SMBus Protocol Exerciser and Analyzer

PGY-SMBus-EX-PD is the leading instrument that enables the design and test engineers to test the SM Bus designs for its specifications by configuring PGY-SM Bus -EX-PD as master/slave, generating SM Bus traffic with error injection capability and decoding SM bus Protocol decode packets. SM Bus Serial bus interface has been widely used for voltage and temperature monitoring of the system.

Features
The product features are as follows:

• Supports SMBus 3.4Mbps Speed
• Ability to configure it as Master or Slave
• Simultaneously generate SMBus traffic and Protocol decode of the Bus
• SMBus Master and Slaves
• Error Injection ACK/NACK errors
• Variable SMBus data speeds and duty cycle
• Continuous streaming of protocol data to the host computer to provide a large buffer
• A timing diagram of Protocol decoded bus
• Listing view of Protocol activity
• Error Analysis in Protocol Decode
• Ability to write exerciser script to combine multiple data frame generation at different data speeds
• USB 2.0/3.0 host computer interface
• API support for automation in Python or C++

Multi-Domain view

Multi-Domain View provides the complete view of SMBus Protocol activity in a single GUI. Users can easily set up the analyzer to generate SMBus traffic using a GUI or script. Users can set different trigger conditions from the setup menu to capture Protocol activity at specific events and decode the transition between Master and Slave. The decoded results can be viewed in the timing diagram and Protocol listing window with autocorrelation. This comprehensive view of information makes it the industry’s best, offering an easy-to-use solution to debug the SMBus protocol activity.

Exerciser

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

Script line #4: Set system Frequency 1MHz, Duty cycle to 50%, CLK to data delay to 0ns, system inter message gap to 0us
Script line #6: SendByte
Script line #7: WriteByte
Script line #8: ReadByte

Timing Diagram and Protocol Listing View

The timing view provides the plot of SCL and SDA signals with a 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 the timing diagram for any timing errors.

The protocol window provides the decoded packet information in each state and all packet details with error info in a packet. The selected frame in the Protocol listing window will be autocorrelated in the timing view to view the timing information of the packet.

Powerful Trigger Capabilities

PGY-SMBus-EX-PD supports Auto, simple, and advanced trigger capabilities. The analyzer can trigger on any of the SMBus Protocol packets. Advanced Trigger provides the flexibility to monitor Multiple trigger conditions and can set multiple state trigger machines.
