From 5774bdc4309fbed5eded7a6e7990b9ac55d7a0c1 Mon Sep 17 00:00:00 2001 From: codecraft Date: Fri, 10 Oct 2025 00:51:52 +0530 Subject: [PATCH 1/3] feat(drc): Add overlapping pad detection to Board DRC system - Implemented `checkOverlappingPads` function to identify overlapping SMT pads in the circuit. - Integrated overlapping pad checks into the `updatePcbDesignRuleChecks` method of the Board class. - Added tests to verify the functionality of overlapping pad detection, including scenarios for different shapes and subcircuit IDs. - Created a new utility file for overlapping pad checks and corresponding integration tests.

From: codecraft Date: Fri, 10 Oct 2025 01:07:58 +0530 Subject: [PATCH 3/3] refactor(drc): Rename overlapping pad utility and update imports - Renamed the `checkOverlappingPads` utility file to follow a consistent naming convention. - Updated import paths in the Board component and related tests to reflect the new file name. - Removed the old `checkOverlappingPads.ts` file as part of the refactor.
