Parallel While

Definition​

If you use While outside of a Thread, the VHDL While is used. In that section you can repeat only a finite amount of times. If you want to use this parallel While in a thread, you have to write ParWhile.

Example​

Process() {
    VARIABLE counter : INTEGER := 0; 
    While (counter < 8) 
    { 
        LED(counter) <= '1'; 
        counter := counter + 1;
    } 
}

OR 

Process() {
    Thread {
        VARIABLE counter : INTEGER := 0; 
        ParWhile (counter < 8) 
        { 
            LED(counter) <= '1'; 
            counter := counter + 1;
        } 
    }
}
