I hereby certify that I am not simply asking someone else to design a footprint for me.
This is an auto-generated message that is in place on the “footprints” section of the KiCad.info forum. If I remove it and ask for a footprint to be designed anyway, I understand that I will be subject to forum members telling me to go design my own footprint or referring me to a 3rd party footprint site.
Im creating a breakout board for attiny1616. I’ve designed most of it except one trace. Kicad doesn’t allow me to continue the trace after this point
I want to ask the obvious question. I cannot read the net name at the round pin 8 over on the right.
Are you certain that the netnames agree?
Is this pcb layout based on a schematic diagram netlist?
Also make sure that your design rules are not requiring too much space. I wonder if I am seeing that where the track is not quite connecting to the IC.
You have a mess in clearances.
Clearances around IC pads seem being smaller than I would expect.
Clearance around your track seems being bigger than a distance between IC pads and it not allows to route to pad or start routing from pad.
I’m not using KiCad since about half of year. Don’t remember all possible sources of clearance - but this clearance have to come from something. May be track belongs to netcalss for which you have set the bigger clearance.
For nets for tracks at pads 19 and 17 you had to have smaller clearance as you have routed them closer to pads 20 and 16 than gray clearance shown for track going to pad 18.
You can change the trace width and clearance for a single trace by selecting the routing tool, right-clicking, then choosing “Select Track/Via Width” then “Use Custom Values":
Sorta looks like your trying to route on the Front copper to a via on the bottom as your trace is red, you should put a via next to the pin like you have with the others. Or like the others have said it’s a clearance thing, but why one pin of an IC unless your schematic is wrong.
Looking at the 1st post, 1st image, the netclass is DEFAULT.
looking at the other pictures… since none of the nets have names I am going to guess all are DEFAULT and I am surprised you ever manage to breakout from at least 50% of the pads so this must be MARGINAL an a fraction of a mm here and there has resulted in this awkward situation where this one pad cannot be tracked out of
as @Piotr mentioned its an odd set of clearance… smaller around the IC but larger around the track and this would point to a default card.
1st place to go is the board setup → Constraints and align this with your board houses capabilities
you will see my DEFAULT is intentionally silly as I don’t like relying on default and this ensures I either have a safe tracked net OR I have a net I haven’t assigned a class too
FINALLY
custom rules to assist with tracking. less important for your card but fun non the less
