With SRAM-based devices, configuration data must be reloaded each
time the system initializes, or when new configuration data is needed.
Altera configuration devices store configuration data for SRAM-based
APEX II, APEX 20K, Mercury, ACEX, and FLEX devices. Table 1 lists
Altera configuration devices.
