Passive Serial Configuration
10–25
You can program a serial configuration device in-system by an external
microprocessor using SRunner. SRunner is a software driver developed for embedded
serial configuration device programming, which can be easily customized to fit in
different embedded systems. SRunner is able to read raw programming data (.rpd)
and write to serial configuration devices. The serial configuration device
programming time using SRunner is comparable to the programming time with the
Quartus II software.
f For more information about SRunner, refer to AN 418: SRunner: An Embedded Solution
for Serial Configuration Device Programming and the source code on the Altera website
at www.altera.com.

Serial Configuration Devices (EPCS1, EPCS4, EPCS16, EPCS64, and EPCS128) Data Sheet
chapter in volume 2 of the Configuration Handbook.
Guidelines for Connecting Serial Configuration Devices on an AS Interface
For single- and multi-device AS configurations, the board trace length and loading
between the supported serial configuration device and the Stratix IV device family
must follow the recommendations listed in Table 10–6.

Passive Serial Configuration
You can program a PS configuration for Stratix IV devices using an intelligent host,
such as a MAX II device or microprocessor with flash memory, or a download cable.
In the PS scheme, an external host (a MAX II device, embedded processor, or host PC)
controls configuration. Configuration data is clocked into the target Stratix IV device
using the DATA0 pin at each rising edge of DCLK.
1 The Stratix IV decompression and design security features are fully available when
configuring your Stratix IV device using PS mode.
