Configuration Schemes

Stratix Device Handbook, Volume 2
Restart Configuration on Frame Error option is not turned on, the Stratix
or Stratix GX devices drive nSTATUS low until they are reset with a low
pulse on nCONFIG.
You can also cascade several EPC2/EPC1 configuration devices to
configure multiple Stratix and Stratix GX devices. When all data from the
first configuration device is sent, it drives nCASC low, which in turn
drives nCS on the subsequent configuration device. Because a
configuration device requires less than one clock cycle to activate a
subsequent configuration device, the data stream is uninterrupted.

You can use a single configuration chain to configure multiple Stratix and
Stratix GX devices. In this scheme, the nCEO pin of the first device is
connected to the nCE pin of the second device in the chain. If there are
additional devices, connect the nCE pin of the next device to the nCEO pin
of the previous device. To configure properly, all of the device
CONF_DONE and nSTATUS pins must be tied together.
