TLAST Signal Not Generated in RTL Files (HLS4ML + Vitis HLS and pynq Z2)

[Kataru Siri Dhari]

Hi,
I am using Vitis HLS for my signature forgery detection project. I wrote the ML model in Python and used HLS4ML to convert it into C++ files. I then used Vitis HLS to generate RTL files.

I am planning to include DMA in my block design, so I need the TLAST signal. However, although I am using io_stream in HLS4ML (which should automatically generate the TLAST signal), it is not being generated in the RTL files.

I have attached the C++ file, and some of the header files for reference.
Has anyone faced a similar issue or knows how to ensure TLAST is included in the RTL design?
There are several other header files generated, but I’ve shared the ones I felt were most relevant.
Any help or suggestions would be appreciated.
