Configuration Features
Configuring Cyclone III Device Family with the JRunner Software Driver
The JRunner software driver allows you to configure Cyclone III device family
through the ByteBlaster II or ByteBlasterMV cables in JTAG mode. The supported
programming input file is in .rbf format. The JRunner software driver also requires a
Chain Description File (.cdf) generated by the Quartus II software. The JRunner
software driver is targeted for embedded JTAG configuration. The source code is
developed for the Windows NT operating system (OS). You can customize the code to
make it run on your embedded platform.

The .rbf used by the JRunner software driver cannot be a compressed .rbf because the
JRunner software driver uses JTAG-based configuration. During JTAG-based
configuration, the real-time decompression feature is not available.

Software Driver: An Embedded Solution for PLD JTAG Configuration and the source files
on the Altera website at (www.altera.com).
Combining JTAG and AS Configuration Schemes
You can combine the AS configuration scheme with the JTAG-based configuration
(Figure 9–29). This setup uses two 10-pin download cable headers on the board. One
download cable is used in JTAG mode to configure the Cyclone III device family
directly using the JTAG interface. The other download cable is used in AS mode to
program the serial configuration device in-system using the AS programming
interface. The MSEL[3..0]pins must be set to select AS configuration mode (Table 9–7
on page 9–11). If you try configuring the device using both schemes simultaneously,
the JTAG configuration takes precedence and the AS configuration terminates.
