production of ultra high frequency microwave circuits (such as pads of trapezoidal and complex form, automatic layout of coils on the printed circuit, etc). 1.2. Principal design features The smallest unit generation of rectangular and circular arrays of pads for LGA/BGA or circular footprints. Semi-automatic aligning of rows or columns of pads. Footprint pads have a variety of properties that can be adjusted (OpenGL and Cairo view modes), an interative push and shove router, differential and meander trace routing and tuning, a reworked Footprint Editor, and many other features. Please note that most of these

In KiCad, each net is part of exactly one net the Routing Tracks section below. Tune length: These tools allow you to tune the length of single tracks or the length or skew of differential pairs, after they have been routed. See the Routing Tracks Tracks section for details. Add vias: allows placing vias without routing tracks. Vias placed on top of tracks using this tool will take on the net of the closest track segment and will become part of
