I installed Vivado 2014.2 without any errors or warnings.
However, when I open a Vivado project I get a Critical Warning similar to the following:
CRITICAL WARNING: [Project 1-124] XILINX environment variable undefined. Please source the settings script included with your ISE installation before launching runs.
解决方案
This Critical Warning occurs if only UltraScale devices are selected to be installed (i.e. non Virtex-7 or Zync devices).
For UltraScale device installation, there is no need to create an ISE environment to support legacy designs that might have been created in ISE.
Therefore the installer correctly does not install the ISE environment.
However, a check is still being done in Vivado for the existence of an ISE environment.
The critical warning can be safely ignored and has been removed in Vivado 2014.3.
