AI Suite - Spatial IP outputs wrong value

Hello Altera Community

When looking at my Spatial IP in Signal Tap, I can see that it outputs a wrong value. Please help me identify where this mistakes happen.

Below is the Signal Tap result of my test: 3D903C90 - 3D9C3D87 -BD983E38

However from my golden_output_sink_port_0.txt I'm expecting this value: 3D12BC8D - 3DA43E1E - 3DABBE18

Below is the Singal Tap of my input

I'm inserting the values I got from input_vlogkw.txt from the DLA_COMPILER.


Here is a list of warnings I got from Quartus, but they are from proteced sv files that I can't acess:

Warning(16761): VHDL warning at spatial_first.vhd(146): actual for formal port "reset_reset" is neither a static name nor a globally static expression
