How to convert the Simulink project to VHDL code?

I have created a digital down converter in simulink and I want to convert it into VHDL Code.But in this I can only convert one subsytem to VHDL rest of them is getting one or another type of errors.

The errors are:

call to function cordicrotate is not supported

comment out the block

set the multitask data transfer and singletask data transfer to error on diagnostics additionaly in solver pane,set solver type to fixed-step and in the solver details-tasking and samle time options group selet 'treat each discrete rate as a separate task'

You can run the hdlsetup function on the model to set the parameters of the model to common default values for HDL code generation.

This example shows how to build a DDC for HDL code generation and may give you some insight as well.

I wantt to use the cordic processor itself and when I want to convert this block the error is coming.

error is 'call to function cordicrotate is not supported'

Implement Digital Downconverter for FPGA

This example shows how to design a digital downconverter (DDC) for radio communication applications such as LTE, and generate HDL code.

Are you implementing these modules using custom subsystems?

Can you reach tech support or share your model with the reproduction steps?
