Can I connect multiple EPCQL devices in cascade for an Arria 10 / Stratix 10 device while programming in ASx4 configuration mode ?


Yes, the EPCQL configuration devices can be connected in a cascaded fashion to store larger bitstreams in ASx4 configuration scheme for Arria® 10 and Startix® 10 device families.

While using the .jic file flow, when the configuration devices are in cascade, the default SFL IP Core in Quartus® Programmer will see the cascaded flash devices as a single device with summed up capacity as a whole. As a result only a single .jic file is created which spans to program all devices in the sequence.

While using the .rpd file flow with 3rd party programming tools, multiple RPD files will be generated according to the configuration device’s capacity. Each of the configuration device in the sequence will expect to be programmed with it’s respective individual .rpd file.
