Difference between area.rpt and "kernelname".area

Hello, I have compiled an example kernel and I found the files

- area.rpt

- "kernelname".area

in the bin folder.

Does the file area.rpt shows the total amount of Hardware used (for the Kernel + BSP)?

And the file vecadd.area shows the Hardwareelements used only for this function?

In this files there is also a section called Util, can someone tell me what this stands for? (I can´t find a translation to german where this word makes sense in this context)

Exampleoutput:

LEs: 3.09659 %

FFs: 1.89328 %

RAMs: 7.7821 %

DSPs: 0 %

util: 4.68994 %

    Can you attach the files to your reply? These reports have been renamed/removed/changed numerous times in different versions of AOC and these files that you mention do not exist in kernels compiled with v16.x and above.

    I could be wrong (the version you are using is too old) but as you yourself said, the area.rpt is probably kernel + BSP while "kernel_name".area is kernel only. The "Util" field most likely shows your logic (ALM) utilization, i.e. the number of logic elements with at least one ALUT or register occupied in it.
