Check Trigonometric Function blocks in a model that use the look up table (LUT) based approximation method


This check displays a warning if your Simulink® model contains Trigonometric Function blocks such as sin, cos, sincos, atan2, and cos+jsin that use the approximation method as Lookup.

This check requires Simulink and HDL Coder™.

Results and Recommended Actions

To fix this warning for sin, cos, sincos, and cos+jsin blocks that have the LUT-based approximation method, use Sine HDL Optimized or Cosine HDL Optimized blocks instead.

Capabilities and Limitations

  • Provides the list of the unsupported Trigonometric Function blocks that have the LUT-based approximation method in your Simulink model.

  • HDL code generation is not supported for the atan2 block in the LUT-based approximation method.
