title: How to generate .xst file from command line + Xilinx-ISE
body: <p>I am trying to learn how to generate bit files from command line. Is there a way to generate the .xst script file from command line tools? I can only find mention of it being something that the GUI auto-generates.</p>
  
  <p>To add some context, I build and generate a bit file for a simple design in the GUI then use the 'View Command Line Log' tool to generate the commands the tool used. Then use "Cleanup Project Files". I am just trying to execute the same commands manually from the command line. The first command is:</p>
  
  <pre><code>xst -ifn "C:/Users/Documents/XilinxProjects/SingleItemTest/item.xst" -ofn "C:/Users/Documents/XilinxProjects/SingleItemTest/item.syr" 
  </code></pre>
  
  <p>Which gives me:</p>
  
  <pre><code>ERROR:Xst:427 - Entry File C:/Users/Documents/XilinxProjects/SingleItemTest/item.xst not found
  </code></pre>
