Simulink Fixed Point vs Fixed point toolbox

Hi I wanted to know if there is any difference between Simulink Fixed point and Fixed Point Toolbox. I recently requested for Simulink fixed point from Matlab and what i received is Fixed Point toolbox.

Simulation with fixed point requires the Fixed Point Designer Toolbox, which appears to be the same thing as Fixed Point Toolbox.

There is a small amount of built-in fixed point available without the Toolbox, corresponding to some of the smaller integer data types.
