PGY-SSM SD / SD / eMMC协议分析仪是多功能的协议分析仪,主要用来捕捉测试主机和内存之间的通信协议。PGY-SSM协议分析器支持SD,SDIO和 EMMC,数据速率高达200MHz DDR模式。PGY-SSM是业界第一个eMMC协议分析仪,支持版本4.41,4.51,5和5.1规格。独创的有源探头具有最小电气负载测试设备(DUT)和允许协议数据采集不影响被测设备的性能。另一特点是PGY-SSM协议分析仪可以连续从PGY-SSM协议分析仪主机系统的运行接口抓取协议数据流(使用USB3.0或千兆以太网接口)。全面的协议数据,指令译码单元,实时误差分析能够有效验证SD/SDIO / eMMC主机和设备之间通信。

PGY-SSM协议分析仪可以验证工程师测试和调试SD设计,通过触发命令,响应SDIO和eMMC,数据或CRC错误。它还提供了瞬时的命令,响应,CID解碼,CSD和Ext CSD寄存器。分析功能提供了易于分析的图形表示的命令,响应,数据和频率的操作,能持续监测。

Setup

prod-emmc-2.png

PGY_SSM Protocol Analyser works on the principle of fat-pipe analysis where the analyser probes are connected on the interface bus between host and device[memory] of the unit under test. It captures all transactions that are going on between the host/device and does real time analysis for errors + a detailed analysis on the captured data which is made available through UI running on a host system. Captured data is stored in the hard disk of the system running UI, enabling a long capture [expect to have enough free space in the hard disk]. PGY-SSM Protoocol Analyzer interfaces to host using USB3.0 [Super Speed] and GbE. PGY-SSM analyser & UI software runs in the host machine. PGY-SSM protocol analyzer also has the capability to capture boot data for eMMC.

Probing
PGY-SSM Protocol An1lyzer has active probe, which provides very flexible probing with minimum electrical loading of DUT. This is specifically designed keeping to address challenges in probing eMMC/SD/SDIO signals. Probe supports 200MHz DDR bandwidth so that eMMC/SD/SDIO signals can be captured without any error. Probes has a flying probe lead set with berg post connector and solder able probe tips make it very convenient to connect to DUT.

Comprehensive Protocol Analysis
PGY–SSM Software provides the industry’s best protocol analysis capabilities. A simple-to-use interface reduces the complexities and time for protocol debug. Time stamped view of decode listing provides a complete view of protocol activities between host and device. By clicking on selection prompts, the user can get the decode of arguments, CSD, CID registers, data activities and more [detailed view]

Protocol Data Capture and Trigger
PGY-SSM Protocol Analyzer has powerful protocol aware trigger capabilities allows capture protocol events at specific events. PGY-SSM supports simple and advanced trigger capabilities. PGY-SSM can trigger specific command, response, CRC error condition. Advanced trigger capabilities allows sequential trigger condition to capture protocol data after a sequence of events. In Auto mode, data is captured on pressing ttle RUN Button.

Protocol data capture duration is controlled by manual stop or setting the capture duration. Manual stop offers flexibility of set protocol data capture by visual activities in DUT. In time duration user set data capture in secs to 3 to 4 hours. During the capture mode, protocol data is continuously streamed to host system hard disk drive to storage.

Analytics
A) Analytics features quickly provide insight into protocol activity without going through the complete protocol activity. As ample plot is shown below:

The Analytics view is a bird’s eye view of protocol activity for the captured long duration data. It reduces analysis time by viewing plot command; response, data and frequency of operation of captured data. The user can search for specific command or response in the plot.

B) Card/Device Information provides decoding of register argument of device. Now the user no longer needs to manually decode each register value.
