Overview

The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems 
 
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 SPI 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 SPI protocol. The tool can also validate the device’s tolerance to and recovery from a variety of SPI faults & exceptions and provides a comprehensive set of reports. Users have claimed that using this automated solution for SPI Validation has brought down the test time/ validation time from few days to few hours.

FAQ
What kind of engagement models is offered for SPI Validation​?

We offer 2 engagement models. In the First mode, the user can purchase a license of the SPI Validation Suite and do the validation in-house. In the second mode, the user can send us 3 DUT's, we will do the 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 SPI 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 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​
