eMMC/SD/SDIO Protocol Aware Triggering
For efficient testing and debugging of eMMC/SD/SDIO, it is important to capture signals in the right condition. PGY-MMCSD software provides protocol aware triggering along the serial pattern trigger option of the oscilloscope to capture signals at specific events in the CMD line.
- Flexibility to trigger on command or response
- Offers all the standard triggers patterns with command and Response
- Flexibility to edit trigger pattern
Automated Electrical Validation and Protocol Decode Software
As per the specification of eMMC and SD, the measurement limits are different for reading and writing operations. The PGY-MMC-SD measurement algorithms automatically find the read and write operations and validate with the respective limits. This enables you to save time in identifying the read and write operation and isolating any compliance issues.
- Lists electrical measurements with mean, minimum, and maximum values measured for the entire acquired waveform
- Indicates if the measurement exceeds the min or max limits by the orange color
- The lower and Upper limits of the electrical measurements are compared against measured values
- Supports Electrical Measurements as per eMMC 4.41 and 4.51 and UHS3.1 Specification.
- Automated identification read and write operation and apply electrical limits as per eMMC and UHS-I specification
Timing Parameters between CMD, Response, and Data
EMMC specifies the minimum and maximum cycles to present between the host and device to ensure interoperability. PGY-MMC-SD analyzes the data for these specifications and offers results.
PGY-MMC-SD software lists all the protocol activity between the host and card. Engineers can now quickly view the command and its corresponding response from the card. Selected protocol activity details are listed on the right side of the list table. Now Engineers can know the errors reported by card or any other message to host without struggling to know the content of each message.
Characterization of PHY layer by custom limit setup
PGY-MMC-SD is not just for standard electrical compliance testing, you can also vary the limits and test your device with custom limits. The intuitive limits and reference level setup allows you to configure the limits and reference levels for your custom testing needs. This enables you to test your device beyond the specification and characterize it.
Powerful Debug environment: Detail view
In Detail View, engineers can view the analog waveform, details of the protocol, and electrical measurements in a single view. If there is any failure in electrical measurement or error in protocol messages, designers can quickly correlate the protocol data with analog waveforms. These protocol errors can be caused due to the failure in electrical measurements. Users can select any row in the detail view; the corresponding analog waveform will be zoomed in and displayed. In the same row, engineers can view all the electrical measurements corresponding to the selected row. Utility features such as zoom, cursors, and markers make custom measurements while debugging.
Detail view provides the following capabilities:
- Plots the acquired waveform in the waveform view window
- Lists all decoded command and response tokens in each row in the decode table
- Identifies of type of command and response for easy protocol interpretation
- Lists respective electrical measurements for command and response for each row
- Selected Protocol command or response’s related analog waveform is plotted in a window.
- Bus Diagram view overlays protocol data for the selected row along with waveform
- Snap button enables storing selected waveform window for report generation purpose
- Zoom, fit to screen, pan, undo, vertical and horizontal cursors enables quick analysis and measurement of electrical signals
Industry First Decoding of CMD and data Signals:
PGY-MMC-SD leverages powerful capabilities of Digital Channels of MSO70000/5000 series oscilloscope to provide industry decoding of data signals in eMMC and UHS-I.
PGY-MMC-SD software automatically checks for Protocol Integrity. This allows a very easy method of ensuring protocol packets are as per protocol specifications of eMMC, and UHS-I Specifications.
