Vivado requires to explicitly set the VHDL version to 2008+ if VHDL2008 features are being used in design files.
This might be solved in multiple ways:

  • Worst but fastest: Set all files to VHDL2008 by adding following line to vivado.jinja. This will likely not break anything and support VHDL2008 in addition, but is highly bodgy. set_property file_type {VHDL 2008} [get_files -filter {FILE_TYPE == VHDL}]
  • Reasonably easy: Add a new function to set VHDL version explicitly for all files.
  • Most effort but probably best: Implement both setting the version for all files + per each file add command.

I will probably implement this by myself when I find the time, so let me know before you start so we can avoid duplicate work :)

Hi @gts-bzi
I'm considering two things:

  • Add a general-purpose set_option method.
  • Add an options parameter in the add_<HDL> methods.
    In the meantime, you could use a hook:
    prj.add_hook('precfg', 'set_property file_type {VHDL 2008} [get_files -filter {FILE_TYPE == VHDL}]')
