PGY-I2C/SPI-EX-PD I2C/SPI Exerciser and Protocol Analyzer DataSheet

I2C Protocol Analyzer and SPI Protocol Analyzer(PGY-I2C/SPI-EX-PD) are the Protocol Analyzers with multiple features to capture and debug communication between host and design under test. PGY-I2C/SPI-EX-PD is the leading instrument that enables the design and test engineers to test the respective I2C or SPI designs for its specifications by configuring the PGY-I2C/SPI-EX-PD as Master/Slave, generating I2C/SPI traffic and decoding the I2C/SPI protocol decode packets

PGY-I2C/SPI-EX-PD I2C/SPI Exerciser and Protocol Analyzer DataSheet

I2C is a two-wire interface to connect low speed devices like micro-controllers, EEPROM’s, A/D & D/A converters, I/O interfaces, and other small peripherals in embedded systems. I2C bus is used by many IC’s and is simple to implement. Any microcontroller can communicate with I2C buses. I2C bus can communicate in slow devices and can also use high speed modes to transfer large amounts of data.

SPI is one of the widely used interfaces between micro-controller and peripheral IC’s such as sensors, ADC’s, DAC’s, shift registers, SRAM, and others. SPI is synchronous, full-duplex master-slave based interface. Both master and slave can transmit data at the same time. The SPI interface can be a 3 wire or 4-wire.

PGY-I2C/SPI-EX-PD is the leading instrument that enables the design and test engineers to test the respective I2C or SPI designs for its specifications by configuring PGY-I2C/SPI-EX-PD as master/slave, generating I2C/SPI traffic and decoding I2C/SPI Protocol decode packets.

Comprehensive Protocol Analysis using Multi-View

Multidomain View provides the complete view of I2C or SPI Protocol activity in single GUI. User can easily setup the analyser to passively monitor or use the exerciser to generate I2C or SPI traffic using a GUI or script. User can set different trigger conditions from the setup menu to 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 autocorrelation. This comprehensive view of information makes it industry best, offering an easy to use solution to debug the I2C or SPI protocol activity. Continuous streaming protocol activity to host system HDD/SSD ensures seamless roll mode operation without the need to recapture data when DUT/s are set to different states thereby saving test times.


PGY- I2C/SPI -EX-PD supports I2C or SPI traffic generation using GUI and Script. User can generate traffic using the GUI to test the DUT. Script based GUI provides flexibility to emulate the complete expected traffic in real time.

Timing Diagram and Protocol Listing View


Timing view provides the plot of Clock and data 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 analyse Protocol in timing diagram for any timing errors.

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

Powerful Trigger Capabilities

PGY-I2C/SPI-EX-PD supports simple trigger capabilities. Analyzer can trigger on any of the Protocol packet. Advanced Trigger provides the flexibility to monitor Multiple trigger conditions and can set multiple state trigger machine. User can initiate a timer and trigger on set timer values.
