Document Table of Contents Using Multiple Configuration Data

To configure multiple Stratix® V devices in a chain using multiple configuration data, connect the devices to an external host as shown in the following figure.

Note: If you are using the FPP x8 configuration mode, use DATA[7..0] pins. If you are using FPP x16 configuration mode, use DATA[15..0] pins.
Note: By default, the nCEO pin is disabled in the Intel® Quartus® Prime software. For multi-device configuration chain, you must enable the nCEO pin in the Intel® Quartus® Prime software. Otherwise, device configuration could fail.
Figure 168. Multiple Device FPP Configuration Using an External Host When Both Devices Receive a Different Set of Configuration Data

When a device completes configuration, its nCEO pin is released low to activate the nCE pin of the next device in the chain. Configuration automatically begins for the second device in one clock cycle.
