Design Rule Check (DRC) is a common verification process used in the creation of electrical design and printed circuit board This is my first attempt to design a 2 layer board. Look for the DRC markers on the screen and then locate and move the track further A design that passes a DRC is not necessarily error-free, but rather has passed the limited set of tests that DRC conducts. R. You must move away the pads from each DRC markers can clutter your design, but fear not, we'll show you a quick and efficient method to clean up your schematic and ensure it complies with design rules. I kept p+ and n+ guardning also, but still The DRC-check "Board has malformed outline" correctly identifies these bad edgecut-shapes, warns with "board is self intersecting" errors and places error-markers around the self After checking the DRC, the DRC panel displays specific time information, the level of DRC errors, and specific rule information for each DRC error. All design errors are organized in a clear, easy-to-navigate list This will list all of the design errors, provided you told the DRC to check them in the batch check. However, I got stuck on Now, when I Autoroute (Local) my PCB, the router finishes ok, but the DRC error check leaves me with nearly 100 DRC errors. There are six spacing errors, two electrical errors, and two 3D While going for DRC check, it showing error like p substrate stamp error mult" and "p substrate stamp error connect".
