By identifying and eliminating errors early, your boards will work properly the first time they are manufactured, so that you won't waste time and money reworking boards. Ultiboard's Design Rule Check can be run either in real time or in batch mode. The powerful Real Time Check will identify violations as they are made so that you discover errors as they occur, not when it is too late. The Real Time Check can be run either in full check or overrule mode. Full check mode will never allow you to commit a design error, while overrule mode will warn you that you are committing a design violation, but gives you the option to ignore the warning if you choose.
Design rules consider user specified values for trace, pad, component, and board outline clearances.
Because these values critically effect production cost, and are affected by your choice of routing grid, choosing strategic design rule properties is an important but sometimes difficult task. These 4 classes will automatically select design rules commonly used for each of easy, standard, dense, and very dense designs.
