FINN Hardware Resource Usage in Pynq-Z2

[Ba1tu3han]

Hello,

I have quantized and trained the CNV model which is from Brevitas Github repo. Then, I compiled it by FINN by following CNV end-to-end example and run it in Pynq-Z2.

I would like to learn how much hardware resource of just the FPGA it uses. Do you recommend a guide or a notebook?

Thank you,

Bests,
Batuhan

Hi,

you can inspect the design manually using the Vivado GUI or use the post_synth_res FINN analysis pass:

finn/src/finn/analysis/fpgadataflow/post_synth_res.py

Line 38 in 766e9fb

def post_synth_res(model, override_synth_report_filename=None):

If you use the FINN builder, it will also copy the Vivado utilization report to "report/post_synth_resources.xml" in your output directory.

Hello Felix,

Thank you for your reply.

I will use both of them. Then I will decide to which one is more suitable for my case.

Could you provide me a starting point for Vivado GUI for hardware utilization?

Hi @Ba1tu3han,

Please refer for this to the official documentation about Vivado, e.g. here: https://docs.amd.com/r/en-US/ug906-vivado-design-analysis/Report-Utilization
There are also useful videos on how to navigate in the Vivado GUI that you can find online.
