I've had this question for a while. It has become more of an issue the bigger board I'm designing. Here it is:
First of all, I am using EAGLE 6.6.
I use two net classes to distinguish power connections from signal connections, with different trace thicknesses. This works well on smaller boards. There is plenty of space to run thicker traces.
But when I design bigger boards, some traces that connect say pullup resistors to 5V are also made thick by the auto router but really don't have to be thick. Making them thin saves space for more traces.
But if I go manual and thin out the traces, I fear that EAGLE doesn't understand what I did and will rely on this thin trace to daisy chain to thick power traces to power other parts of the board.
So are there any methods to tell EAGLE not to daisy chain certain connections such as when thinner traces are used instead of net-class defined thickness or am I worrying about things that will never happen? Thanks.
