Prodigy | PGY-QSPI - QSPI Electrical Validation and Protocol Decode Software
 

Quad serial peripheral interface (QSPI) is a SPI module that allows single, dual and quad read access to external SPI devices. PGY-QSPI Electrical Validation and Protocol Decode Software offers electrical measurements compliance testing and protocol decoding as specified in QSPI specification. This software runs inside Tektronix windows oscilloscope and provides quickly all electrical parameter value and decoding of QSPI signals.

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 of offline analysis

Configuration Panel

Prodigy | 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.
