There are several ways to run VHDL-2008 files with Vivado. You can go to the Source File Properties window and set Type: VHDL 2008 from the drop-down of available file types. The Vivado tool sets the file type to VHDL-2008.
You can also set files to VHDL-2008 with the set_property command in the Tcl Console. The
syntax is as
follows:
set_property FILE_TYPE {VHDL 2008} [get_files <file>.vhd]Finally, in the Non-Project or Tcl flow, the command for reading in VHDL has
VHDL-2008 as
follows:
read_vhdl -vhdl2008 <file>.vhdIf you want to read in more than one file, you can either use multiple
read_vhdl commands or multiple files with one command, as
follows:
read_vhdl -vhdl2008 {a.vhd b.vhd c.vhd}
