Can anyone explain what happened to my design overnight - seemed fine when i saved and logged off, but this morning there are many DRCs due to a via being renamed with the prefix _DBFIX1, which of course is not in the via list.
I would like to understand if i did anything wrong or how to prevent in the future.
Take a look at this article on the Cadence support site Running DBdoctor creates padstacks with _DBFIX# name appended to original padstack (cadence.com)
