Dear all,
I am new to Eagle and I am current designing a PCB which have mixed signals. It is a 4 layer design with Signal, Ground, Vcc, Signal. Since I have an Analog ground and Digital ground, how can I create 2 ground supply parts, ie AGND and DGND since when I am changing their name or value, they are not seperating.
Please help me guys! Thanks!

Hello Savio,
First click on the letter i in the command button area, then click on
one of the ground plane borders. The Properties Box will appear where
you can select the amount of isolation for each ground and also the
order of priority by setting the Rank. Repeat for the second ground
plane and set Rank to the next higher number. When you click Ratsnest
you will notice the two ground planes will be separated.
Best Regards,
Mike
Additional I might say that you should use different symbols for
different grounds. Those can be found in the supply libraries. Of course
you can create them yourselves
