ultiboard connections changed when transfered from multisim

[Behamore]

Hi Guys,

When I transfered a mulitsim file fo ultiboard most if not all the interconnects changed, only realised this when I had completed all the traces. I  transfered again using a different file name and when I place the first component the traces are incorrect, any ideas on how to fix?

Thanks in advance

James,

I'm not sure what could have happened my best guess is that you renumbered parts in multisim after you made the layout.

I don't know if a forward annotion would work in this case, you'll have to try

Make sure to make a copy of your current situataion...

Otherwise, I would suggest to leave your layout as it is, and take all components out of the board outline, and then place them back one by one...

first the easy ones: connectors and transistors etc....

Good luck!

Another reason could be is that you allow pin swapping in multisim..?

Check Options -> Sheet Properties -> PCB tab -> at the bottom PCB Settings: Pin swap and Gate swap

Thanks for the quick response, the problem was off my own making and all is good now.

Thanks again
