The following procedure describes how use the Bus Route command to route multiple signals on a single layer.
- On the canvas, select more than two nets that require routing, and then click Net /Route > Routing > Bus Route on the eCADSTAR PCB Editor ribbon. Alternatively, click Net /Route > Routing > Bus Route on the eCADSTAR PCB Editor ribbon, select more than two nets on the canvas, and then click Selection End on the assist menu.
Note

- In the Bus Route dialog, specify any required settings.
- On the canvas, click a position close to the pins
at the start of the required route. This defines the end routing at
the start of the bus route, and allows you to start sketching a routing
path. An example is provided below.
- Create a routing path between the two end points
by clicking positions on the canvas. You can sketch over existing
design items when specifying this routing path. This is illustrated
below.
- Right-click close to the destination pins and select
Finish
on the assist menu. Alternatively, press the Spacebar
on the keyboard. If Single
click finish on snap line is selected in the Design

segments cannot be routed without errors, then they are left unrouted.
A finished route is illustrated below.
