I have an older dsn which has been modified. The brd file to be updated is way out of sync with the dsn.
I am currently replacing all footprint info in the dsn to match the brd. Problem is that even though the symbols have been assigned an existing footprint, the netlisting keeps inferring that the "old" footprint still exists. Where can I fix this?
You might try refreshing symbols on a copy of the board and then use it to sync with.
In reply to redwire:
What I mean by way iout of sync.......... every footprint on the dsn is no where near the footprint on the brd.
It appears that this was an old version 14 brd that someone has been tweaking without revising the dsn. My assignment is to get them back in sync. I am assigning the brd footprints to each and every symbol in the dsn, but each time I try to create the netlist, some of the footprint errors seem to hang around.
My question is: by changing all footprints in the property editor of CIS cover all footprint issues, OR is there something else I may have to change as well?
In reply to pitbull107:
You need some alternative methods...not fun.
1) In the orginal design, export the placement. This will give a text file with the name of the symbol and its X/Y position and rotation.
2) If the ref des's did not change from the original board you can start with a new board and import the parts from the placement. Be sure that the symbol names match the DSN by either editing the placement file or making sure the DSN footprint matches that of the board.
3) If this works then you need to import the copper. This can be done with Export->Subdrawing on the old board and Import->Subdrawing on the new board.
4) From the sounds of it you are going to have a lot of clean up to do at this point. :(
Thanks for the info. I am not familiar with "export copper". Do you mean "copying the routing" into a sub drawing? If so, when I import it to the new brd, I will have tons of overlap....correct? Is there a way to "color" or highlight the subdrawing soI can tell what was imported? Also, will logic follow the drawing? Hopefully not, just a picture.
You're right.....not fun.
Not knowing exactly what changed I am assuming that by keeping *most* of the routing in place you will be able to recover the routing quickly by using a subdrawing. It does retain net/refdes intelligence. Those nets that don't exist in the new schematic won't import correctly.
This is going to require some experimentation on your part. And you may find it's faster to reroute :)
I found another "problem". The BOM I was given was incorrecr in a few spots so I had to update the DSN and re-netlist. Guess what....it blew away all my placement and edits! BUMMER!
Question: Is there a way to import another netlist without it blowing ? I did NOT check remove etch.
