Rats Nest Incorrect Wiring


#21

Did you try the highlight net tool mentioned by @bobc?
Did you try to recreate the netlist and reimport it? (Do you perhaps get an error message when importing?)

And you never answered my request to state your kicad version.


#22

I’m reimporting the netlist several times to correct errors in the schematic, but it persists.

Where’s the highlight tool (I’m completely new to pcbnew)?


#23

Right tool bar.


#24

You can get the KiCad version number from the Help > About… menu item. Probably best to screen shot all the version information.


#25

He gave this information above. (Thanks @kiki for telling me about it.)


#26

The pins on the schematic are not numbered the same as the footprint.

Footprints usually go 1-8 starting at top left counting leftward/CCW.

Your symbol is

layout    1 2 3 4 5 6 7 8
schematic 2 1 3 4 5 6 8 7

If I’m reading that correctly. In which case your footprint ratsnest’s are correct.


#27

The ordering of the pins on the symbol does not need to be the same as in the footprint.

Assuming the red numbers in his screenshot are the pin numbers of the symbol then the ratsnet does not seem to connect the same pads as one would expect from the schematic connections.


#28

Sounds like a small test case using only the IC in question, along with something like an 8 pin header could clear things up quickly, and if the issues persisted, could be shared with the forum.

It would also be good to show the rat’s nest for the case when you have the footprint rotated by 90 degrees (to see if it is a rendering issue with overlapping lines). And to wire up tracks to see what is allowed.


#29

Agreed. Look again at Q27 layout. The white numbers are consecutive and leftward/CCW while the symbol has a slightly different pin order. I agree this is totally acceptable. And it means the ratsnets is correct according to pin numbers, not position.

Am I missing something?


#30

Dang it! Sorry for my confusion. I looked again and layout is 1-2, 3-4. While schematic is 1-3, 2-4.

Sorry for my wrong interpretation!

#32

@Rene_Poschl I was just doing exactly that.

The only suggestion I have is to suggest generating the Netlist in Eeschema again, then re-reading the Netlist in PcbNew.


#33

Search the netlist file and copy the Q27 part here. There is nothing wrong with having pins out of order in a schematic symbol.


#34

From the netlist:

(net (code 1) (name "Net-(Q27-Pad1)")
  (node (ref Q27) (pin 1))
  (node (ref Q27) (pin 3)))
(net (code 2) (name "Net-(Q27-Pad2)")
  (node (ref Q27) (pin 2))
  (node (ref R40) (pin 1))
  (node (ref Q27) (pin 4)))

Forum won’t allow attachments so here’s the lib data:-

@bobc posted the answer 2 times already (first time as post #5 even - remarkable - you just know when a person has experienced this bug often). :hugging:
You’re dealing with a graphical artifact in the PCBnew canvas.
Overlapping ratsnest lines (at least in the legacy canvas) cause that they vanish for that stretch.
I think the OpenGL canvas shows them.
This 99.9% happens at IC pins, as those are all in a row and at the same vertical/horizontal coordinate.
hit [F11] in PCBnew to confirm


#36

That is enough to see that the netlist is correct, pins 1-3 and 2-4 connected, so @Joan_Sparky has the true answer, a graphics drawing artifact. As soon as you attempt to add tracks in pcbnew, the rats nest will draw better.


#37

And indeed it does. At first I thought it may lead to incorrect wiring but then I found it won’t allow incorrect wires to be drawn, so it’s not a biggy.

Also the rats-nest frequently disappears. Switching to OpenGL and back resolves it. From searching I can see it’s a 6yr old bug. :slight_smile:
