Agilex 3 GTS PCIe IP missing

I plan a new design using PCIe 3 and LPDDR4 using Agilex3. I already have a prototype project using an existing Cyclone 5 board, and it worked just fine. I tried to move to Agilex3 (Quartus Prime P...

I installed back 25.1 and I was able to create SSGDMA instance.

But I was curious about changes and made a diff between 25.1 and 25.1.1

Among some technical changes, "intel_ssgdma_hw.tcl" (25.1.1) contains:

- set_module_property SUPPORTED_DEVICE_FAMILIES {"Agilex 5" "Agilex 3"}

this sounds nice :), but how about this ???

- # ssGDMA Deprecation Warning
- send_message warning "The sSGDMA IP is not recommended for new projects and is subject to removal in a future release. mSGDMA IP is the recommended replacement for SoC mode. GTS AXI MCDMA IP is the recommended replacement for PCIe mode."

I am confused again...

Regards,
Gabriel

    Hi @GabrielC ,

    In future, We wont support sSGDMA, and totally disappear in Quartus IP catalog
    BUT for long term development, I would suggest to check on MSGDMA / MCDMA for Agilex 5.
    Reason is due to MSGDMA is more modular, configurable, efficient, and better supported for current and future FPGA designs. This change ensures better performance, easier integration, and ongoing support, making it a clear upgrade for most applications.
