Yet another Altium issue

[docmur]

Hey Guys

I've seen this in another post but that thread didn't help me.

I'm working on a new simple project where I've made most of my components.  I've made about 1/2 of all my foot prints and the other half are from the IPC standard footprint libraries.   My issue is that when I go to update my PCB I get the always annoying error:



All of my nets seem to have pin errors.  I've made sure all my pins line up with the foot prints I've used, 1 -> 1 and 2 -> 2 and I've made sure all my port pins in my schematic are physically connected to the pins of the chips.   I'm lost on what to try next, I've ran into this before but never really known what to do, usually I just go ahead and redesign all my footprints and link them back into the schematic.

It's errors like this that make me serious wonder how Altium can charge money for this program, given that it's only job is to effectually make a record of pin connections.

Thanks

Typically that happens when the schematic library can't link up with the footprint library, meaning it can't find the footprints.

In the schematic editor, open up the component property window of one of the parts in question. Then select the footprint model in the list at the bottom of the window. Hit the edit button which will then open up the footprint window. Does it show the footprint there?

Thanks for the advice!

That was the first thing I checked, I made sure all the footprints are still accounted for, I also clicked on the "Edit Pins" button to make sure the pin mapping was correct. 

The second step I looked at was the connection Matrix and made sure all my connected weren't causing errors, which they aren't.

I checked my library path and installed library path and they check out.  I'm still stumped.

Thanks

Check that schematic symbol and footprint pin names are identical.

All of my nets seem to have pin errors.

When an ECO places components on the PCB validation shows errors for pins which don't exist because the component has not yet been placed.

Execution of the ECO will not actually produces those errors if the placed components have the required pin names.
