In Vivado 2015.3 or Vivado 2015.4, if I generate a Trial license using the option "Start Now! 30 Day Trial (No Bitstream)" from the Vivado License Manager (VLM) the generated license has an invalid version limit (2015.07).
This version limit works with Vivado 2015.2 and earlier but not with Vivado 2015.3 and later.
This issue will be resolved in Vivado 2016.1.
To work around this issue, please generate a 30-day evaluation license.
