Overview
SoundWire-I3S interface is used for transporting data typically related to audio functions. The SoundWire-I3S interface addresses a wide range of system scenarios where up to eleven Peripheral interfaces share the common bus. SoundWire-I3S facilitates the development of low-cost, efficient, and high-performance systems.
As a part of product validation, it is important to validate the product’s conformance against the protocol specification to ensure the product’s interoperability. As the complexity of the protocol and product increases, the validation time of the protocol interfaces also increases, which, in turn, reduces the RTM. Performing the protocol conformance testing traditionally needs a lot of time and effort.
Soliton’s SoundWire-I3S Protocol Validation Tool is an off-the-shelf validation tool using NI’s PXI Platform, which helps to validate the device’s compliance with the timing and electrical specifications of the SoundWire-I3S protocol. The tool SoundWire-I3S also validates the device’s tolerance to and recovery from various SoundWire-I3S faults & exceptions and provides a comprehensive set of reports.

FAQ
How is this product different from existing Protocol Exercisers, Debugger or Analyzers?
This product is mainly used for performing functional and electrical compliance validation of the SoundWire-I3S devices (post silicon validation) whereas the other existing protocol exercisers, debuggers or analyzers are used for performing basic functional tests during the device bring up.
Can't I build a home-grown solution instead?
While this is certainly an option, we expect that it will take a highly experienced automation engineer between 3-6 months to create a 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 our comprehensive report or validation suite.
What else can I do with NI's PXI chassis/modules?
The PXIe-657x module is a general-purpose programmable pattern generator and acquisition device with deep memory. It can be used for other protocol validation tools from us. Also, it can be programmed using LabVIEW or other programming languages to emulate any synchronous digital protocol. 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.
What is the interposer board referenced in the system diagram?
The Protocol Validation Suite requires custom external circuitry for signal conditioning. Each purchase comes with a complimentary interposer board, which is a separate PCB designed and delivered by us.
Which oscilloscope models are supported?
The Protocol Validation Suite supports any NI scope by default. The tool has a flexible architecture that allows the support of other oscilloscope models. We can help you in building the oscilloscope plugin for one of your oscilloscopes.
What type of documentation and training will be available for each solution?
User manuals, Getting started guides, and tutorial videos are available for each solution and can be easily accessed from within the product. Additionally, we will provide short live training sessions upon request.
Can the tool be used for out-of-the-box validation?
Yes, The tool comes with out of box test scripts which can be used for validation after entering the device-specific details.
