There are several Arria 10 FPGAs in my project,and four FPGAs use the same design, i want to program these FPGAs with single JTAG chain.Serial program wil take plenty of time ,is it possible to progam these four FPGAs at the same time?
If the bitstream is the same then you can programmed all the FPGA at the same time through flash. JTAG will not support it.
