PXI-based I2C Protocol Validation

Go beyond basic I2C compliance. Generate advanced reports in minutes!

I2C (Inter-Integrated Circuit) is a synchronous, 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 package thus reducing the board space and cost.

Global Top 10 Semiconductor companies trust us for their I2C testing needs. Here's how our offering can expand your coverage and improve your workflow:

  • Comprehensive I2C interface characterization from experts:

    • Stay ahead of the competition by ensuring that your chip does not fail even in the corner cases, and can recover from a glitch or communication error
    • Win customers with the thoroughness of your compliance testing
    • Explore the ‘Features’ section to see how Soliton’s test goes above and beyond just a full sweep within the given spec

  • Save your designers valuable debugging time through our comprehensive reports. Our Validation Reports include:

    • Compliance summary
    • Digital scope shots
    • Debug and sweep information to help you reproduce errors
    • Step-by-step results that document the program flow

  • Here are two ways that you can benefit from our validation offerings:

Option 1: Soliton generates your I2C Test reports

  • Ship us 3 DUT boards
  • Receive a thorough and elegant electronic validation report in 2 working days!
  • * Shipping address: Soliton Technologies Pvt Ltd, #305, Tidel Park, Aerodrome Post, Coimbatore, India – 641014

Advantages:
  • We have years of experience with the tool and the PXI hardware, and can get you the best results from both
  • We understand the I2C interface and can advise you in interpreting and addressing any issues revealed in the report
  • Use our service in a time crunch and gain bandwidth to work on other pressing tasks

Option 2: You generate reports with our tool

  • Purchase our Validation Suite for a one-time fee
  • Generate your reports in minutes
  • * Operates on the linked NI PXI equipment. If you already have the NI PXIe-6556 which is now an obsoleted module and do not mind using obsoleted hardware, you can replace the PXIe-6570 in the linked part list with the PXIe-6556. The I2C Validation Suite will work both with the PXIe-6570 and with the PXIe-6556


Advantages:
  • NI’s PXI is a general purpose, modular framework and can be easily scaled for other tests besides I2C protocol validation using LabVIEW or other programming languages
  • If you already have the NI hardware, or intend to characterize multiple chips, this option may better fit your needs
  • Do not worry about customization capabilities. Our I2C test scripts are customizable on the TestStand and LabVIEW layers through a simple and powerful Script Editor tool

FAQs

  • Do I always need to test for full I2C compliance?
    No, this is not always the case. If your customer has a very narrow use case, or your chip’s I2C IP is exactly the same as a previously tested chip, then it is possible that you do not need the extensive validation that our service/suite provides.

  • 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 6570 or 6556 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 25ps line skewing resolution. NI’s PXI chassis supports high bandwidth and synchronization-friendly control and readback from a huge variety of digital, analog, and special-purpose modules in a compact form factor.
