title: always block event list if variable is used similar to generate statement
body: <p>Consider code as follows:</p>
  
  <pre><code>   reg [2:0] cnt;
     // a is an input (say 4 bit) to design and being assigned after some manipulation 
     // to some other variable  
  
     always @(a)
        for (cnt = 0; cnt &lt; 4; cnt = cnt+1) begin
            //some operation involving a [bitwise]
        end
  </code></pre>
  
  <p>Now as you can see I didn't include cnt in event list of always block as cnt is not referenced / assigned outside always block and is completely iterated through with for loop</p>
  
  <p>My question is should I have cnt on event list?</p>
