Hi,
in the compilation report, I don't understand how the number of used combinational gates plays against ALMs.
Originally I had a function that used several +/* on float64 and compiling that (...

Super ContributorHello,
I wonder where you see "used combinational gates" in a compilation report. Which device family, Quartus version?

StefanoCQuartus Prime Pro 22.2, device family Cyclone 10 GX, see the attached screenshots. I noticed that adding floating point multiplications in my vhdl component reflects in increasing the number of "used combinational gates", but I don't know why in the overall Logic Utilization I see just 1/80,330 <1%.
On the contrary rewriting the vhdl component into a vhdl function, would bump the Logic Utilization from 1/80,330 <1% to something like 50%.
