Hi Lynn,
Beware that Librarian Expert doesn't recognize file based ptf's, only
cell based ptf's.

Lynn,
Not sure I can help out with the original question either. But I do
know (and have experienced) that having a large ptf file size will cause
Concept to slow down tremendously. We use a few ptf files for all
categories instead of the individual single-line ptf entries for each
part. I determined that one ptf file was causing the program to slow
down (over 90 sec. for Concept just to come up and about the same amount
of time for the component browser to come up). The solution was to
remove unused parts/split the file into two files to decrease the file
size and that helped with the speed.
Regards,
Carolyn

based using lib2cellptf -now cell ptf to lib ptf
All,
I can't help on this, but was wondering if anyone can help me...
We are exploring doing just the opposite -moving all cell ptf to a
library ptf due to a new application that we are looking into. I used
to have a couple of library level PPTs when I used Scald, but I don't
know if the rules have changed. Any help would be appreciated!
-directory structure, files needed, syntax, pointers etc. or is it just
a matter of copying all the ptf entries into one (or more) ptf files
like I did in scald? So far I've got one created with about 5 parts and
it works fine.
Does anyone know if there are any limitations to the amount of
symbols/file size or if there will be any problems (response time or
other) if we put all of our ptf files into 1 file.
Thanks,
Lynn

Subject: [PCB_FORUM] Changing library based ptf to cell based
using lib2cellptf
Hey,
I need to change my library ptf files to cell based ptf entries.
I'm using 15.51 on a Sun box and this is my directory structure;
/home/raid2/pmayer/cadence/library_development/ptf2cell/new_library/sch/
cdpas/cap_pol
/home/raid2/pmayer/cadence/library_development/ptf2cell/new_library/sch/
cdpas/capacitor
/home/raid2/pmayer/cadence/library_development/ptf2cell/new_library/ptf/
cdpas.ptf (This file contains ptf listings for both cap_pol and
capacitor. This is what we want to separate into ptf directories under
the symbol directories.)
The following is the command and response I receive;
lib2cellptf -product "PCB_LIBRARIAN_EXPERT" -cdslib ./cds.lib
-ptffile
/home/raid2/pmayer/cadence/library_development/ptf2cell/new_library/ptf/
cdpas.ptf -cell
/home/raid2/pmayer/cadence/library_development/ptf2cell/new_library/sch/
cdpas
I: License PCB_librarian_expert checked out
I: Opening project
/home/raid2/pmayer/cadence/library_development/ptf2cell/temp_proj.cpm
I: Cdslib
/home/raid2/pmayer/cadence/library_development/ptf2cell/cds.lib opened
I: Project
/home/raid2/pmayer/cadence/library_development/ptf2cell/temp_proj.cpm
opened
And then nothing happens... all the files are the same and in
the same place except I do get an empty temp directory, an empty
temp_proj.cpm, and a lib2cellptf.log with the following contents;
Library Level PTF to Cell Level PTF Convertor
Library Name Cell Name PTF Written
I was expecting both cap_pol and capacitor directories to
contain a .ptf in a ptf directory.
Anyone out there have any insight and/or experience with this?
Pattie
