Hi, I am studying the usage of the NPU device.

When running the "passthrough_kernel" demo in programming_examples, I find the results are different with different AIEDevice settings. If I use the default AIEDevice setting "AIEDevice.npu1_1col", it works well. However, if I set it to "AIEDevice.npu1_4col", the result will not pass the verification.

In my understanding, the setting of the AIEDevice will not impact the result. Is that a bug? Or I misunderstand some knowledge of the NPU.
Thanks!
