does it means that it is possible to done the 1680 cores thing on the Arty board? if can't, what made the Xilinx board more suitable to implement the 1680-cores on it ?
The Xilinx board has a ton of logic slices to run the extra cores. It's like chips having more transistors able to do more stuff. The Arty is too small to hold the full design. Might run slower, too, if on a older, process node than the Xilinx FPGA.
Both of them are Xilinx boards. One of them is just a really, really high end xilinx board, so it basically has enough programmable fabric to hold 1680 cores. The other is cheap and can't hold as many cores.
