I just met a big problem with Allegro 16.2.
I have layout all the pins on my 4-layer pcb. But I found one component had a wrong pin net name, so I updated it in Capture.
After then, I re-open the .brd file and want to update the pcb, at this time, Allegro PCB design GXL pop up a warning!
"WARNING(SPMHOD-34): Database was last saved by lower tier tool...
Allegro Expert. DRC is set out-of-date so you may wish to update DRC to insure design rules are being followed."
Does anybody know how to recover my design?
Or I must re-layout my pcb?
What a pity!
