UFS (M-PHY) Protocol Triggering and Decode

UFS (M-PHY)

Universal Flash Storage (UFS) is a flash storage specification for mobile devices, computers and consumer electronic devices. The standard is being developed by the JEDEC Solid State Technology Association. The electrical interface for UFS uses the MIPI M-PHY and UniPro specifications that were developed by the MIPI Alliance standard body. The serial bus interface provides content-rich points for debug and test. However, since this protocol transfers bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1’s and 0’s to protocol requires significant effort; can’t be done in real-time; and includes potential for human error. Also, traditional scope triggers are not sufficient for specifying protocol-level conditions.

Extend your oscilloscope’s capability with The Keysight Technologies, Inc. UFS (M-PHY) triggering and decode application.

• This application makes it easy to debug and test designs that include UFS buses using your Infiniium Series oscilloscope.
• Set up your scope to show UFS and UniPro protocol decode in less than 30 seconds.
• Get access to a rich set of integrated protocol-level triggers.
• Save time and eliminate errors by viewing packets at the protocol level.
• Use time-correlated views to quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause.

UFS (M-PHY) setup, protocol triggering and search capabilities

• Get access to a rich set of integrated protocol-level triggers.
• The application includes a suite of configurable protocol-level trigger conditions specific to UFS. When serial triggering is selected, the application uses software-based triggering.
• With software-based protocol triggering, the oscilloscope takes signals acquired using either oscilloscope or digital channels and reconstructs protocol frames after each acquisition.
• It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.
