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.  ​
