Overview

UART (Universal Asynchronous Receiver Transmitter) is an Asynchronous Serial communication protocol. The data is not synchronized with a clock instead the data bits are transmitted with pre-defined baud rate and appended with synchronization start & stop bits. It uses a two-wire interface (Tx & Rx) to communicate between devices.

 

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 UART 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 UART protocol. The tool can also validate the devices tolerance to and recovery from a variety of UART faults & exceptions and provides a comprehensive set of reports. Users have claimed that, using this automated solution for UART Validation has brought down the test time/ validation time from a few weeks to a couple of days.

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

We offer 2 engagement models. In the First mode, the user can purchase a license of the UART 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 UART compliance?

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

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