Check
ID:com.mathworks.HDL.ModelAdvisor.runUnsupportedLUTTrigFunChecks
Check for Trigonometric Function blocks in a model that use an approximation method based on lookup tables (LUT).
Description
This check displays a warning if your Simulink® model contains Trigonometric Function blocks that have
Function set to atan2 and
Approximation method set to
Lookup.
Available with Simulink, HDL Coder™, Fixed-Point Designer™, and MATLAB® Coder™.
Results and Recommended Actions
To fix this warning, set Approximation method to
CORDIC for Trigonometric Function
blocks that have Function set to
atan2.
Capabilities and Limitations
Runs on library models.
Analyzes content in all masked subsystems.
Allows exclusions of blocks and charts.
Does not analyze the content of library linked blocks.
