| Résumé : |
Modern semiconductor manufacturing systems comprise hundreds of interconnected components that must coordinate with precision. When these systems exhibit anomalous behavior, engineers face the challenging task of diagnosing root causes through analysis of traces (timestamped records of inter-component communication of messages and data). At ASML, the world’s leading supplier of photolithography equipment, this diagnostic process traditionally relied on manual conversion of trace les into sequence diagrams, a labor-intensive workow that introduced transcription errors. This thesis presents EzyTrace, a desktop application designed to automate the transformation of traces into interactive, enriched sequence diagrams. The tool parses ASML’s proprietary trace format, provides exible ltering mechanisms for time ranges, components,and other congurations. It outputs interactive sequence diagrams with tooltips and color codes. The tool also provides additional functionalities to assist engineers in their diagnostics, such as scope validation and reporting of unrecognized formats, among other features. The solution was developed following an iterative methodology across three development cycles, using PyQt to produce a cross-platform desktop application and integrating webview technology to enable interactive diagram rendering. Both graphical and command-line interfaces share the same core logic, following best practices and producing maintainable code. Manually transforming a limited number of lines into a sequence diagram takes between 15 and 30 minutes. EzyTrace reduces that time to a few seconds, eliminates manual transcription errors, and opens the door to working with larger volumes of data. The tool has been validated against ASML’s requirements and deployed within the company’s environment. |
