eMMC (4.41, 4.51 and 5.0) and SD (UHS-I) Electrical Validation and Protocol Decode Software

eMMC and SD Electrical Validation and Protocol Decode Software offers electrical measurements compliance testing and protocol decoding as specified in eMMC and SD specification. PGY-eMMC and SD Electrical validation and Protocol decode software runs in Tektronix Oscilloscope provides electrical measurements and protocol decode at click of button. This allows engineers quickly check for eMMC and SD compliance and flexibility to debug the failure. In addition to this engineer can decode the command and response of eMMC and SD debug the communication. PGY-eMMC and SD takes advantage of digital channels of MSO and provides the decoding of eMMC and SD data lines.

eMMC (4.41, 4.51 and 5.0) and SD (UHS-I) Electrical Validation and Protocol Decode Software

The innovative active probe has minimum electrical loading on the device under test (DUT) and allows protocol data capture without affecting the performance of the DUT. In an industry-first feature, PGY-SSM protocol analyzer allows continuous streaming of protocol data from PGY-SSM Protocol Analyzer to the host system (using USB3.0 or GbE interface) running the UI. Comprehensive decoding of protocol data, command units, and real time error analysis enable effective verification of communication of SD/SDIO/eMMC host and device.

PGY-SSM Protocol Analyzer enables design and verification engineers to test and debug SD, SDIO and eMMC by triggering on command, response, data or CRC errors. It also provides instantaneous decoding of Command, Response, CID, CSD and Ext CSD registers. The Analytics feature offers easy to analyse graphical representation of command, response, data and frequency of operation for the acquired duration.

Features
The product features are as follows:

  • Continuous monitoring of protocol data for long time to capture elusive events (more than 30GB data capture)
  • Analysis of captured data per standards for protocol integrity, count of data bursts, CMD CRC errors, Response CRC errors, Data CRC errors, Timing Values and Reserved commands
  • Hardware-based protocol-aware trigger capability in real time enables capturing specific Events. Triggering facility on patterns, commands or error events.
  • User can identify the anomalies by decoding command and response arguments
  • Analytics feature provides analysis of acquired protocol data by plotting command, response, data and frequency of operation over acquired time
  • Analytics feature also provides the decoding of device registers for easy analysis
  • Filters allow you to view specific packets in decoded protocol packets
  • Search feature for specific events in protocol activity
  • Easy-to-use user interfaces saves time on learning curve
  • Handles long duration capture and displays the decoded data without demanding extensive resources in host computer
  • Inserting markers [using Trigger-In] in protocol activity helps in correlating the input digital signal with Protocol Activity
  • Trigger-out signal for any specific protocol event allows triggering of other instruments such as oscilloscope
  • Interface to host system [running UI] using USB3.0 or Gigabit Ethernet interface
  • Flexibility to upgrade the hardware firmware using GbE interface provides easy field upgradation of firmware
  • Export of Decoded data packets to txt file for further analysis

Setup

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.
