New pin number found instead of Old one!.

Hossein1357

Hi,

I see a strange behavior in Allegro PCB 16.6. I swap a location - D17 pin in SP6 FGG484 package with AA2 - in Allegro PCB and apply back annotation. Then I want to find the D17 pin in schematic and surprisingly I find new pin number - here AA2 in our example - instead of what I looked for - D17 - and I can't find D17 any longer in schematic? Below picture depicts actually what I find in my search. Click on the picture to see it completely. Can anybody please help?!.

    Sometimes I see error messages in different stages of updating Schematic from PCB.

    1- I see below message in Allegro PCB when I want to export logic to Back Annotate Schematic:

    Error: Can't find destination directory 'D:/OrcadProject/REV5/SSPAV05_03/Net'.

    However, I select the Net folder again and run it successfully.

    2- When I want to Back Annotate schematic I see below errors in session log:

    ERROR(ORDBDLL-1108): No physical object present to attach property to.
       N6731110:  NET_PHYSICAL_TYPE   Part or Net stuff attempted, but failed
    ERROR(ORDBDLL-1108): No physical object present to attach property to.
       N6731110:  NET_SPACING_TYPE   Part or Net stuff attempted, but failed
    ERROR(ORDBDLL-1108): No physical object present to attach property to.
       N6730690:  NET_PHYSICAL_TYPE   Part or Net stuff attempted, but failed
    ERROR(ORDBDLL-1108): No physical object present to attach property to.
       N6730690:  NET_SPACING_TYPE   Part or Net stuff attempted, but failed

    3- I have two pins which I created a NetClass for them in PCB. Sometimes when I try to Back Annotate schematic I see this message in swap file:

    .Section2 UpdateProperties Nets UppercaseCombined
    "{Net Name}"    "NET_PHYSICAL_TYPE"    "NET_SPACING_TYPE"
    "N6731110"    "MECH&PROBE"    "MECH&PROBE"
    "N6730690"    "MECH&PROBE"    "MECH&PROBE"
    .End

    How come that after create netlist it removes these two special net from their NetClass?
