Wiring problem on Eagle

Hello,

I got a problem because I can't wire to a component I created. First, I created a library for the component with Symbol, then Package and Device.

But when I am using this component on my schematic, I can't wire it. I used the same scale and grid for all the schematics and I updated libraries. But it is impossible to wire it.

If anyone has an idea to solve my problem ?

Hi Djib,

I hope you're doing well. Make sure that the part was made to a 0.1"

grid. Also in order to see the connection points clearly turn on layer

93 Pins in the schematic. You will now see lots of green circles one for

each pin. The center of those circles is the connection point, all of

your nets must start and end on the exact center of these circles(this

is why it's important to stay on a 0.1" grid). If you don't see green

circles on your part then that means you didn't use the PIN command and

you need to go back to your library and create pins. One final thing to

check make sure you are using the NET command to create your connections.

Let me know if there's anything else I can do for you.

Best Regards,

Jorge Garcia

Hello Jorge,

I turned on layer 93 Pins on the schematic and I can see green circles for each pin of my component.

Unfortunately, I still can't wire it because the nets don't start or end on the exact center of the circles.

Meanwhile, I used 0.1 inch grid for Symbol, Package and Device. Then, I updated libraries but it's the same problems with nets which can't connect in the exact center of the circles.

Seems that your device is not on grid. Why don't you just place it here.

A picture (eagle sch, brd or lbr) is better than 1000 words.

Hello,

Enclosed three pictures of the component I created in library. Symbol :

Package :

Device :

Yes, you are right, my component is not on the grid.

Coordinates :

RE pin : x= - cos(Pi/4)*8.5mm = - 6.01040764 mm

               y= sin(Pi/4)*8.5mm = 6.01040764 mm

CO pin :

               x= -cos(Pi/4)*8.5mm = 6.01040764 mm

               y= sin(Pi/4)*8.5mm = 6.01040764 mm

WO pin : x=0

               y = 8.5 mm

LO pin : x=0

               y = -8.5 mm
