- The ``blackbox`` attribute on modules is used to mark empty stub modules

string is created that contains all the string from the original entities.
-- In addition to the ``(* ... *)`` attribute syntax, yosys supports
+- In addition to the ``(* ... *)`` attribute syntax, Yosys supports
the non-standard ``{* ... *}`` attribute syntax to set default attributes
