FINN examples on AUP-ZU3

Updated the finn-examples build flow for the AUP-ZU3 board and added 64-bit buffer support to the driver script.

Note

To build some of the bnn-pynq examples, the timeout limits of the set-fifo-depths simulation must be extended in the code (see issue #1435). The rtlsim liveness threshold may also need to be adjusted; this can be done by setting the LIVENESS_THRESHOLD env var.

Tool Version Requirements

• FINN commit 3a0cd1c ¹
• PYNQ v3.1
• Vivado 2024.1

Footnotes

1. Needed because: supports 64-bit buffers introduced in PYNQ v3.1 and has AUP-ZU3 board integration in FINN ↩

2. Model too large to be built for the AUP-ZU3 ↩ ↩²

3. Dataset too large to run on the AUP-ZU3 ↩
