I'm trying to back annotate reference designators to a DxDesigner schematic from a PADS .eco file.
When I try to do this, I get the following error message:
Error 6098: file Top_Block_Level.asc, line 3: Missing keyword *PARTTYPE*
I can't find any reference to PARTTYPE except in connection with http://supportnet.mentor.com/reference/technotes/public/technote.cfm?id=MG24982
which relates to PowerPCB.
I'm prepared to jump through hoops like editing the .asc or .eco files to get this to work; it is (I hope) a one off process to order the reference designators now that the placement is complete.
Any ideas what I should be looking for?
