Hello Tien, thanks for your reply.
The nets i've shown in the example are normally connected to other components, on other pages of my design (via off-page connectors), the example i posted was just a cut and paste of one component to show the ERC warning.
My design has 8 pages, with some nets going between 2 or 3 of these pages. I am also having problems with a reset line that unfortunately goes to about 5 pages.
But your comment has made me think of something, when i add an off-page connector to one of these nets (U47 pin3 for example) the ERC warning disappears for that pin. It means that this net now has an off-page connector on both ends of the net (on both pages).
Do i need off-page connectors on both ends of a net travelling between two pages?
I thought one end would be sufficient because the net name is matched up successfully when using an off-page connector on only one side of the net.
Thanks again...
