Mathworks SDR e-book failure: "The Fixed-Point Designer must be available to construct an MFILT.CICINTERP filter."

I'm doing the e-book offered via https://www.mathworks.com/campaigns/offers/download-rtl-sdr-ebook.html

This is "

Software-Defined Radio Using MATLAB, Simulink, and the RTL-SDR

"

I am running the example 11.10 using matlab v2020a and am getting the message:

The Fixed-Point Designer must be available to construct an MFILT.CICINTERP filter.

The book describes its requirements as DSP, Communications and Signal Processing toolboxes.

Now, do I need to buy another toolbox?

Hi David,

Fixed-Point Designer provides data types and tools for optimizing and implementing fixed-point and floating-point algorithms on embedded hardware. As mfilt.cicinterp uses fixed-point arithmetic, you can download the Fixed-Point Designer from the given link.

Correct. Can the book be updated to reflect this requirement?
