File Support

The Quartus II design 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

designers can customize to fit in different embedded systems. The

SRunner can read a Raw Programming Data file (.rpd) and write to the

serial configuration devices. The programming time is comparable to the

Quartus II software programming time.

For more information about SRunner, see the SRunner: An Embedded

Solution for Serial Configuration Device Programming White Paper and the

source code on the Altera web site (www.altera.com).

Serial configuration devices can be programmed using the APU with the

appropriate programming adapter (PLMSEPC-8 or PLMSEPC-16) via the

Quartus II software, USB Blaster, 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 or ByteBlaster II download cable, the cable pulls

nCONFIG

low to reset the FPGA and overrides the 10-k

Ωpull-down resistor on the

FPGA’s

nCE pin (see Figure 4–2). The download cable then uses the four

interface pins (

DATA, nCS, ASDI, and DCLK) to program the serial

configuration device. Once 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.
