Hello,
I wanted to calculate the MTBF of a PCB based system. It has PCBs distributed over a room, connected to a main module with wires. Pls. tell me how to do so.
Also as I understand, the wires and its soldering with the connectors to the main module is important to the reliability of...
It is a 7408 quad and gate(see my previous post). That is basically a standard part & available in eagle library. I tried by changing the grid. It is still showing the error.
Regards,

Hello,
I was connecting signal wires in eagle schematic to a IC (7408). After connecting it to power signal, when I did ERC, it is showing supply not connected. I tried by connecting the power signal wires both above and below the circular taps (it was not getting connected to central...
Hi,
Pls. tell me how to make a ground plane in Eagle. I surrounded the PCB inside with top metal layer polygon. Then, renamed it to gnd. But I am not getting as a PCB as in:
https://www.muzique.com/schem/eagle.htm
Kept isolate to 0.6096 and spacing to 1.27
Pls. advice.
Thanks,

Well, there were some tracks which were added on later (not from schematic). So while moving the components, these tracks remained in their original position. Hence, I made signal connections on the board, moved the components, deleted the manually added tracks and then re did the routing.
Hi Keith,
I found a way. I simply drew a signal wire b/w the pads and then deleted the previous track. Next, I did routing following the signal wire.
Thanks,
Y. Li
Hi Kieth,
The problem was solved. I had previously set the grid to finest which enabled me to route the board the way I wanted. Later I must have set it to some coarse value. Hence was not able to route the connections easily.
BTW I had one more query pls. I have directly placed some wires...
I was doing that... I selected the left most option.. but still when double left clicking on a pad, it is automatically showing a route between on of the possible destination pads. Previously, I was able to follow the signal traces between the pads.
Hello,
I am new to eagle lite and need some help pls. After I made the schematic and started with the routing of the components, initially I was able to follow the signal traces to do manual routing. Later on (something happened), the tool started suggesting the routes, ie I was not able to...
