I have Vivado 2014.1 and my design requires vivado2014.2 how can i update my tool online?
This a question for Xilinx. Please check their documentation for details regarding the update process.
My system is updating with 2014.4. Will my hdl-hdl_2014_r2 reference design work with vivado 2014.4.
You will not be able to build the hdl_2014_r2 projects using Vivado 2014.4. You need 2014.2 - it's the only version supported at this moment.
