Strange behavior of Quartus Fitter and how to get more information

Hi, I'm designing an accelerator for DTW computation using oneAPI and Stratix 10 at the board BittWare 520N-MX Gen3x16. I have a kernel (it's actually several different kernels connected with pipes...

Hi @JavierHormigo,


Form the screenshot that you have provided yes it is empty, and that make sense as suspecting the reason to that is the failure in the hardware compilation. (which will generate the quartus fitter data)


Would suggest here to use the 12 kernel as a baseline (as it is the only successfully compiled one) and look at the report from both oneAPI and quartus estimation and see if there is any optimization left we can do in the design to make less resource needed.

Hope that clarify.


Best Wishes

Hi @BoonBengT_Altera,

I did what you suggested and that lead us to my first question: Using the 12 kernel as a baseline, the estimation report said the new version uses around 40% fewer resources. However, the fitter fails to implement the hardware because of a lack of enough LABs. How is this possible? How could I get more information about the fitter process?

Thanks,

JAvier
