Strange behavior of Quartus Fitter and how to get more information

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
