Re: [PEDA] Different sized ground traces
Assuming you're using 99SE, then you can set up a net class for each group of nets with a particular width requirement and specify a width rule based on net class for each class. This is one rule the autorouter actually follows! Regards Andy Gulliver -Original Message- From: Mark W.

Re: [PEDA] Different sized ground traces
After re-reading your original email, I might have missed the point - if you want different widths on different parts of the same net then you'll have to route those segments manually as the autorouter ignores rules set by from-to, as mentioned in an earlier reply.

Re: [PEDA] Different sized ground traces
Of course we can route the board by hand. I was just trying to figure out if we could do it faster. Best regards mark DUTTON Phil wrote: Hello Mark, I understand your problem. You can assign a width to a net with the 'Design Rules'. To be able to pick out a particular connection within the same net to assign a different width (eg a 'sense' connection in a Power Supply you can use the 'from-to' editor. Here, you can create a particular 'from-to' between 2 nodes and then use the 'Design Rules' to assign a width constraint to that 'from-to'. I've not tried this in a design, as usually I would attend to this type of design manually rather than using an auto-router. This is where you need a good board designer who will manually route the board with an understanding of the requirements of the design with respect to current flow, thermal, voltage, DfM, etc. considerations. regards, Phil.
