The serial configuration devices are designed to configure the Cyclone series and all
device families in the Stratix series except the Stratix device family. It cannot configure
other existing Altera FPGA device families.

You can access the unused memory locations of the serial configuration device to store
or retrieve data through the Nios processor and SOPC Builder. SOPC Builder is an
Altera tool for creating bus-based (especially microprocessor-based) systems in Altera
devices. SOPC Builder assembles library components such as processors and
memories into custom microprocessor systems.
SOPC Builder includes the EPCS device controller core, which is an interface core
specifically designed to work with the serial configuration device. With this core, you
can create a system with a Nios embedded processor that allows software access to
any memory location within the serial configuration device.
