Saelig Introduces SD Bus Protocol Tracer

Pittsford, NY, USA:   Saelig Company, Inc. (Saelig) (www.saelig.com) has introduced the SDDL1000™ SD Bus Protocol Tracer, which allows design engineers working with SD and SDIO technology to capture, decode and analyze bus states, command and response tokens, and to measure SD bus performance.  Designed for engineers working on SD- and SDIO-related projects, the SDDL1000 provides time-saving features such as automatic timing violation analysis and unlimited buffer size with continuous sampling, shortening the time needed to identify and resolve bus errors. SDDL1000 also provides sufficient debug information in real time without the need to set complex trigger events. SD bus traffic prior to the error points is clearly displayed to help quickly identify problems. Debug output is displayed in a straightforward but detailed format, providing extensive information even for users less familiar with SD/SDIO/MMC specifications.

Powered from a host PC’s USB2.0 port, the SDDL1000 is only 5”x 3” x 1”, making it a highly portable device which can also be connected to a logic analyzer or oscilloscope to extend its capabilities.  SD samples are streamed directly to the host PC and stored on the hard-drive. The maximum capture capabilities are only limited by the host PC hard-drive space.

SDDL1000 offers automatic protocol timing and violation detection for SD /SDIO V3.0, real-time SD bus tracing, and advanced triggering to synchronize with digital oscilloscopes or logic analyzers for further detailed signal analysis. Data export functions include continuous capture for unlimited SD trace acquisition in SD/SDHC/SDXC/SDIO/SPI 1-bit & 4-bit modes. The SDDL1000 provides MMC support, SDIO Interrupt detection, CRC7/CRC16 verification and error detection, full bus decoding, and raw data mode.

The application software and GUI provided are Java-based and therefore instantly portable across all major PC operating systems.  A number of different test 'pods' are available to simplify connection to the device under test (e.g.  SD card, Mini and Micro SD or probe type in-circuit connection). Both raw data and command/response decode mode data are available. The SDDL1000 monitors the content of the SD command/response to extract information about SD/SDIO/MMC specification used, data bus width, etc., decoding SD traffic according to the specification detected.  The ASD Tracer offers a simplified view of SD/SDIO commands (command ID, argument) to allow fast browsing. Every SD/SDIO command/data block can be expanded to detailed view offering argument detailed description. 

Integration with the USBscope50, a thumb-drive-sized oscilloscope adapter, provides additional waveform analysis capabilities.
