Additionally, since the PCB Editor is rules-driven, taking the time to set up the rules at the beginning of the design will enable you to effectively get on with the job of designing, safe in the knowledge that the rules system is working hard to ensure that success.įor detailed information on the checking of defined design rules, see Design Rule Checking (DRC). With a well-defined set of design rules, you can successfully complete board designs with varying and often stringent design requirements. Using the rule priority and the scope, the PCB editor can determine which rule applies to each object in the design. They cover every aspect of the design – from routing widths, clearances, plane connection styles, routing via styles, etc., and many of the rules can be monitored in real-time by the online Design Rule Checker (DRC).ĭesign rules target specific objects and are applied in a hierarchical fashion for example, there is a clearance rule for the entire board, then perhaps a clearance rule for a class of nets, then perhaps another for one of the pads in a class. These rules collectively form an 'instruction set' for the PCB editor to follow. The PCB Editor uses the concept of Design Rules to define the requirements of a design.
