Figure 11–12. Parallel Configuration Using a Microprocessor
Note to
(1)
For multi-device parallel configuration with a microprocessor, the nCEO
pin of the first Stratix or Stratix GX device is cascaded to the second
device’s nCE pin. The second device in the chain begins configuration
within one clock cycle; therefore, the transfer of data destinations is
transparent to the microprocessor. Because the CONF_DONE pins of the
devices are connected together, all devices initialize and enter user mode
at the same time.
Because the nSTATUS pins are also tied together, if any of the devices
detects an error, the entire chain halts configuration and drives nSTATUS
low. The microprocessor can then pulse nCONFIG low to restart
configuration. If the Auto-restart configuration after error option is on,
the Stratix and Stratix GX devices release nSTATUS after a reset time-out
period. The microprocessor can then reconfigure the devices once
nSTATUS is released.
using a microprocessor.
when both Stratix and Stratix GX devices are receiving the same data. In
this case, the microprocessor sends the data to both devices
simultaneously, and the devices configure simultaneously.
