The XLAT-Evtool is a complementary application to the XLAT designed for developers, reviewers, and enthusiasts.

It makes use of the J-Link Virtual COM Port to read and parse data in real time directly from the XLAT. It extrapolates metrics such as lowest/maximum latency but also Median Absolute Deviation (MAD), Interquartile Range (IQR), percentiles, ... thus extending the functionalities of the XLAT.

Similar to the LDAT, it also makes it possible to export and import XLAT results to a CSV file. The CSV file not only includes the parsed data, but also features a list of the advanced metrics described earlier.

Last but not least, it makes use of Qt Graphics View Framework to provide a 16 steps latency distribution chart dynamically calculated based on data distribution and a Scatter Plot to visually assess latency behaviour over time.
