There is a builder config setting to split large FIFOs into smaller ones for this scenario: https://github.com/Xilinx/finn/blob/9f0fad5717ae652eaa324583e957161890964555/src/finn/builder/build_dataflow_config.py#L268
However, I doubt that you should need FIFOs this deep for one of these small models. Do you let FINN determine the FIFO sizing automatically in "step_set_fifo_depths"?
In my custom configuration file, I don't determine anything about FIFO. Is it about being a large number of not being power of two? Should I assign them in the config file? I want to everything in compiling step as automatic.
This is my building steps.
The model is original CNV model and trained it by Brevitas.
Custom Config File: custom_folding_config_2W1A.json

Quick summary
I trained a model with 1W1A and 2W1A quantization then I compiled 1W1A for Pynq-Z2 by FINN however I have encountered a FIFO error for 2W1A. Additionally, I use seperated custom configuration files.
Could you help me about how to set or check FIFO ?
