quartus layout mess after sopc update

Hello,

I don't think there's a way of avoiding that. If there is I wish I'd known it several years ago because I've always adjusted my wiring manually following an SOPC change.

The only tip I can suggest is that before moving anything you turn off the button 'Use Rubber Banding' so that your wiring doesn't re-connect to the SOPC pin it now happens to align with. That way you can just draw boxes around blocks of wires/symbols and move them en-masse to the correct location. At least normally the existing ports are kept in the same order.

Have fun.
