title: How to change signal value instatntly?
body: <pre><code>if(rising_edge(clk)) then        
    count := count + 1;
    if count = 3 then
      enable &lt;= 1;
    elsif count = 6 then
      enable &lt;= 0;
      count := 0;             
    end if;
  end if;
  
  if enable = 0 then
    a0i &lt;= a_0;
    boi &lt;= b_0;
  end if;
  
  if enable = 1 then
    a0i &lt;= a_1;
    boi &lt;= b_1;
  end if;
  </code></pre>
  
  <p>All are signals except the count. Value of a0i and boi should response as soon as enable becomes either 0 or 1. I tried using the variable. but it can not allow me to use out side the process.
