PGY-SPMI-EX-PD SPMI Protocol Exerciser and Analyzer

SPMI Protocol Analyzer(PGY-SPMI-EX-PD) is the Protocol Analyzer with multiple features to capture and debug communication between host and design under test. SPMI (System Power Management Interface) is a MIPI (Mobile Industry Processor Interface) standard with a 2-wire synchronous serial, a bidirectional interface that connects the integrated Power Controller(PC) of a System-on-Chip (SoC) processor system with one or more Power Management Integrated Circuits (PMIC) voltage regulation systems.

PGY-SPMI-EX-PD is the leading instrument that enables the design and test engineers to test the SPMI designs for its specifications by configuring PGY-SPMI-EX-ED as master/slave, generating SPMI traffic with time variation and error injection capability and decoding SPMI Protocol packets.

Comprehensive Protocol Analysis using Multi-View

Comprehensive Protocol Analysis using Multi-View

Multidomain View provides the complete view of SPMI Protocol activity in a single GUI. Users can easily set up the analyzer to generate SPMI traffic using a GUI or script. Users can set different trigger conditions from the setup menu to capture Protocol activity at a specific event and decode the transition between Master and Slave. The decoded results can be viewed in the timing diagram and Protocol listing window with autocorrelation. This comprehensive view of information makes it the industry’s best, offering an easy-to-use solution to debug the SPMI protocol activity. Continuous streaming protocol activity to host system HDD/SSD ensures seamless roll mode operation without the need to recapture data when DUT/s are set to different states thereby saving test times.



PGY-SPMI-EX-PD supports SPMI traffic generation using GUI and Script. Users can generate simple traffic generation using the GUI to test the DUT. Script-based GUI provides flexibility to emulate the complete expected traffic in the real world including error injections. In this sample, the script user can generate SPMI traffic as below.

Script line #1: Reg Write to the slave with USID 05
Script line #2: Reg Read to the slave with USID 05
Script line #3: Ext Reg Write to the slave with USID 05
Script line #4: Ext Reg Read to the slave with USID 05

Timing Diagram and Protocol Listing View

Timing Diagram and Protocol Listing View

The timing view provides the plot of SCKL and SDATA signals with a bus diagram. Overlaying of Protocol bits on the digital timing waveform will help easy debugging of Protocol decoded data. Cursor and Zoom features will make it convenient to analyze Protocol in the timing diagram for any timing errors.

The protocol window provides the decoded packet information in each state and all packet details. The selected frame in the Protocol listing window will be autocorrelated in the timing view to view the timing information of the packet.

Powerful Trigger Capabilities

Powerful Trigger Capabilities

PGY-SPMI-EX-PD supports simple trigger capabilities. The analyzer can trigger on any of the Protocol packets such as Reg Write, SLEEP or WAKE UP. Advanced Trigger provides the flexibility to monitor Multiple trigger conditions and can set multiple state trigger machines. Users can initiate a timer and trigger onset timer values.
