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.

Pros: This application has the necessary modules for doing printed circuit work. Schematic capture is where it all starts. PCB layout module has a auto-router supported by auto placement. Component and pattern editor lets the user create custom component footprints and add to the library.

Extensive design related rule checking reduce the possibility of errors even before a schematic is routed. These include electrical rules check(ERC), design rule check(DRC) and net connectivity check. Net connectivity checks connections in schematics 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).

Manual placement features supplement the auto-place facilities to produce layouts quickly. The auto router can route a single layer or multiple layer with ease. External auto router use is supported. Smart manual routing tools allow users to finalize the design quickly. Design changes are controlled by the facility to compare the schematic and the PCD to ensure they are the same versions. Accurate shape-based copper pour system with different possible fill types and thermals can be used to make planes or to reduce manufacturing costs. 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 net-list formats and spice. Output formats are DXF, Gerber, Drill and G-code. Standard libraries include 50.000+ components.

Cons: It is always very difficult to assess how well these complex programs work in a wide range of designs for which it is used. One should look for user comments to get a good feek.

Overall: Quite a well designed application for an amazingly complex problem. The interface is quite simple and intuitive to use. Overall a rating of 4 stars is well deserved.
