MCIO to PCIe Host Adapter for Agilex 7 M-series Dev Kit

Hello,

I need help to choose the right MCIO cables and MCIO-PCIe Gen5 adapter to connect an Agilex 7 M-series dev kit to a host over CXL (Compute Express Link). The host is a Lenovo workstation featuring 2x Intel Xeon Gold 6416H (2x18-core, 45MB Cache, up to 4.20GHz) and 4 PCIe 5.0 slots.

Is there a recommended set of MCIO cables and MCIO-PCIe adapters that have been tested and with Agilex 7 M-series dev kit?

In theory, I should be able to use this MCIO-PCIe adapter together with two MCIO SFF-TA-1016 8i cables, but could find no cross reference to supported hosts and FPGA devices.

Thank you for your help,

Denisa Constantinescu

    Hi Denisa,

    The Agilex 7 I-series Dev Kit (2xR-Tile+1xF-Tile) MCIO connector can work with Amphenol cable P/N: HMC74-1492 in a PCIe Gen5 test. This is the only info I have so far. Hope this helps.

    Regards,

    Rong

      Hi Jzone315,

      We tried the mcio-PCIe adapter but could not make the FPGA PCIe device visible from the host side. Unfortunately, Intel/Altera does not provide a PCIe design example for the Agile 7-M series, so we adapted the one available for the I series. Said this, I am not sure if the problem is the cables, the adaptor or the PCIe IP design.

      Dear Altera/Intel Support,


      According to the documentation ( https://www.intel.com/content/www/us/en/products/details/fpga/development-kits/agilex/agm039.html), a PCIe 4.0 Design example is provided, but I could not possibly locate it. Is there any chance there will be a reference design for using the PCIe on the Agile 7-M series dev kit? If not, is this still the official channel to get post-purchase support to help Altera FPGA users get the basics working?

      Thanks,

      Denisa

        Hi Denisa：

        Yes，we tried this mcio-pcie adapter too, also failed to work, we are pretty sure that it is the problem of this adapter, but intel does not provide this adapter, nor does it provide a link to buy

    Hi All,

    Have you got any updates or progress regarding the PCIe access for Agilex 7 M-series? I am starting work with that. Thank you.
