body: <p>I'm getting the following error when I run the simulation.</p>
  <pre><code>ERROR: [Common 17-39] 'launch_simulation' failed due to earlier errors.

  <p>This project worked fine, but after reinstalling the same Vivado version, I keep getting errors when running the simulation. I have searched and searched several times and places, there are many who end up with this error, but got different suggestions. I honestly do not know what this error means.</p>
  <p>The simulation referred me to the behav folder to open the elaborate log for more information about the error.</p>
