PGY-QSPI – QSPI Electrical Validation and Protocol Decode Software

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

PGY-QSPI – QSPI Electrical Validation and Protocol Decode Software

Features

The QSPI supports the following features:

  • Single and Dual Transfer rate (STR/DTR)
  • Supports electrical measurements and compliance testing for Ext SPI, Dual SPI and Quad SPI
  • Supports Triggering on command index and on S# falling edge
  • Supports Analog and Digital Channels of Tektronix MSO
  • Automated electrical measurements with customizable reference level of QSPI electrical signal
  • Customizable measurement limit setup for pass/fail validation of electrical signal to enable measurements
  • Ability to store the QSPI protocol data and electrical data in CSV and txt format
  • Report Generation
  • Supports offline analysis

Configuration Panel

Configure panel helps in selecting the Signal Source, Such as Channels, Wfm Files and CSVFiles (Digital).Live Analog or Digital Channels of the oscilloscope can be used for analyzing the signal. The software decodes the data and displays both the protocol data and electrical measurements as shown below.Offline analysis is made using the stored .wfm fies (Analog channels data) or from csv file (Digital Channel data).

Limit Setup Panel

Limit Setup tab helps to set up the limits and reference levels of each selected measurements.In order to characterize and validate QSPI signals PGY-QSPI software provides graphical measurement reference level setup to set measurement reference level of QSPI signals.

Electrical Measurements

PGY-QSPI software provides extensive list electrical measurements are (DTR not supported):

  • Clock frequency for all commands other than READ
  • Clock frequency for READ commands
  • Clock High Time
  • Clock Low Time
  • Clock rise Time
  • Clock fall Time
  • S# active setup time (relative to clock)
  • S# not active hold time (relative to clock)
  • Data in setup time
  • Data in hold time
  • S# active hold time (relative to clock)
  • S# not active setup time (relative to clock)
  • S# deselect time after a READ command
  • S# deselect time after a non READ command
  • Output disable time
  • Clock LOW to output valid under 30pF
  • Clock LOW to output valid under 10pF
  • Output hold time (clock LOW)
  • Output hold time (clock HIGH)
  • HOLD command setup time (relative to clock)
  • HOLD command hold time (relative to clock)

  • Enhanced VPPH HIGH to S# LOW for extended and dual I/O page program

Protocol Decode

PGY-QSPI simultaneously decodes the QSPI signals along with electrical measurements. Software provides flexibility to view decoded command, address and associated data.

In detail view links the selected command to electrical waveform for easy debugging of protocol related problems.
