Vivado 2014.4 deprecated command 'export_hardware' is generating incorrect output files


When using the command 'export_hardware' I see the following warning:

WARNING: [Common 17-210] 'export_hardware' is deprecated, please use 'write_hwdef' for pre synthesis export and 'write_sysdef' after bitstream instead.

Can I still use this command in Vivado 2014.4?


Even if deprecated, the command will execute and generate output files.

Those files are incorrect and some clock settings might be wrong.

For example, if you base your design to the Xilinx zc706 board and change the CPU clock to 800MHz, all of the clock settings for the ARM PLL are incorrect.

The work-around is to use the appropriate commands:

write_hwdef -force  -file  (to write .hdf)
file copy -force  (to copy .sysdef to .hdf)
