Active Serial FPGA Configuration

Altera Corporation

Configuration Handbook (Complete Two-Volume Set)

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.

Figure 3–1 shows the serial configuration device block diagram.

Accessing Memory in Serial Configuration Devices

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.

f For more information about accessing memory within the serial configuration device,

refer to the Active Serial Memory Interface Data Sheet.

Active Serial FPGA Configuration

The following Altera FPGAs support Active Serial (AS) configuration scheme with

serial configuration devices:

■

Arria series

■

Cyclone series

■

all device families in the Stratix series except the Stratix device family

1 This section is only relevant for FPGAs that support the AS configuration scheme.
