Error while manual routing (Screenshots)

[chuck_toddN7PTC]

I was routing and an error was reported. I have taken a couple screenshots before clearing the dialog.

I was able to clear the error dialog and save my work.

Thanks.

Hi @chuck_toddN7PTC,

Thanks a lot for reporting this to us. I had a look and this doesn't seem to be a terminal error. It is good that you were able to save your work. We are trying very hard to replicate this sort of issues so any extra information you might be able to provide would be very helpful for us in tracking down the root cause.

Please let me know if there is anything else I can help you with.

Kind Regards,

I was routing on the TOP layer with push violators on. The trace was erratic moving several different elements since the area is really crowded. There were components on top and bottom layers.

Hi @chuck_toddN7PTC,

Thanks a lot for this extra information. I hope it'll help us replicate this issue. If you see it again please post here.

Kind Regards,

I am still seeing this error. I can replicate it periodically while manually routing.

The scenario is:

Finalizing my routing and tracking down airwire errors. I find that there are some tiny airwires that aren't connected on pins of components that have been routed. (airwire segments screenshot attached and circled, might be hard to see.) These are hard to get to connect. Some of the time I can delete the trace and try to reconnect to get rid of them.

The steps I use to replicate the error condition.

1) Turn on only layer Top (Bottom).

2) Invoke Routing command (R)

3) Turn off layer Top (Bottom). This allows me to see the airwire segment.

4) Click on airwire segment, layer Top (Bottom) will automatically become visible depending on which layer the segment seems to be associated with.

5) Error presents when I proceed to connect the trace.

With trace deleted, you can see in the attached image that there is a small airwire that seems to be off grid from the rest of the airwire. That is the trouble segment.

[chuck_toddN7PTC]

You can see that the components are at the same Y location from the component properties. The pads should be aligned, therefore the airwire should be straight pad to pad.

The airwire shouldn't have the small the 90 degree segments at both ends as seen in the reference_airwire.jpg.

I am using metric grid, primary is 0.05mm and alternate of 0.01mm.

[chuck_toddN7PTC]

I corrected the issue with these two capacitors by moving them -0.005mm to align their pads on layer TOP with the BGA pads on layer bottom. The airwire had no small segments at this point, but there's a 'X' over the aligned pads. See attached image.
