quartus layout mess after sopc update

Hey boys and girls,

I met a problem, I have a quartus project used a Nios2 with one PIO and SDRAM, in quartus, I "layout" all lines or bus one by one, after long run compiling, it run on my board, I feel very happy.

But yesterday, I need to add one PIO more, the modtity the SOPC and one PIO, re-gen it. But after update design in quartus, because of the growing nios2, my lines connected to SDRAM and old PIO MESS! I need to re layout them, it looks VERY stupid....

How can I work out the stuff? Thank you!!

    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.
