The Power Management Bus (PMBus) is an open standard power-management protocol. This flexible and highly versatile standard allows for communication between devices based on both analog and digital technologies, and provides true interoperability, which will reduce design complexity and shorten time to market for power system designers.
As a part of product validation, it’s important to validate the product’s conformance against the protocol specification to ensure the interoperability of the product. As the complexity of the protocol and product increases, validation time of the protocol interfaces also increases which in turn reduces the RTM. Performing the protocol conformance testing in traditional way needs lot of time and effort.
Soliton’s PMBus Slave Validation Suite is an off the shelf validation tool using NI’s PXI Platform, which helps to validate the devices’ compliance with timing and electrical specifications of the PMBus protocol. The tool can also validate the devices tolerance to and recovery from a variety of PMBus faults & exceptions and provides a comprehensive set of reports. Users have claimed that, using this automated solution for PMBus slave Validation has brought down the test time/ validation time from few weeks to a couple of days.

No, this is not always the case. If your customer has a very narrow use case, or your chip’s PMBus IP is the same as a previously tested chip, then it is possible that you do not need the extensive validation that our service/suite provides.
While this is certainly an option, we expect that it will take a highly experienced automation engineer between 3-6 months to create the first version of a similar tool. To create a robust and flexible tool takes experience, and we have been improving this tool over the last 3 years since release. We believe it is worth the cost to skip the learning curve and avail of our comprehensive report or validation suite.
The 6570 module is a general-purpose programmable pattern generator and acquisition device with deep memory. It can be programmed using LabVIEW or other programming languages to emulate any synchronous digital protocol with 5ns resolution and 39ps line skewing resolution. NI’s PXI chassis supports high bandwidth and synchronization-friendly control and read back from a huge variety of digital, analog, and special-purpose modules in a compact form factor.
Currently, the tool supports PMBus spec version 1.3.1
Yes, The tool comes with readily available test scripts which can be used for validation after entering the device-specific details
The tool comes with a flexible test editor that allows the user to create custom test cases using the PMBus functions provided.
