DesignSpark PCB V11.0.0Here we introduce trunk routing and provide tips for quickly achieving the best results.
This DSPCB Engineer feature allows two or more nets to be routed as a trunk or bus.
We first illustrate the simple SIL to SIL connector with one-to-one connections to show the very basic settings and options available as well as tips on how to achieve the best result.
This is followed by how to set the trunk track spacing.
Then how to adjust the trunk track spacing and offset the tracks.
The final illustration is for a DIL to DIL connector with one-to-one connections and how best to route these.
In a further article, we illustrate the special requirement on how to route a pair of tracks through BGA pads using specific track widths and spacing to achieve a defined impedance. This is easily achieved using trunk routing.
Watch this video for a step-by-step demo of setting up a trunk/bus route:
