how to properly simulate NoC in Timeloop-Accelergy?

[ywlywl6]

I have noticed that in most examples under timeloop-accelergy-exercises, the Networks section in the generated stats.txt files is consistently empty. However, there are a few exceptions across the project directory. For instance:
src\accelergy\test\tests\exercises\timeloop-accelergy-exercises\workspace\baseline_designs\example_designs\eyeriss_like\example_AlexNet_layer1_outputs\timeloop-mapper.stats.txt
In this case, the Networks field contains valid results. What confuses me is that in another simulation also targeting Eyeriss, namely
timeloop-accelergy-exercises\workspace\tutorial_exercises\01_accelergy_timeloop_2020_ispass\timeloop\06-mapper-convlayer-eyeriss,
the generated stats.txt still shows an empty Networks section.

Therefore, I would like to ask: how should the NoC be properly configured and simulated? I have tried explicitly defining LegacyNetwork or XY_NoC, but the simulations always fail to run. Moreover, no explicit error messages appear in timeloop-model.accelergy.log, leaving me unsure about the root cause of the problem.

3levelspatial.arch.yaml
I attempted to explicitly define LegacyNetwork or XY_NoC, and one of the configuration records is attached. This setup was modified from the official example workspace\tutorial_exercises\01_accelergy_timeloop_2020_ispass\timeloop\04-model-conv1d+oc-3levelspatial. In this experiment, I only added an legacy or XY NoC between the GLB and PE, while keeping all other parts unchanged. However, the simulation failed to produce the correct results.
