circuit is similar to the FPP configuration circuit for a single device, except the
Arria II GX devices are cascaded for multi-device configuration.
After the first device completes configuration in a multi-device configuration chain,
its nCEO pin drives low to activate the nCE pin of the second device, which prompts
the second device to begin configuration. The second device in the chain begins
configuration in one clock cycle; therefore, the transfer of data destinations is
transparent to the MAX II device or microprocessor. All other configuration pins
(nCONFIG, nSTATUS, DCLK, DATA[7..0], and CONF_DONE) are connected to every
device in the chain. The configuration signals may require buffering to ensure signal
integrity and prevent clock skew problems. Ensure that the DCLK and DATA lines are
buffered for every fourth device. Because all device CONF_DONE pins are tied together,
all devices initialize and enter user mode at the same time.
All nSTATUS and CONF_DONE pins are tied together and if any device detects an error,
configuration stops for the entire chain and you must reconfigure the entire chain. For
example, if the first device flags an error on nSTATUS, it resets the chain by pulling its
nSTATUS pin low. This behavior is similar to a single device detecting an error.
If a system has multiple devices that contain the same configuration data, tie all
device nCE inputs to GND and leave the nCEO pins floating. All other configuration
pins (nCONFIG, nSTATUS, DCLK, DATA[7..0], and CONF_DONE) are connected to
every device in the chain. Configuration signals may require buffering to ensure
signal integrity and prevent clock skew problems. Ensure that the DCLK and DATA
lines are buffered for every fourth device. Devices must be the same density and
package. All devices start and complete configuration at the same time.
