divide signal wires in schematics

k.portman
k.portman over 12 years ago

Hello.

 

Is there any way to open in 2 a signal wire in the schematics editor?

What I'm missing is a way to divide in two a signal wire in the

schematics editor and keep the original names. Dividing a signal wire in

two can be achieved by deleting a (joining) middle segment of the wire.

Though, what now happens (in Eagle 6.4.0 and earlier) is that the longer

wire segment keeps the original name and the shorter segment receives a

new name (like N$33). How it now works is a standard and well documented

Eagle behaviour.

 

But this behaviour does not cover all usage cases. Often there is a need

to move/reorganize signals and blocks in schematics sheets. In this case

it would be valuable to be able to "open" the signal wires but keep

their original names throughout. Maybe a "Control+Delete" on wires could

be introduced to delete a wire segment but not change wire names in case

of a split...or am I unaware of some already existing feature?

 

I am aware that you can delete a middle segment of a wire and then

rename back the shorter part. The BIG problem is that if there also

exists a (consistent) routed *.brd file the wire delete in schematics

will also ripup some part of the routed wire in *.brd.

 

All this could be done by 1) closing the *.brd file, 2) ignoring "F/B

Annotation has been severed!" warning, 3) deleting wire, 4) renaming

back the shorter part, 5) reopening *.brd file, 6) running ERC to verify

consistency. Much easier/quicker/safer if there existed a

"Control+Delete" on wires (or similar command) in schematics editor...

 

Regards,

Kim

    A simpler workaraound is to add a third segment to the net and then

    delete one of the other. In this way there is no need to play with the

    (un)consistency.

    I don't think that works. I have tried several options, but found no

    native way to separate schematic wires without getting net renaming.

     

    True almost, there is one peculiar way it can be done:

    Group the (subset of) wires and components you want to separate from

    rest, move the selected group to another sheet. On the 2nd sheet you now

    have the divided part of wires keeping their original name. Now, if

    needed, this group can be moved back to the originating sheet. This

    option would not work in Freeware editiom, having only 1 schematics

    sheet available.
