9v Battery - VDD and Ground Nets not connecting to battery

As the subject describes, I am having trouble connecting my +VDD and

-Ground nets to the 9v battery on my current board.

 

I am new to eagle software and am using some Sparkfun libraries. Can

anybody provide any insight?

 

I have fully designed the schematic with great success. When switching

to board view, to begin tracing out the components - I wanted to start

with the source: a 9v battery (thank you sparkfun for the cradle

footprint). I have the 9v going to a 5v regulator. The input of the

regulator I have connected to the net labeled "VDD" and the output is

connected to the net labeled "VCC."

 

The issue is that in schematic view, the battery's + and - terminals

clearly are connected to the VDD and Ground nets going to the 5v

regulator inputs. When switching to the board view, the battery's

terminals will not accept placing a trace to connect to the regulators

footprint.

 

What am I doing wrong? The cradle has 2 pins providing a direct

connection to the board from the battery. The footprint for these pins,

or the two pads, will not accept a trace being placed to make the

connection to the regulator.

 

Can anybody identify where my mistake lies?

 

I think you (mis-)used the bus command to draw part of your

connections.

That won't work. The purpose of a bus is to bundle multiply signals.

It never connects directly to a pin. A netstub is allways needed to

determine which signal (from the bus) is connected to the pin.

Run ERC and you will get a list of issues you need to fix.

It looks like the connections are not properly made on your schematic.

The blue traces on the schematic are not proper connections they are probably bus lines or just blue lines.

To make these connections, use the Wire tool on the green 91 Nets layer.

NO! BAD ADVICE!

Don't use the "WIRE" tool to make nets, use the "NET" tool.

(Although the wire tool is closer to working than the bus tool!)

Not to worry much about it follow these simple steps

1.) Open the layer selection dialog box.

2.) In that select the "Pins Layer" and hit apply.

3.) After that you will see some bubble kind of things around the pins of each component, as shown below.

4.) Now connect a net to that bubble and connect to another components pin with the bubble, or simply use the junction tool, below buss tool.

Actually connection is from bubble to bubble, not any other part of the component.

Connection is possible when there is a bubble. If pins layer is disabled then also connection is between bubbles.

that plus symbol with a dot in center. use that.

If there is no connection between two pins i.e. bubbles, no net will be seen on the board.
