Configuring Stratix II & Stratix II GX DevicesA serial configuration device can be programmed in-system by anexternal microprocessor using SRunner. SRunner is a software driverdeveloped for embedded serial configuration device programming,which can be easily customized to fit in different embedded systems.SRunner is able to read a raw programming data (.rpd) file and write tothe serial configuration devices. The serial configuration deviceprogramming time using SRunner is comparable to the programmingtime with the Quartus II software.ffFor more information about SRunner, refer to SRunner: An EmbeddedSolution for EPCS Programming white paper and the source code on theAltera web site at www.altera.com.For more information on programming serial configuration devices,refer to the Serial Configuration Devices (EPCS1 & EPCS4) Data Sheet in theConfiguration Handbook.Figure 7–16 shows the timing waveform for the AS configuration schemeusing a serial configuration device.Figure 7–16.
