Different LUT utilization in the System Diagram and Utilization tabs

Open m-kru opened this issue 2 years ago • 2 comments

I have compiled and linked some custom kernel. When I view the report, using Vitis Analyzer, I can see different utilization information in the System Diagram tab and in the Utilization tab.

The first one presents that the LUT utilization is 4.85%. However, the second one presents it is 16.25%. Other resources also have different values in both tabs, however the differences are not so big.

Is it a bug, or am I missing something?

Hi @m-kru , on your second screenshot, the post route utilization is the device utilization. It includes kernels and the platform resources.

So the kernel resource utilization is less than 5%, but approximately 11% is taken by extra things such as AXI infrastrucute etc.?
