DRC [not really] gone nuts

(1/2) > >>

SpacedCowboy:
So Eagle has suddenly decided that the DRC rules don't apply - I'm getting hundreds of errors about the widths of traces being too small (at 3.5mil) even though the settings are set to allow that...

I also noticed that if I start to route a wire, it wants to do it at 6mil, and if I go to change it to 3.5 mil from the pulldown, it refuses the change and puts it back to 6mil...

It was perfectly ok with all of this yesterday - but apparently something changed. Is there some option I might be missing that says "override the DRU" ?

Kicad looking more and more appealing, but this is a relatively complex design (I'm up to 11 pages of schematic now) and I didn't want to jump into a new CAD package with that sort of project...

[edit, about 5 minutes after posting the above (of course)]

Leaving this as a warning to posterity - never assume there isn't a PEBCAK...

Yesterday I was working on the BGA side of this, today I imported parts of another design, and apparently merged my net-class lists during the import - I do recall a warning dialogue or two, but it didn't twig at the time... The minimum size of the default net-class on the other project was 6mil, and so everything on the board that was narrower than that was immediately flagged.

Changing the net-class rule for the default net was all that was required...

jpanhalt:
Which version of EAGLE?

SpacedCowboy:
9.6.2, but as mentioned in the edit, it was my own fault. And as is tradition, I figured that out just after posting about it :)

jpanhalt:
If you haven't learned yet, read about "restring."  That name is deceptive, but it is quite useful when doing a design.  I am stuck on EAGLE 7.x, which can do anything I've ever wanted to do.  I have a paid version and never updated.  Something about actually having the program on my disk appeals to me.

SpacedCowboy:
It's funny - I was looking for my 7.x license today so I could have something when the online license runs out. I'm not giving them any more money if they're not updating the application....

Anyway, turns out I can't find my license file for 7.x (got 4.x, 6.x, but not 7.x), so my 7.x key is pretty useless...

I'll give restring a look - it triggers a bell at the back of my mind, but I only use Eagle intermittently, so sometimes things fall out of primary cache :)
