Re: [sv-ac] RE: Call to vote: Due March 2 (resend, typo fix)

We could make a reference to section * 5.7.1 Integer literal constants*
That states: "If the size of the unsigned number is smaller than the size
specified for the literal constant, the unsigned number shall be padded to
the left with zeros. If the leftmost bit in the unsigned number is an x or a
z, then an x or a z shall be used to pad to the left, respectively. If the
size of the unsigned number is larger than the size specified for the
literal constant, the unsigned number shall be truncated from the left."

Thus, - $countbits (expression, 2’b1) returns the number of bits in
expression having values 1 or 0.
Per 5.7.1, this is equivalent to $countbits (expression, 2’b01)
