DipTrace is an advanced PCB design software application that consists of 4 modules: PCB Layout with efficient auto-router, Schematic Capture, Component and Pattern Editors that allow you to design your own component libraries. Besides being very simple to learn, which is quite an accomplishment for a PCB design software package, this solution has a very intuitive user interface and many innovative features. For instance, a schematic can be converted to a PCB with one mouse click. The board designer can instantly renew the PCB from an updated version of schematic and keep existing placement, routed traces, board outline, mounting holes and other work. PCB and Schematic can be compared at any design stage to ensure they are identical. DipTrace has a powerful automatic router, superior to many routers included in other PCB layout packages. It can route a single layer and multilayer circuit boards, and there is an option to autoroute a single layer board with jumper wires, if required. DipTrace also provides you with external autorouter support. Smart manual routing tools allow users to finalize the design and to get the results they want in a blink of an eye. Accurate shape-based copper pour system with different possible fill types and thermals can be used to make planes or to reduce manufacturing costs. Other important features are Electrical Rule Check (ERC), Design Rule Check (DRC) and Net Connectivity Check - the functions that check connections in Schematic by different rules (pin type, short circuit, etc.), the clearance between layout objects, which ensures board accuracy, and connectivity of all nets not depending on how they are connected (with traces, thermals or shapes). DipTrace modules allow you to exchange schematics, layouts and libraries with other EDA and CAD packages. DipTrace Schematic Capture and PCB Layout also support popular netlist formats. Output formats are DXF, Gerber, Drill and G-code. Standard libraries include 50.000+ components.
