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 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 SPI protocol. The tool can also validate the devices 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 Slave 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 Slave Validation Suite and do the validation inhouse. 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​.

Do I always need to test for full SPI compliance?​

No, this is not always the case. If your customer has a very narrow use case, or your chip’s SPI 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.​

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 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.​

Whether the tool can be readily used for validation?

Yes, The tool comes with readily available test scripts which can be used for validation after entering the device specific details

Can I build custom tests on top of SPI protocol?

The tool comes with flexible test editor that allows the user to create custom test cases using the SPI functions provided​

Peek and Poke GUI for exercising and debugging the SPI communication manually. User can configure any allowed timing/voltage parameters to debug the transactions. ​
