When I start Vivado from a shell, I see the following warning:
Why do I get this message?
Is there something wrong with my Vivado Installation?
The message can be safely ignored.
Vivado HLS is not expected to be installed with Vivado Design Edition.
However, the startup script incorrectly checks for its existence and issues the warning when it is not located.
This is scheduled to be fixed in Vivado 2015.3.
To avoid the warning message you could set an environment variable named XILINX_VIVADO_HLS to any value.
