The Quartus II software provides programming support for serial configuration
devices. After selecting the serial configuration device, the Quartus II software
automatically generates the Programmer Object File (.pof) to program the device. The
software allows users to select the appropriate serial configuration device density that
most efficiently stores the configuration data for a selected FPGA.
The serial configuration device can be programmed in-system by an external
microprocessor using SRunner. SRunner is a software driver developed for embedded
serial configuration device programming that you can customize to fit in different
embedded systems. The SRunner can read .rpd files and write to the serial
configuration devices. The programming time is comparable to the Quartus II
software programming time. Note that writing and reading the .rpd file to the EPCS is
different from other data and address bytes. The LSB of .rpd bytes must be shifted out
first during the read bytes instruction and the LSB of .rpd bytes must be shifted in first
during the write bytes instruction. This is because the FPGA reads the LSB of the .rpd
data first during the configuration process.
For more information about SRunner, refer to
for Serial Configuration Device Programming User Guide
Altera website (www.altera.com).
Serial configuration devices can be programmed using the APU with the appropriate
programming adapter (PLMSEPC-8) via the Quartus II software, USB Blaster,
EthernetBlaster, or the ByteBlaster II download cable via the Quartus II software. In
addition, many third-party programmers, such as BP Microsystems and System
General, offer programming hardware that supports serial configuration devices.
During in-system programming of a serial configuration device via the USB Blaster,
EthernetBlaster, or ByteBlaster II download cable, the cable pulls nCONFIG low to
reset the FPGA and overrides the 10-k pull-down resistor on the FPGA’s nCE pin
(refer to
ASDI, and DCLK) to program the serial configuration device. When the programming
is complete, the download cable releases the serial configuration device’s four
interface pins and the FPGA’s nCE pin, and pulses nCONFIG to start configuration.
The FPGA can program the serial configuration device in-system using the JTAG
interface with the Serial FlashLoader. This solution allows you to indirectly program
the serial configuration device using the same JTAG interface that is used to configure
the FPGA.
