Inevitable long hours of testing, designing a prototype, taking down measurements, logging of reports, debugging unexpected results, and of course, racing behind the clock– a very familiar picture to every Validation engineer!
Integral, Important and Inevitable
Validation is one of the most critical aspects which decides the success and longevity of a product in the market. This is especially true in the case of products having Digital Protocols interfaces such as I2C, MIPI I3C ®, UART, and SPI protocols. Validation holds as much relevance as the efforts put in designing them.
The following reasons substantiate this:
1.Validation ensures the interoperability of the product with other devices in the market.
2. Helps us understand the threshold limits of various parameters of the device.
3. Captures the bugs that might have been missed during design verification.
4. Identifies the behaviour of the device at corner cases which can be rectified accordingly.
Validation- The Conventional Style
Traditionally validation is done by building the emulator in one of the below forms
– Using FPGA/Off–the–shelf tools available for communication needs
– Using High Cost ATEs
In each case, the results are captured, analyzed and reports are generated.
However, these workflows come with a lot of pain points making them tedious, not to mention the amount of time that they consume. The following section highlights some key aspects of why validating in conventional methods is laborious.
However manual measurements lead to practical difficulties and errors. To note down the measured value, the Validation engineer must
– zoom in to investigate the values
– set the correct axes, channels, or cursors before logging values
– cross check if noted readings are correct
– ensure accurate measurements
All of these put a great amount of strain on the eyes, at the same time leading to errors. Efficiency is still not guaranteed when such activities are executed by humans, taking a toll on the final performance of the product.
Adding ATEs to the pain-point bandwagon
There is no less trouble while using ATEs,
Light at the end of the tunnel!
Given these numerous handicaps and challenges, Validation engineers look for solutions that can ease their Protocol Validation process. Not only must the Solution reduce the manual efforts during the validation process, but also be accurate and user-friendly. A solution that can test, log reports and aid in an easier debug would be the perfect choice for every Validation engineer.
