Description
Issue: VFS Assertion Failure with output_pktstream
Error Log: Assertion failure 'in && (in->type() == STREAM || in->type() == WINDOW || in->type() == CASC)' at .../xmcPlatformBufferWriter.cpp:70
Here is the source code to reproduce the issue:

Research direction
Start with Vitis-Tutorials/Vitis_System_Design/Feature_Tutorials/01-Vitis_Functional_Simulation/aie/GraphMultiplyByComplex/src and review kernels.cpp, kernels.h, and mySub.h, focusing on the output_pktstream reproduction. Source Vitis, then run python3 test.py from the example's python directory to confirm the assertion at xmcPlatformBufferWriter.cpp:70. Done means the supplied example runs without that assertion failure.
