An ASCII text file (with the extension .sbd) that contains configuration information, such as memory region definitions, for the Excalibur^™ embedded processor stripe of an ARM^®-based Excalibur device. You or the Software Builder can use the SBD File to generate flash programming files, passive programming files, and Simulator initialization files.

You can generate the SBD File with the ARM-based Excalibur MegaWizard^® Plug-In, which is available from the MegaWizard Plug-In Manager (Tools menu). A Quartus^® II project has only one SBD File.

Altera^® recommends using the ARM-based Excalibur MegaWizard Plug-In to modify the SBD File, rather than editing the SBD File manually.
