"resource profile" inconsistent

Hi, while reviewing implementation results I need to analyse resource counts. Vivado HLS offers a way to see resources per module, however this is inconsistennt or I do not understand the meanings.

I concentrate on DSP counts, sometime there is 0 in the "resource profile" table while the corresponding "module hirarchy" entry is some number. Sometimes the numbers do not match.

For BRAM, FF, etc. numbers seems to be more but not complete concistent.

 

resource profile.tif

Any idea?

Ric.

Re: "resource profile" inconsistent

Hi, I just tested HLS 2015.4 which is showing the same inconsistensies.
Is there something wrong in the assumtion that the numbers of the function total row should be equal to the numbers of the function hierarchy list?
What numbers can I count on to evaluate the ressource usage of the individual functions?

Thanks, Ric.
