How do you back annotate with a .swp file?

After re-sequencing is done in Allegro, it produces the report file called “rename.log”. This file is in plain text
format. We will use this file to produce the was-is file which later we will use it for back annotation in the
ORCAD schematics. Below is a sample rename.log file for an example.

Renaming components on BOTH_SIDES on entire BOARD
Extents: (-19900.0,-19900.0) (26100.0,16100.0)
Sequencing the Reference Designators SEQUENTIALLY
Row processing direction : to the RIGHT, from the top down.
Processing TOP of board, C340 has AUTO_RENAME property but is on BOTTOM, component ignored.
Processing TOP of board, C155 has AUTO_RENAME property but is on BOTTOM, component ignored.
OLD C1 NEW C1
OLD Q1 NEW Q1
OLD C2 NEW C2
OLD TP1 NEW TP1
OLD TP2 NEW TP2
OLD TP3 NEW TP3
OLD R1 NEW R1
OLD L1 NEW L1
OLD C4 NEW C3
OLD C5 NEW C4
OLD C6 NEW C5
OLD TP8 NEW TP4
OLD TP4 NEW TP5
OLD U1 NEW U1
(Note: Above section is what we need to produce was-is file)
Processing TOP of board, R172 has AUTO_RENAME property but is on BOTTOM, component ignored.
HARD_LOCATION property on J1, component ignored.
Processing TOP of board, RP67 has AUTO_RENAME property but is on BOTTOM, component ignored.
(Note: Above a HARD_LOCATION message , this prevents from that component to be re-sequenced)
How do we make a Was-is-file from Allegro re-sequencing file report (rename.log) ?:
Open “rename.log” file in a Text editor. Copy all the line starting with OLD xx NEW yy. Copy these sections
into a new text file. Once you go through the report file, and you made sure all lines are copied, (you can also
cut and paste which would be easier to trace if you missed any lines), save this new file as “was-is-file.txt”.
Now you have copied all replacement reports from report file to the new was-is file. All you have to do now is
to search and replace “OLD” with nothing and replace “NEW” with nothing. Basically, erase “OLD” and
“NEW” prefixes, we do not need them. The file can be any file extension, but essentially it is a text file
indicating each component reference update in a separate line. Beginning with old component reference
designator and “SPACE” and the new reference designator.
