Autoroute

The Autoroute command uses an integrated strategy which automatically routes unrouted nets. This strategy cannot be modified, and obeys the pin exit directions that you set in Footprint Editor or eCADSTAR PCB Editor. These are set in the Pin Exit Directions dialog in Footprint Editor. However, you can override these settings in the Pin Exit Direction Settings dialog in eCADSTAR PCB Editor.

• To automatically route an unconnected net, click Net / Route > Routing > Autoroute on the eCADSTAR PCB Editor ribbon. In the displayed Autoroute dialog, select a value in the Lock angle mode box, and then click an unconnected net on the canvas. The unconnected net is routed using the Lock angle mode that you select.
• To automatically route between two pins on the same net, click Net / Route > Routing > Autoroute on the ribbon. In the displayed Autoroute dialog, select a value in the Lock angle mode box, and then click two pins on the same net, on the canvas. A route is automatically created between the two specified pins, using the Lock angle mode that you select.  

Value		Description
Specify track width		Allows you to override the track width settings that are specified in the Rule Editor Dialog. If track width settings are specified for the unrouted net in Constraint Browser, then these settings are also overridden.
	OFF	The track width settings are used that are specified in the Rule Editor Dialog. If track width settings are specified for the unrouted net in Constraint Browser, then these settings are used instead.
	ON	The Specified value box is made available. This allows you to enter the required width of the track. The value that you enter overrides the track width settings that are set in the Rule Editor Dialog. If track width settings are specified for the unrouted net in Constraint Browser, then these settings are also overridden.
Specified value		Enter the required width of the track. This field is made available when Specify track width is set to ON.
Lock angle mode		Allows you to specify that routes are only created by the Autoroute command at angles which are multiples of 45 degrees or 90 degrees, or that they are created at any angle.
	45-degree	If selected, then routes are only created at the following angles: 0, 45, 90, 135, 180, 225, 270, and 315 degrees.
	90-degree	If selected, then routes are only created at the following angles: 0, 90, 180, and 270 degrees.
	Free	If selected, then routes are created at any angle.
Delete Antenna		Allows you to delete any antenna patterns that are created by the Autoroute command.
	ON	Antenna patterns are deleted that are created by the Autoroute command.
	OFF	Antenna patterns are not deleted that are created by the Autoroute command.
Vias allowed		Allows you specify whether vias are allowed between multiple layers to create the shortest route.
	ON	If the shortest route uses multiple layers, then vias are added automatically.
	OFF	The route is created on a single layer, regardless of whether the route is longer than one using multiple layers.
