nil

• This variable is safe as a file local variable if its value
  satisfies the predicate `verilog-booleanp'.

Documentation:
Non-nil means background-highlight code excluded from translation.
That is, all code between "// synopsys translate_off" and
"// synopsys translate_on" is highlighted using a different background color
(face `verilog-font-lock-translate-off-face').

Note: This will slow down on-the-fly fontification (and thus editing).

Note: Activate the new setting in a Verilog buffer by re-fontifying it (menu
entry "Fontify Buffer"). XEmacs: turn off and on font locking.

You can customize this variable.
