Hello,
I want to generate a Simscape Electrical model into HDL Fixed-point Code. I followed the tutorial that gives the following workflow:
Simscape Electrical model -> Simscape HDL Workflow Advisor -> Simulink implementation model -> HDL Coder -> HDL floating point Code
If I replace the single format of the input in the Simulink implementation model by a fixed-point format, the compilation failed with many errors around the Multiply Matrix block and the format of the matrices created by Simscape HDL Workflow Advisor.
Is this workflow compatible with fixed-point HDL Code generation ?

This workflow currently supports double, single and in future half precision formats.
The workflow currently does not yet support fixed-point due to high dynamic range and precision requirements of state space matrices and HIL models.
See related documentation about this topic under Use Larger Floating-Point Precision
web(fullfile(docroot, 'hdlcoder/ug/validate-hdl-implementation-model-and-resolve-numerical-mismatches.html#mw_c603353a-909c-4d48-a634-7b741748b4ce'))
Please contact Tech Support and share your model for additional support on fixed-point.
