PGY-I3C-EX-PD I3C Protocol Exerciser and Analyzer

The I3C serial bus interface is emerging as a chosen interface for all future sensor connectivity in mobile phone and automotive industries. This could also be chosen as a low-cost, reliable interface for future embedded electronic applications to address the new data-intensive applications.

The PGY-I3C-EX-PD is the leading instrument that enables the design and test engineers to test the I3C designs for its specifications by configuring the PGY-I3C-EX-PD as Master/Slave to generateI3Ctrafficwith error injection capabilities and to decode I3C protocol packets.

Multi-domain View

Multi-domain View provides the complete view of I3C Protocol activity in a single GUI. Users can easily set up the analyzer to generate I3C/I2C traffic using the GUI or script. Users can set different trigger conditions from the setup menu to capture protocol activity at specific events and decode the transition between the Master and Slave. The decoded results can be viewed in the timing diagram and protocol listing windows with auto-correlation. State machine view provides switching of state machine between master and slave for design validation. This comprehensive view of information makes it an industry-best offering and an easy-to-use solution to debug the I3C protocol activity.


PGY-I3C-EX-PD supports I3C traffic generation using GUI and Script. Users can perform 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 the below sample script users can generate I3C traffic as below:

Script line #10: Set system Frequency 500KHz, Duty cycle to 50%, CLK to data delay to 10ns (default), start to restart setup time to 20ns (default)
Script line #12: SETMWL
Script line #13: Set system inter message gap to 16us
Script line #14: SETMRL

Timing Diagram and Protocol Listing View

The timing view provides the plot of SCL and SDA signals with bus diagram information. Overlayingofprotocol bits on the digital timing waveform helps in the easy debugging of protocol decoded data. Cursor and zoom features make it convenient to analyze protocol in timing diagrams for any timing error.

The protocol window provides the decoded packet information in each state and all packet details with error info in the packet. The selected frame in the protocol listing window will be auto-correlated in the timing view to view the timing information of the packet.

Powerful Trigger Capabilities

PGY-I3C-EX-PD supports auto, simple, and advanced trigger capabilities. The analyzer can trigger any of the protocol packets such as broadcast, directed, or private messages.  Advanced trigger provides the flexibility to monitor multiple trigger conditions and can set multiple state trigger machines.
