An ML-aided Approach to Automatically Generate Schematic Symbols in PCB EDA Tools

The traditional manual drawing method of creating schematic symbols in current PCB EDA software is tedious and time-consuming. To address this problem, this paper proposes an ML-aided approach that can generate schematic symbols automatically and quickly. The approach effectively addresses the critical challenges of pin number-name pairing and direction recognition in package diagrams. Currently, the proposed approach supports both double-side and four-side symbol generation with high accuracy and efficiency. Compared to the traditional manual method taking several minutes to hours, the proposed ML-aided approach can generate a schematic symbol within one to two minutes.
