How to generate a fixed point HDL Code from a Simscape Electrical model ?

Hello,

I want to generate the HDL Code from a Simscape Electrical model. Here is what I am doing:

1. I run the sschdladvisor tool to generate the Simulink implementation model. This generated Simulink implementation model is in single format. The matrices of the state-space model are 3D matrices.
2. I run the HDL Workflow Advisor on the generated Simulink implementation model. The generated HDL Code is too big to fit into a Xilinx Kintex ultrascale+ XCKU15P.
3. I adapted the generated Simulink implementation model from single to fixed point format.
4. I run the HDL Workflow Advisor on the fixed point Simulink implementation model, but it returns the error that the 3D matrices are not allowed:

Could you please help me to adapt the generated Simulink implementation model into a fixed point format that is compatible with the HDL Code generation ?

Thank you for you help

Typically fixed-point conversion leads significant numerical challenges on this model due to large dynamic ranges of the state-space matrices involved during Simscape to HDL FPGA translation. Hence only floating-point workflow is currently enabled.

Can you share your usecase simscape model and manually converted fixed-point model? we would like to evaluate the validation strategy and provide further guidance on potential options.

Thanks
