Artix-7 and Zynq 7015 devices have the same GTP transceivers. So, it is fine to generate the core targeting Artix-7 GTP transceivers and change the target device for the generated design to Zynq 7015 device.
Please follow the steps below to target Aurora 8B10B core to Zynq 7015 device:
Aurora 8B10B core can be synthesized now to target Zynq 7015 device.
