@Mitch Bailey @Tim Edwards @mehdi ，Hi Mitch and Tim, when I run the precheck for my block, if I just check it singly, there aren't any errors, but when I put it into my big block, there are some errors, how can I solve this problem? It's a magic DRC problem.

I'm not sure why it would report an error in a larger context. It would help if you could zoom in on the reported error coordinates. But if it appears to be a false-positive error, then you don't need to worry about it, because magic error results are not used for submission pass/fail status.

Hi Tim, these are three of the errors, but I can't get more information about them. Are they belong to false-positive errors?

@Jianwei Jia If you haven't solved this, could you post your gds?

I have solved them, thank you, Mitch!
