    To recreate the issue you will need the FPGA AI Suite version 2026.1.1-quartus.

     

    Transfer the the bin and xml files called "fpga_model_spatial_1" to the docker env.

    Then execute the following command:

     

    dla_create_ip \

    --ip-dir ./ip_repo \

    --flow create-ip \

    --arch /opt/altera/fpga_ai_suite/ubuntu/dla/example_architectures/AGX5_Simple_Spatial.arch \

    --model ./fpga_model_spatial_1.xml

     

     

    Now in Quartus Prime Pro 26.1, create a now project called "spatial_first". Targeting Agilex5 device A5EB013BB23BE4SR1. Then move the ip_repo folder next to the quartus folder.

     

    Now you will need 4 files,

    The Top entity called "spatial_first.vhd"

    The QSF config called "spatial_first.qsf"

    The system containing the AI model from the ip repo "spatial.qsys"

    The signaltaptest.stp to see the signal tap output

     

    The files I have uploaded here on my github, I can also upload the entire project if you will accept that.
