Post by thread:[EE] Eagle question (also relevant to pic)

Hi, I want to use Eagle to draw my schematic. When ever I need to connect to a signal, for example GND, I want to place the GND as close as possible to the component, like in the schematics from microchip. This means that I need to be able to have many GND symbols but that they should all be the same net. Aparently Eagle does not let me do this. Is this right? Will

With Eagle, as long as your nets have the same name, they are connected, even if you don't draw a line representing that. If your put in multiple ground symbols ensure that they have the same net names. Then when you generate a board they should all show as connected.

I tried to add two gnd's, then eagle names them gnd1 and gnd2. If I try to rename gnd2 to gnd1 it doesn't allow that?

Then you're likely trying to change the name of the ground symbol. You need to change the name of the net by clicking on a wire not the symbol.

No. Eagle most certainly lets you do this. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products

Go to http://www.embedinc.com/pic/dload.htm and install the Eagle tools release. After installation you will find proper ground symbols in eagle/lib/Power.lib. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products

No, my gnd symbols are ok, someone suggested to rename the net rather than the symbol, and it DID work this time, so it seems to be what I need.

If you use proper ground symbols they will automatically name the net for you. You shouldn't be manually renaming nets when using ground symbols. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products
