In my design ,several nets have more than one name such as AGND & AGND_1234578,why?
Thanks.

this is because you havent offpage connection for page to page connection.
while u define the signal as a NET then u should use offpage from page to page, else u can use a global symbol . dont use the combination of global simbol (like GND) and the net name . this will also lead to the same problem .
its normally known as the net segmentation.

It will cause a fatal error, if you dont pay attention to it before import the net.
