Annotate messes up multi-part component

dbemmann over 4 years ago

I have defined a component for a 74HC08 Quad AND gate. My component consists of 5 parts:

Part A: AND gate 1 (inputs A1, B1, output Y1)

Part B: AND gate 2 (inputs A2, B2, output Y2)

Part C: AND gate 3 (inputs A3, B3, output Y3)

Part D: AND gate 4 (inputs A4, B4, output Y4)

Part E: Ports GND, VCC

When I use the function "Annotate quietly", it messes up the circuit by exchanging Part A with Part E (which are obviously not interchangable). How can I fix this?

Have you tried locking the parts. You can do this in the library or at the schematic level. If you are gate swapping for placement purposes you might want to control this.

So I need to set this to locked in the library, for all parts of that component?

If you set it in the library then you also need to update the schematic instances from the library. Or you can lock it on the schematic and leave the library alone.

The other way is to configure part swapping in the library. Open the schematic library, and type "swap" in the search box. Click on "Tools->Configure Swapping". This presents a dialog box with all multi-part components. Choose one, and select "configure conmponent". On the "part swapping" tab, assign a number to any parts that can be swapped, and a different number for other parts. Also use the sequence id to identify which pins are funtioanly identical (eg AB for inputs, Y for outputs). Save the library, and update the schematic from the library component to get the changes.

You can also right-click a component in a schematic, and choose Part Actions -> Configure Pin Swapping to change things.

Great. I think this is the way to go.
