Hi abaxor,


Sorry that I may not fully understand your request regarding the conversion as you mentioned. Can share with me more details on your work?

There is some tutorial/design example in the HLS directory that may help with your understanding.

<quartus_installdir>//hls\examples\tutorials\ac_datatypes\ac_fixed_constructor

Refer to this link for more info:

Thanks.
