DipTrace is an advanced PCB design software application that consists of 4 modules: PCB Layout with shape-based autorouter, high-speed/differential signal routing tools, and 3D PCB Preview/Export, Schematic Capture, and Component/Pattern Editors that allow you to design custom component/footprint libraries. Besides being very simple to learn, this software provides wide engineering capabilities with intuitive user interface. Schematic capture works with hierarchical and multi-sheet schematics.
