Can we modify a PCIe AXI Master IP that is unavailable to make it work?

Hi there,

I have been using MATLAB PCIe as a AXI master for a long time on the VCU118 board. Now we got the newer and bigger board VCU129-G. Unfortunately, in this transition, the "PCIe MATLAB as AXI Master" IP is becoming unavailable. This is shocking for me since now I lose all my designs that I have developed so far. I would really appreciate if someone can provide a working solution in this transition. Otherwise the new expensive board becomes useless for me. Thanks.

I know MATLAB doesn't list ,VCU129-G board as a supported part but I am here just to find a possible workaround, even if it's an alpha or temporary solution. Please help me out. Thanks.
