How to check for unrouted Nets in Altium Designer?

With Altium Designer, you have a comprehensive unified design package that allows you to check electrical connections on your schematic, net connections on your PCB layout and make necessary changes easily. Let’s explore these tools for identifying and resolving any unrouted nets that may be in your design.

What do you call poor connections in Altium?

Such connections are often referred to as ‘Bad Connections’, ‘Poor Connections’, or ‘Incomplete Connections’. This rule can also be configured to test for such poor connections. All design rules are created and managed within the PCB Rules and Constraints Editor dialog.

How is routing completion defined in Altium Designer 21?

This rule tests the completion status of each net that falls under the scope (full query) of the rule. If a net is incomplete then each completed section (sub-net) is listed along with the routing completion. The routing completion is defined as:

Where does the ERC go in Altium Designer?

Although, some PCB design software packages have creating a netlist or running an ERC as a separate additional design step, in Altium Designer the ERC is part of the conversion or compilation that generates your PCB layout. The number of possible checks and violations is extensive and includes a number of checks that specifically deal with nets.

Why does Altium get mixed up with vias?

In my experience, Altium gets mixed up when vias are close together. When it says there is an un-routed net from via to via, try moving the vias farther apart (or make them smaller). You can also get more info about what Altium is thinking by going to Design -> Rules… and then select Electrical – Un-routed Net – UnroutedNet.

How to check via to pad in Altium?

Via to Pad – checking that the center of the via is placed on the shape of the pad. Via to Via – checking that the centers of the two vias coincide. Polygon to Track/Arc – checking that the center of the end of a track/arc segment is overlapped by the polygon.

Do you need electrical connection in Altium Designer?

In Altium Designer, this electrical connection qualification is a prerequisite that ensures you begin your PCB layout with all components fully connected.

What is the definition of unrouted Nets in PCB design?

For a manufacturable PCB design, unrouted nets resolution can be defined as the process of ensuring that all net connections are complete and fall within acceptable electrical and mechanical restrictions. This can be achieved by following the steps below.

How does via stitching work in Altium Designer 21?

Via stitching is run as a post-process, filling free areas of copper with stitching vias. For via stitching to be possible, there must be overlapping regions of copper that are attached to the specified net, on different layers. Supported regions of copper include Fills, Polygons and Power Planes.

How does via work in Altium Designer 21?

Track/Arc to Via – checking that the centerline, or center of the end of a track/arc segment, is placed on the shape of the via. Track/Arc to Pad – checking that the centerline, or center of the end of the track/arc segment, is placed on the shape of the pad. Via to Pad – checking that the center of the via is placed on the shape of the pad.
