How to tell if you have unmatched Nets in Altium?
Perform a transfer from your schematic to the PCB, Altium will warn you that you have unmatched nets. Just say “no” when Altium wants you to match them (Do you want to match those nets manually). This is Altium’s way of telling you: “Either you do it and control it manually or I will and do it automatically”.
What does Altium tell you about air wires?
If I am not mistaken, Altium shows the air-wires only between the component and the nearest pad/track/via of the same net. It does not show airwires to all connections with the same net. That would leave to a VERY messy ratsnest that would not help with routing at all.
When to use a blanket directive in Altium?
If there are a large number of pairs to be defined, an alternate approach is to also place a Blanket directive. This allows you to apply directives to multiple nets that are under the blanket (the software detects nets whose Net Label hotspot is within the blanket boundary).
How to create differential pair routing rules in Altium?
If the Net Class is not included, individual Differential Pair Routing rules will be created for every differential pair under the blanket. A Blanket can be used to configure multiple nets as differential pair members, create a Net Class of these nets, and apply a Differential Pair Routing design rule.
How are net ties used in Altium design?
This Paper Explores the Advantages to using Net Ties in Altium Designer to Join Multiple Nets (shorts) Into One Single Net at Very specific Locations in the PCB. Defining a Net Tie component can just be a matter of specifying it in the Type field of the Component Properties dialog in the right software.
How to hide connection lines in Altium Designer?
Select Nets view from the drop-down, then select . In the Nets section, double-click on a net to open the Edit Net dialog where you can verify the status of the “Hide Connections” checkbox. Another place to look:
