Its value is

nil

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

Documentation:
Non-nil means to automatically read includes before AUTOs.
This will do a `verilog-read-defines' and `verilog-read-includes' before
each AUTO expansion. This makes it easier to embed defines and includes,
but can result in very slow reading times if there are many or large
include files.

You can customize this variable.
