Question on large-scale simulation

[ZiFengZhao]

Hi,
Thanks for the great work on ONNXim! It's very helpful for multi-core NPU arch. DSE.
I have a couple of questions regarding scaling and NoC configurations:

1. Can ONNXim simulate larger systems, e.g., a 16/32-core NPU? If so, how should I set up and run such simulations? I tried modifing the configuration file (configs/systolic_ws_128x128_c4_booksim2_tpuv4.json) by setting 16 cores and updating icnt_config_path to fly_c64_m8.icnt. Then I ran the following cmd:
   ./build/bin/Simulator --config ./configs/exp_systolic_ws_128x128_c16_booksim2.json --model ./example/models_list.json
   but encountered the following error: Floating point exception (core dumped). Do you know what might be causing this?

2. Is it possible to configure the NoC as a Booksim mesh topology?
   Best regards
