Planes and Restrict in EagleCAD

oldmanraskers
oldmanraskers over 8 years ago

Hi,

Using EagleCAD I have made a power circuit using a linear regulator and made little planes as recommended in the data sheet, however, when I route the board the software puts traces through these planes. I tried to use keepout but that didn't work and so then I went for restrict, which did keep the traces out but didn't make the copper pour! Does anyone know how I should fix this? Below is an example of what happens. You can clearly see the planes outlined with the dashed marks and the hatching is the restrict - ratnest did not make the copper pour but the traces did stay out image

Regards, oldmanraskers.

    No - you just won't be able to solder them MK

    Why not route that part of the circuit manually? It's not like it's a

    big job, and you want specifically to copy a reference layout, so just

    hand-route it. Most of the time it's quicker than faffing with an

    autorouter (any autorouter, this isn't a moan at Eagle's one, they all

    produce bad layouts that don't match what you're hoping for).

    I hear you Rob and I will no doubt follow your advice, but, now that I've found this problem I want to know how to fix it image

    I have managed to sort this issue by drawing a wire around the area that I want to restrict - this creates a border that wires will not cross and also allows the copper pour to take place image

    Looking at your layout the parts seem very close together to me - give yourself a bit more room between L1 and the big capacitor on its right and raise the chip a bit so the cap isn't too close.

     

    I agree about the auto-router - just say no to auto-routers (unless they cost more than your car !) !

    I have taken the advice and separated the components out - would components placed closely together cause unwanted noise?
