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,


Per my understanding there are a few reports available, Quartus/HLS estimated resource utilization summary which shows total area utilization of entire design and each component individually. What are you showing I believe is the summary of the report, perhaps zooming in will give an idea on which component are taking up the resources.


Also there are a area analysis of system report (Area Analysis > Area Analysis of System), it can be used to identify parts of the design that are having large area overhead.

Hope that clarify.


Best Wishes

    Hi @BoonBengT_Altera

    All these detailed reports are "estimated resource utilization" reports. In all this report the new architecture uses much less area than the original one. However, when implemented, the fitter fails. So, there are no useful information on this problem in those report. I need a report on the fitting process to see what's going on or any inside why the estimate said the area is reduced when the fitter said it grows.

    Thanks
