title: Stop entity generator block then release it upon condition in SimEvents
body: <p>I am using "Time-Based Entity Generator" and I need to control the entities generation. For example, if Simulation Clock &lt; 100 stop generation and else set interarrival time = 1.</p>
  
  <p>I tried this:</p>
  
  <pre><code>if SimClk &lt; 100
  
      IntARR = inf;
  else
      IntARR = 1;
  end
  </code></pre>
  
  <p>It didn't work as when the interarrival time set to be Inf, It stopped generation and cannot return back.</p>
  
  <p>Any help ?!</p>
