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.

1 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.

f For more information about the JRunner software driver, refer to AN 414: JRunner

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.
