Overview
I2C (Inter-Integrated Circuit) is an asynchronous, 2-wire serial communication protocol. I2C Protocol is well suited for data transfer between ICs at relatively low speed. Its simple 2-wire interface simplifies IC design with fewer pins and smaller packages thus reducing the board space and cost. 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, the validation time of the protocol interfaces also increases which in turn reduces the RTM. Performing the protocol conformance testing in the traditional way needs a lot of time and effort.
Soliton’s I2C Validation Suite is an off the shelf validation tool using NI’s PXI platform, which helps to validate the devices’ compliance with the timing and electrical specifications of the NXP I2C protocol. The tool can also validate the device’s tolerance to and recovery from a variety of I2C faults & exceptions and provides a comprehensive set of reports. Users have claimed that using this automated solution for I2C Validation has brought down the test time/ validation time from few days to few hours.

FAQ
What kind of engagement models is offered for I2C Validation
We offer 2 engagement models. In the First mode, the user can purchase a license of the I2C Validation Suite and do the validation in-house. In the second mode, the user can send us 3 DUT's, we will do the I2C validation and send the test reports in 3 working days
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 I2C 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 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 its release. We believe it is worth the cost to skip the learning curve and avail of 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 reads 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.
What 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.
Whether the tool can be used for validation out of box?
Yes, The tool comes with out of box test scripts which can be used for validation after entering the device-specific details
Why was I2C Master- I2C Slave terms are renamed to I2C Controller I2C-Target?
As a part of terminology replacement efforts within MIPI Alliance, MIPI Alliance has deprecated the Master-Slave terminologies and replaced them with Controller-Target terminologies in MIPI I3C® specifications. Based on this NXP has changed the terminologies in the I2C specifications.
