Its actually 18 bits signed fixed point number, with 8 bits integer and 10 bits fractional.

The sfixed/ufixed types were added with VHDL 2008 (there is a 1993 compatability library). It allows you to represent fixed point numbers a bit more easily (and slightly less confusingly). Positive indexes are the integer part, and -ve are the fractional parts.

eg. res : sfixed(1 downto -2) := "0101";

= 1.25

"0011" = 0.75
