vhdl-highlight-translate-off

vhdl-highlight-translate-off is a variable defined in `vhdl-mode.el'.
Its value is

nil

Documentation:
Non-nil means background-highlight code excluded from translation.
That is, all code between "-- pragma translate_off" and
"-- pragma translate_on" is highlighted using a different background color
(face `vhdl-font-lock-translate-off-face').
Note: this might slow down on-the-fly fontification (and thus editing).

NOTE: Activate the new setting in a VHDL buffer by re-fontifying it (menu
entry "Fontify Buffer").

You can customize this variable.
