Invalid DRC error?

#1 Post by Tomg » 21 Apr 2021, 15:54

Does anyone else see this invalid DRC error with the DipTrace example board named "BGA_autorouter.dip", or is it my setup? I did not change any settings after opening the board file. Even though the gap appears to pass the rule according to the displayed numbers, the DRC still flags it as an error. I have occasionally seen similar DRC "errors" on other designs before. Am I missing something here?...

I see the same. Probably the reason is very small difference between the rule and measured clearance. We will investigate the issue.
