Multiple devices can be configured by a single EPCS device. However,
serial configuration devices cannot be cascaded. Check
Table 4–1
to
ensure the programming file size of the cascaded FPGAs does not exceed
the capacity of a serial configuration device.
Figure 4–4
shows the AS
configuration scheme with multiple FPGAs in the chain. The first
Stratix II or Cyclone device is the configuration master and has its
MSEL[]
pins set to AS mode. The following FPGAs are configuration
slave devices and have their
MSEL[]
pins set to PS mode.
