Purpose
The purpose of this PR is to significantly enhance the stability, usability, and workflow of the eSim platform. This work was undertaken during the Summer Fellowship Internship and focuses on addressing critical bugs and introducing productivity-focused features based on user experience insights.
Approach
This PR includes multiple contributions across the frontend and backend of eSim:
Fix: Simulation crash from lint_off.txt
a) Introduced exception handling to gracefully manage removal of non-existent entries in the lint_off.txt list.
b) Improved user feedback through warning dialogs instead of application crashes.
Feature: NGHDL model removal
a) Added "Remove Model" functionality to delete uploaded digital models.
b) Implemented backend logic to clean up associated files and UI references.
c) Included confirmation dialogs and robust error handling.
Fix: Auto-restore last opened project
a) Implemented persistent project path storage using last_project.json.
b) Ensures project continuity by auto-loading the last working directory on startup.
Feature: Snapshot and Timeline integration
a) Enabled file-level snapshot creation via right-click in Project Explorer.
b) Introduced a Timeline panel to track snapshots with timestamps and allow restore/clear operations.
c) Implemented restore logic for both individual and batch snapshot recovery.
Fix: Real-time file synchronization
a) Integrated file system watchers to reflect external file operations (add/delete/rename) in real time.
b) Ensured seamless updates in the Project Explorer without manual refresh.
