Multiple FPGAs can be configured using a single enhanced configuration device in
FPP mode. In this mode, multiple Stratix series FPGAs, APEX II FPGAs, or both, are
cascaded together in a daisy chain.
After the first FPGA completes configuration, its nCEO pin asserts to activate the nCE
pin for the second FPGA, which prompts the second device to start capturing
configuration data. In this setup, the FPGAs CONF_DONE pins are tied together, and
hence all devices initialize and enter user mode simultaneously. If the enhanced
configuration device or one of the FPGAs detects an error, configuration stops (and
simultaneously restarts) for the whole chain because the nSTATUS pins are tied
together.
While Altera FPGAs can be cascaded in a configuration chain, the enhanced
configuration devices cannot be cascaded to configure larger devices or chains.
