TU-RTN is an Octave (MATLAB) program which can be used to generate RTN waveforms using results from TCAD tool based on semiconductor devices.

To address these limitations, this work presents Vistar, a cross-platform, image-based desktop application designed for extracting parameter values from colour-mapped simulation outputs using segmentation and colour-value mapping techniques. The tool enables freeform region selection on exported simulation images and translates colour-based information into numerical data using a calibrated colour legend. By decoupling from proprietary TCAD platforms and operating directly on image outputs, Vistar introduces a universal, tool-agnostic approach to simulation data analysis. The application is built using a modern tech stack, Electron for the desktop frontend and Flask for the backend logic, packaged into a standalone offline executable via PyInstaller.
