When Arria® 10 is the master device, multi-device configuration will fail if the slave device is the FPGA family device older than Arria® 10. Impacted multi-device configuration scheme:
- Active Serial
- Passive Serial
- Fast Passive Parallel (x8, x16, x32)
Arria® 10 device contains certain padding words at the end of its bitstream. In multi-device configuration, the Arria® 10 device nCEO is asserted before this padding word. When an older FPGA slave device receives this padding word, it causes the slave device to kick start configuration prematurely.
This problem is fixed starting with the Intel® Quartus® Prime Pro and Standard Edition Software version 17.1. Design recompilation is not required, you only need to regenerate the programming file, such as POF/JIC/RBF files in Intel® Quartus® Prime Pro and Standard Edition Software version 17.1.
