Eagle sometimes does not include the power pins, as they are implied. It assumes you already know what pins go to (+) and to (-).I am using Eagle for the first time and I cannot find the Vcc and Gnd pins for both the Lm339 and 4001 ICs. I have attached a pic of the schematic.
Hmmm, I regularly place the unused comparators outputs to ground, it does nice things to the board layout. A LM393 can have pins 1,2,3, and 4 all grounded with no problem. Eagle will not allow this?Let me start by saying, I haven't used EAGLE in a long time. The symbols you are using for your supplies look to me like an "off page" type of connection. If you change it to a true supply type connection, which can be a small triangle or single arrow, you might not get the error. I don't have EAGLE on this machine so I can not direct you to the different symbols more specifically.
Also, do not connect the outputs of the unused comparators and logic gates to ground.
Sorry Bill,Hmmm, I regularly place the unused comparators outputs to ground, it does nice things to the board layout. A LM393 can have pins 1,2,3, and 4 all grounded with no problem. Eagle will not allow this?
It is still showing the errors. I do not know about the keep out areas. how do i find out about those. plus there is no connection between the led and anything on the board. the autoroute did not connect the led to anything. any idea why?Does it still give you the error?
It looks like there are two "keep out" areas on the board. Are those supposed to be there?
