PMBus Protocol Analyzer and Exerciser
PMBus Protocol Analyzer and Exerciser (PGY-PMBus-EX-PD) is a Protocol Analyzer with multiple features to capture and debug communication between the host and design under test. PMBus interface is a chosen interface that works with a variety of power management products, such as AC-DC power supplies, and fan controllers.
PGY-PMBus-EX-PD is the leading instrument that enables the design and test engineers to test the PMBus designs for its specifications by configuring PGY-PMBus-EX-PD as master/slave, generating PMBus traffic, and decoding PMBus Protocol decode packets.
PGY-PMBus-EX-PD is easy to use in validation and manufacturing environments. It enables you to quickly configure a power supply in a very short period and allows customization by storing values into the device NVM. The PGY-PMBus-EX-PD allows power converters to be configured, monitored, and maintained according to a standard set of commands.
Key features
- Supports PMBus Specifications.
- Ability to configure it as Master/Slave.
- Variable data speeds.
- Generate PMbus traffic and protocol decode of the bus.
- A timing diagram of the protocol decoded bus.
- Listing view of protocol activity.
- Ability to write exerciser script to combine multiple frame generation at different data speeds.
- USB 2/3 host computer interface.
- Continuous streaming of protocol data to host computer to provide a large buffer.
- API support for automation in python or C++.
Multi-domain View
Multi-Domain View provides the complete view of PMBus Protocol activity in a single GUI. Users can easily set up the analyzer to generate PMBus 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 PMBus protocol activity.
Exerciser
PGY-PMBus-EX-PD supports PMBus 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 PMBus traffic as below:
Script line #1: Set system Frequency 1MHz, Duty cycle to 50%, CLK to data delay to 10ns
Script line #3: WRITE Transaction_Type
Script line #4: READ Transaction_Type
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.
Powerful Trigger Capabilities
PGY-PMBus-EX-PD supports Auto, simple, and advanced trigger capabilities. The analyzer can trigger on any of the PMBus Protocol packets. Advanced Trigger provides the flexibility to monitor Multiple trigger conditions and can set multiple state trigger machines.
