When using the 25G Ethernet Intel® Arria® 10 FPGA IP the example design section incorrectly shows the Intel® Arria® 10 GX Transceiver Signal Integrity Development Kit as an available option in the Target Development Kit:Select board parameter. This is mistake as the generated example design targets the Intel® Arria® 10 GT family only.
The Intel® Arria® 10 GX family does not supprot the required 25G transceivers.
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 20.4.
