Hmmm... I do see the following in vhdl/src/std/textio.v93
-- UNIT must be a unit name declared in std.standard. Of course, no
rules
-- in the core VHDL language prevent you from using a value that is not a
-- unit (eg: 10 ns or even 5 fs).
-- An assertion error message is generated in this case, and question
mark
-- (?) is written at the place of the unit name.
procedure write
(l: inout line; value : in time;
justified: in side := right; field: in width := 0; unit : in TIME :=
ns);
Oh, is it your typo?
You wrote "filed" instead of "field".
