Newbie in Altium designer here. I have read the online documentation from Altium, however, I still have a warning when trying to compile my schematic in Altium:

my schematic: enter image description here

The warning says: unconnected line (xx, yy) to (XX, YY) and refers to the right and lower part of the bus. Strangely it doesn't complain about the left part of the bus. I drew the bus at once, in other words, it is not composed of two or more parts.

enter image description here

I have tried multiple things like inter alia redrawing everything, but the warning keeps being showed. How can I solve this issue?


This is my current schematic that still needs modifications: http://www.imgur.com/a/Zy1nK

This is the schematic mine is based on http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=spmu365&fileType=pdf (starts on page 36)

  • \$\begingroup\$ @Daniel I get the same error even when I just put a bus for the upper part like so: imgur.com/a/MD5vV . Does this give any clue? \$\endgroup\$ Commented Jul 17, 2016 at 19:45
  • \$\begingroup\$ Considering that these are graphical buses with no function other than to look nice, what happens when you delete them? \$\endgroup\$

  • \$\begingroup\$ Ignore it or delete the bus. You really need to clean up the way lines are crossing all over the place though. Honestly the bus is totally redundant, since virtually everything connects everywhere in your schematic. It's not like you're trying to differentiate between two different buses... \$\endgroup\$

1 Answer 1


I solved this issue labeling the bus, according with the lines it contains. E.g: your bus contains PF1, PF2, PF3, the label must be PF[1..3]
