Unrouted net

KobiC
KobiC over 5 years ago

Hi,

Among the components in my layout, I have a transformer and an electrolytic capacitor (see picture).

All the nets are routed, except this one. I've tried to think about everything - but for some reason, Allegro insist to keep them unrouted.

In layer #2 (Power), colored in yellow, there is a shape that covers them both, incluting thermal releif. It seems that they must be routed: both pins and shape in the same net name.

I have also checked the padstack of those 2 pins - both are defined well to all the layers.

At the top layer (green), the transformer pin also connected to SMT capacitors - very well.

What do you think?

    Try a Database Check first and see if that help. I'd also check all the connections on the net to make sure somewhere else on the board isn't missing a connection. If that doesn't help the padstacks and vias need to checked to make sure they are plated through holes and have pads on the relevant layers.

    Allegro Tools - Database Check, OrCAD Check - Database Check, check all the options and click on Check, then once complete look at viewlog.

    Thanks Steve! the problem was found: there was a small difference between the FP at the scheme and the padstack name.
