Configuration Schemes

Table 2–7

lists the required signals for the flash memory. Flash signals are

routed from the Spansion flash device to the MAX II device. The required
signals are then routed from the MAX II device to the Arria GX device
(see

Figure 2–4

). Signal directions are relative to the MAX II device as far

as direction and signaling standard.

Table 2–8

shows configuration file sizes for the Arria GX device.
