

NQ1<=NOT QT1 AFTER 22 NS;

NQ2<=NOT QT2 AFTER 22 NS;

NM<=NOT(M) AFTER 22 NS;

NC<= NOT© AFTER 22 NS;

NDL<= NOT( DL) AFTER 22 NS;

F1<=(NM AND QT1) AFTER 22 NS ;

F2<=(QT1 AND QT0)AFTER 22 NS ;

J2<=F1 OR F2 AFTER 22 NS;

F3<=NM AND QT0 AFTER 22 NS;

F4<=NQ2 AND QT0 AFTER 22 NS;

J1<=F3 OR F4 AFTER 22 NS;

F5<=M AND NQ2 AFTER 22 NS;

F6<=NM AND DL AFTER 22 NS;

J0<=F5 OR F6 AFTER 22 NS;

K2<=M AND NQ1 AFTER 22 NS;

F7<=M AND QT2 AFTER 22 NS;

F8<=QT2 AND NQ0 AFTER 22 NS;

F10<=M AND QT0 AFTER 22 NS;

F9<=NM AND NQ0 AFTER 22 NS;

K1<=(F7 OR F8 OR F9 OR F10) AFTER 22 NS;

K0<=M OR NDL AFTER 22 NS;

 

QV0<=(R AND ((J0 AND NOT(QT0)) OR (NOT(K0)AND QT0)AND RISING_EDGE(NC)) ) ;

QV1<=(R AND((J1 AND NOT(QT1)) OR (NOT(K1)AND QT1)AND RISING_EDGE(NC)) ) ; --неверный тип boolean нужен std_logic!

QV2<=(R AND((J2 AND NOT(QT2)) OR (NOT(K2)AND QT2)AND RISING_EDGE(NC)) ) ;

 

 

END MODEL;

 

 

 

Подскажите как задается тактирование в потоковых моделях. Я так понял нельзя использовать условные конструкции, функции итд. только логику
