Worked on the emsec/hal repository to enhance the stability and data integrity of the Gate Library Manager through targeted bug fixing and GUI development using C++. Focused on reinforcing the application's robustness, the main contribution involved implementing a safety mechanism that disables open and create actions when a netlist is loaded. This approach prevents conflicting operations and reduces the risk of data corruption during gate library management. By strengthening state checks within the GUI, the update ensures that gate library actions are only available in appropriate contexts, laying a foundation for more predictable workflows and improved reliability in future releases.
