Yes invisible pins are auto connected. The Power pin not driven catches most new users out.
All that is happening is that DRC is checking that there is a source of power for a pin identified as power in. This can come in two ways, either a device that has a power out pin defined, such as a regulator, or in cases where there is no such device i.e. the power comes in from off-board, all you have to do is add a power flag symbol to the net. This tells DRC that you are providing power and that will sort things out. The only oddity is that GND is also considered a power in, so that needs to have a power flag on it somewhere as well. Have a read of the help document, there is a lot of useful tips in there. Andy On Sat, 27 Mar 2010 12:52:56 -0700 rocko <[email protected]> wrote: > Huh?
