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?

Hi,
If you are connecting the FPGA in the JTAG chain, then you can program all the device in the single flow but the device will be configured sequentially.

Hi JohnT,
Thanks for reply.If these FPGAs are configured sequentially, no time will be saved. I want configure 5 FPGAs parallely, since these 5 FPGAs' bitstream is the same.

Hi,
If the bitstream is the same then you can programmed all the FPGA at the same time through flash. JTAG will not support it.
