In PCB design, regulation of Design Rule design is the key that matters to a PCB to design success or failure. The intent of all stylist, reflect to the function of the design adopt design regulation this soul comes drive and implementation. Exquisite and meticulous regular definition can help the handy in the stylist job in PCB layout wiring, save a large number of energy of the engineer and time, help stylist realizes outstanding design intention, the undertaking that greatly convenient design works.

 

Whole PCB design needs definition of toe the mark. Incorporate the basiccest electric regulation (span, short circuit opens circuit) , wiring is regular (the line is broad, take line style, pass aperture type, fan goes out etc) , planar regulation (means of join of facing of power source n, means of the join that spread copper) ; With etc commonly used auxiliary regulation is like layout regulation, production regulation, high speed designs regulation, signal integrality regulation is waited a moment. After the design is finished, still can undertake regulation checks Design Rule Check to examine your design afresh, look have happen without the condition that violates regulation and try to improve and be perfected.

 

This second little skill solves a problem 6: How to set different area different regulation? The introduction uses Room to divide a divisional territory in AlTIum Designer, have corresponding regular setting and application in the light of this area next.

 

Set the line wide regulation in location with Room opportunely

 

In PCB regulation definition, want specific to area to adopt different regulation for instance, so Room is the first selection that solves this kind of problem. Give this one location to name with Room casing above all for Room1. Choose WithinRoom(”Room1”) in regular definition next, can think the object in this Room sets all sorts of regulation later. Issue plan institute to show for instance, line wide regulation was disobeyed entirely most value of flyer broad set, so green Gao Liang shows. The area casing that is right next chose Room1, installed 10mil of wider line wide value for its respectively, so the definition of normally of line wide magic figures drawn by Taoist priests to invoke or expel spirits and bring good or ill fortune in Room, it is normal to had shown, without green Gao Liang is violated compasses showed. But in the lead of same root network, besides Room still green Gao Liang shows violate compasses. This is the action that Room sets regulation alone.

 

 

 

 

 

After the casing in Room singles particular area, it is OK not just wide regulation of alone setting line, the random that still can install PCB Rule regulation to define a page to go up to it is regular.

 

Set the line span regulation in location with Room opportunely

 

For instance the setting regulation of span of whole PCB central line is as follows:

 

The smallest span is 10mil between each networks

 

Poor cent is right between the smallest span is 20mil

 

Of course the setting that this just has to show the effect of Room. Be in actually wiring when, all span include difference to divide pair of span between according to 10mil wiring. But to create a problem, poor cent is right between what span regulation installs is 20mil, as a result shows at when DRC is checked, appearing as follows to pursue wrong.

 

 

And we are the poor cent that accept 10mil span to taking a line, want to let should sign up for bad news to disappear namely. At this moment, use Room to set specific regulation to specific target can.

 

Use shortcut key D above all, m, r, namely Design>Rooms>Place Rectangular Room will found a new Room. Set phasing to answer for its regular. The object in Room sets regular term is Withinroom(’Room name ’) . Following plan institute are shown, will electric span setting is 10mil in Room.

 

 

Draw a Room next, the target that will use this spy to decide regulation (it is poor cent here to wiring) the cover goes in.

 

 

Apparent, 2 groups connect a line likewise the poor cent of same span is right, the target in Room is poor without the newspaper, use the regulation that builds Room setting. And the object outside Room still is condition signing up for a fault. This is the effect that Room sets regulation for different area.

 

Besides the application that sets specific regulation for different area besides the Room of above introduction of course, room still has two super good used skill. One is wiring of the layout inside the Room that applies Yuduotong to format answer is used, namely function of Copy Room Format. Another is will a kind yuan casing of parts of an apparatus is in Room, such pulling move place to use these yuan need to procrastinate only when parts of an apparatus move Room can. To these two convenient skill, everybody can try in the following job.
