Verilator for attempts to track the minimum width of unsized constants
Verilator attempts to track the minimum width of unsized constants
and will suppress the warning when the minimum width is appropriate to
fit the required size.

The recommendation is to fix these issues by:
* Resizing the variable or constant. E.g. :code:`2'd2` instead of :code:`3'd2`.
* Resizing the variable or constant to match the needed size for the
expression. E.g. :code:`2'd2` instead of :code:`3'd2`.
* Using :code:`'0` or :code:`'1`.
* Using :code:`'0` or :code:`'1` which automatically resize in an
expression.
* Using part select to narrow a variable. E.g. :code:`too_wide[1:0]`.
* Using part selects to narrow a variable. E.g. :code:`too_wide[1:0]`.
* Using concatenate to widen a variable. E.g. :code:`{1'b1, too_narrow}`.
