Document Table of Contents Using Multiple Configuration Data

To configure multiple Arria® 10 devices in a chain using multiple configuration data, connect the devices to an EPCQ-L device, as shown in the following figure.

Figure 135. Multiple Device AS Configuration When Both Devices in the Chain Receive Different Sets of Configuration Data

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

Set the master device MSEL pin setting to AS scheme and the slave device MSEL pin setting to PS scheme. If your slave device (for example, 28 nm devices such as Stratix® V, Arria® V, and Cyclone® V) supports configuration voltage (VCCPGM) up to 3.0 V, Intel® recommends that you send the VCCPGM at 1.8 V so that a voltage translator is not needed.
