HSIC Protocol Trigger and Decode Analysis Software

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

Multi-Domain view

High Speed Inter Chip (HSIC) Protocol is being adopted very fast in the electronic design industry. Engineers designing the HSIC interface are finding it extremely difficult to debug this serial bus by manually going through the serial NRZI electrical signals in the oscilloscope and locating the problems. PGY-HSIC Protocol Trigger and Decode Analysis software allow HSIC Protocol-aware real-time hardware-based trigger to capture HSIC signals, decode and analyze them for any errors, bus status condition, and correlate protocol level information with electrical signals.

PGY-HSIC Software runs inside Tektronix Make oscilloscopes such as DPO/MSO5000, DPO7000, and DPO/DSA/MSO70000 oscilloscope series. PGY-HSIC utilizes the hardware-based real-time serial pattern to trigger, a long acquisition record length of up to 125MB to provide a superior HSIC Protocol Analysis Solution.

Easy HSIC Test Setup and Debug:


PGY-HSIC Software installed in Tektronix oscilloscopes can be launched by clicking on the PGY-HSIC icon in the oscilloscope desktop folder. Now the user has simultaneous view and control of oscilloscope waveform display as well as PGY-HSIC Software. PGY-HSIC Software is set to make all HSIC Protocol analyses. Users can analyze HSIC single acquisition mode, Repetitive mode, and as well as No Acq mode. In No Acq Mode, HSIC software analyses already captured the HSIC signal that is present in the acquisition memory of the oscilloscope.

Powerful HSIC Protocol Aware Hardware-Based Real-Time Trigger:

Simple easy-to-use HSIC protocol-aware trigger features allow engineers to capture HSIC signals at specific events in the HSIC bus.Select any of the live channels Ch1 to CH4 as trigger sources and set the trigger pattern. The trigger pattern could be either a Sync pattern to any PID packet. PGY-HSIC Software has the flexibility to choose a sync pattern that ends the ‘00’ pattern or ‘11’ pattern at the end of the 32-bit sync pattern. The threshold level allows the user to identify the right threshold to distinguish between logic 1 and logic 0. Protocol Aware trigger supporting trigger on sync and all PIDs.

Debugging of HSIC Signals:

  • CRC5 error
  • CRC16 error
  • Bit Stuffing error
  • PID Mismatch error
  • Invalid PID
  • EOP Length error
  • Frame Length error

Selecting any HSIC protocol packet data in the decode table highlights the corresponding electrical waveform in a detailed view. The Bus diagram below the waveform indicates the protocol data for the waveform. This waveform can be further analyzed by zooming out, placing cursors, fit to the screen. There is flexibility to snap and store the waveform image for a report with the flexibility to add comments for the image.


Searching for Specific PID, address, endpoint, and data allows us to focus on areas of interest in long record lengths up to 125MB of data.


While testing and debugging HSIC protocol using 100MB of oscilloscope record length, hundreds of HSIC packets are expected to present. In order to focus on the right packet of interest in the decoded, it is important to look for packets of interest. The filter feature in HSIC enables viewing the desired packets in the decoded data.

Documentation of Protocol Analysis

PGY-HSIC Protocol Trigger and decode Analysis software provides the flexibility of exporting the decode data in txt and CSV file format. Report Generation capability allows users to have different waveforms images including the oscilloscope screenshot in pdf format report. Report header, comments, and Test attributes can be added to the report.
