Thanks Neo for mentioning the required Xillinx license
I am still looking at layouts/schematic/pictures and the Z-Pack hm-zd connector on the this EBZ evaluation board seems to mate with the JESD204x connector of the DPG3 and all FMC interposer cards have the LVDS/LVCMOS connector.
Just thought of asking for a confirmation from you that the interposer can be used to conform the convert the hm-zd to FMC
