QSPI Protocol Exerciser and Analyzer

QSPI Protocol Analyzer (PGY-QSPI-EX-PD) are the Protocol Analyzers with multiple features to capture and debug communication between host and design under test. PGY-QSPI-EX-PD is the leading instrument that enables the design and test engineers to test the respective QSPI designs for its specifications by configuring the PGY-QSPI-EX-PD as Master/Slave, generating QSPI traffic and decoding the QSPI protocol decode packets.

Multi Domain View

Multi domain View provides the complete view of QSPI Protocol activity in single GUI. User can easily setup the analyzer to generate QSPI traffic using a GUI or script. User can capture Protocol activity at specific event and decode the transition between Master and Slave. The decoded results can be viewed in timing diagram and Protocol listing window with auto correlation. This comprehensive view of information makes it industry best, offering an easy to use solution to debug the QSPI protocol activity.

Exerciser

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

Script Line #1: PAGE_PROGRAM
Script Line #2: FAST_READ
Script Line #3: PAGE_PROGRAM
Script Line #4: FAST_READ
Script Line #5: SECTOR_ERASE
Script Line #6: FAST_READ

Timing Diagram and Protocol Listing View

Timing view provides the plot of CS, CLK, DQO and DQ1 signals with 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 timing diagram for any timing errors.

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

Setup View

Setup View of PGY-QSPI-EX-PD allows the user to configure the QSPI Chip select (CS), Clock Polarity (CPOL), Clock Phase (CHPA), QSPI rate of STR or DTR and the different modes of QSPI such as Extended, Dual or Quad.
