Upgrading CycloneIV PCIe with Avalon-ST interface to 20.1

Hi,

I'm trying to upgrade my older designs to 20.1 so I only need a single version of Quartus installed (also, installing 16.1 has become a bit more difficult, as noninteractive installs no longer work).

One of my designs has a PCIe interface on a CycloneIV GX, with several hand-written components that attach to the Avalon-ST interface, but it seems the IP block no longer exists in the library and no upgrade path exists. The "Release Notes" link suggests that it was discontinued, but the link does not work, so I can't tell when exactly or what would replace it.

Is there still a way to get TLPs through an Avalon-ST interface in 20.1?

    Hi,


    Starting from v19.1, the PCIe IP is supported in V-series devices only. You may use v18.1 and earlier if you would like to use in Cyclone IV.


    Thanks

    Best regards,
