560 | ff.has_clk = ff.has_ce = ff.has_clk = false;

This is almost certainly just a typo/copy paste error and objectively
wrong, so just fix it.

string is equivalent to "\0", and is 8 bits wide, so that's wrong.
After this commit, a replication operation with a count of zero is
used instead, which is explicitly permitted per 1364-2005 5.1.14,
and is defined to have size zero. (Its operand has to have a non-zero
size for it to be legal, though.)
