# MATLAB: Do I receive a “parameter out of range” error when I run the model that contains a filter block realized by FDATool

Why do I receive a "parameter out of range" error when I run my model that contains a Filter block realized by the Filter Design Tool in Filter Design Toolbox 2.2 (R13.0.1)?
1. I designed a low pass filter using FDATool
2. I enabled quantization for the filter
3. I optimized the filter to prevent overlow
4. I realized the filter in a Simulink model
When I run the model, I get an error message similar to the following, saying it saturated at the second stage of the filter:
 Parameter is outside the range of the fixed point data type; it has been saturated to its maximum limit in 'xilinx_1st/SMPTE_1.3Mq/s(2)'
