if-else equivalent block for hdl code generation

hello,I want to use if-else block in my simulink model to generate hdl code but when i am using if-else simulink block and trying to use hdl coder then it is showing an error that,"if-else block is unsupported for hdl code generation",then i tried to use matlab function block and within matlab function i have written logic of if-else then it is showing an error that"MATLAB function block is unsupported for hdl code generation while using floating data type" So plz suggest which block(hdl supported block) can be used in place of if-else simulink block.

Rewrite the MATLAB Function Block to avoid using floating point data.

actually i am using 'data-type conversion' block within my simulink model for that i have choosen native floating point data type because without this native floating point mode i am unable to get hdl code error is that."Illegal conversion to/from floating point and fixed-point in hdl_non_overlapped/Data Type Conversion. Consider selecting 'Native Floating Point' as the Floating Point IP Library to enable this conversion."

Can you share your model?

I need to see the MATLAB Function Block code.

MATLAB Function block does not yet support Native Floating Point. This is a future enhancement under consideration.

If you want to model if else equivalent in HDL coder you have to use switch block. For nested if else ,you have to Cascade switch blocks in priority order.
