I am using Allegro PCB Design L and Allegro Design Entry CIS 16.3. All of my components are managed through a central CIS database (complete w/ footprints, part numbers, etc.)
I am having significant difficulties performing back annotation. When I finished laying out the board, I performed an auto-refdes rename. I was then able to successfully back annotate the design (after several attempts -- with identical actions performed). Later, I added a single component in the schematic side. I recreated a netlist, and imported it into Allegro. I placed the component, and re-performed the auto refdes rename. This time, no matter what I do, I am unable to back annotate the design. I get a large number of error in my swp.log file.
#549 ERROR(SPCODD-549): No physical part found for COMP_DEVICE_TYPE=RESISTOR_R0603_ERJ-3EKF2491V_22, regenerate the netlist to sync with Allegro board. ERROR(SPCODD-516): Line Number: 4#549 ERROR(SPCODD-549): No physical part found for COMP_DEVICE_TYPE=RESISTOR_R0603_ERJ-3EKF2491V_22, regenerate the netlist to sync with Allegro board. ERROR(SPCODD-516): Line Number: 5
I saved a backup before I did the second auto refdes rename. This should be a copy of the project where the .brd and .dsn files are in complete sync (i.e., right after importing a brand new netlist into the .brd). Even this is unable to back annotate.
Has anyone seen this and/or been able to solve it?
Can you tell me how you were able to resolve this issue?
Any help is much appreciated.
I have encountered this issue many times over the past few years, and was finally able to resolve it. The problem for me was that in Capture's Tools > Back Annotate window, it was looking for the wrong PCB Editor Board File. Once I fixed that, the back annotate worked properly and the .swp file showed all the refdes that I changed in PCB Designer.
