Dear All,
I am trying to use Fixed-Point Tool to convert my model in Simulink from a double precision to fixed point precision in order to genenrate HDL design. After applying proposed data types I simulate my model with proposed types and I got overflow at the output of the adders and multipliers.
My question is: is there any tool/function/command within Fixed-Point Tool which would 'fix' those blocks with an overflow? How to do it manually? Is there any tutorial for the latest 2019a version of the Fixed-Point tool?
Kind rergards,
F.

Hi @Filip
To diagnose the overflow errors in Fixed Point Tool you can use FixptConstOverflowMsg which was introduced since R2009b.
You can read further from here: https://www.mathworks.com/help/simulink/gui/detectoverflow.html
