Здравствуйте!

1. Исправьте пожалуйста, чтобы оно скомпилировалось.

2. Почему нельзя объявить сигналы в теле процедуры?

signal C_S: std_logic;
signal C_R: std_logic;

Здравствуйте!

 

Описание портов:

CLK − вход тактовой частоты;

Reset – вход асинхронного сброса;

J – J-вход;

K – K-вход;

Q – выход.

 

library IEEE;
use IEEE.std_logic_1164.all;
entity JK_tr is

      port (J: in STD_LOGIC;
            K:in STD_LOGIC;
            CLK:in STD_LOGIC;
            Reset: in STD_LOGIC;
            Q: out STD_LOGIC);

end JK_tr;
architecture JK_tr of JK_tr is

      begin
      process(clk, reset) is
      variable Qint: STD_LOGIC;
      begin
      if (reset ='0') then Qint:='0';
      elsif (CLK'event and CLK ='1') then
      if (J='1' and K='1') then Qint := not(Qint);
      elsif (J='0' and K='0') then Qint:=Qint;
      elsif (J='1' and K='0') then Qint:='1';
      elsif (J='0' and K='1') then Qint:='0';
      end if; end if;
      Q<=Qint;
      end process;

end JK_tr;
