    Posted: 18 Jan 2017 at 1:11am
We use the Lite version of Library Expert to create footprints for OrCAD PCB 17.2.

Until OrCAD 17.2 S008 all worked fine.

But from OrCAD 17.2 S009 this is broken.

The sizes of the pads are way too big, so they cannot be placed (they overlap).

It seems that the script files that are used to make the pads now need to use the regional decimal separator setting (for us it is a comma) as decimal seperator, while before (until OrCAD 17.2 S008) it was fixed as a dot.

Since the script created by Library Expert uses a dot as decimal separator, this does not work anymore.

Note that the script for creating the outline etc (which also has a dot as decimal separator) is still working, so OrCAD seems to be inconsistent...

Uh... Yikes? I <3 Cadence :/.

Can you check if there is a setting that can be used which allows you to use the '.' instead of the ','?

Also.. are you able to pull the file into notepad and search/replace '.' with ',' and the part then actually imports?

Edit: I have the patch downloading.

Edit2: Got current to S010 and it appears to be working properly. Maybe this was a bug in S009, that they fixed rq? Try S010 and see if the problem persists.

Hi, thanks for your support.

Unfortunately there is no setting for this.

Yes, I already tried it as a work around, and it works. 
However, since the script file also contains filenames, replacing all dots with commas also breaks the script, so you have to manually replace them...

Sorry, I forgot to mention that I already have S010 installed, and the issue is still there. Do you have the ',' as decimal seperator ("Decimal Symbol") in your Regional settings?

There are 2 workarounds:
  • Changing the decimal seperator to a dot in the Regional settings.
    However, this is not preferred as we normally use the comma in the Netherlands, so a dot will be confusing.
    Also other programs may break when I change this...
  • Since I have OrCAD PCB 16.6 installed besides 17.2, I can create the footprint for 16.6, run the script with OrCAD 16.6, save the footprint, and then open it in 17.2.

Changing the regional settings to '.' to import the parts sounds solid. Is there any reason you can’t change it back afterwards?

I don't see the point of trying to jockey between , and . in the scripts. Just more added complexity. Good to see you've found a workaround.

Where are the regional settings for this located?

These 2 issues were fixed in V2017.07 pre-release – www.pcblibraries.com/downloads

 

·         Allegro/OrCAD PCB:

o   When the Anti-pad Size is smaller than the Pad Size, the translator will force it to be larger by .005. This is done to bypass the needless warnings from Allegro. It shouldn’t have any effect on the manufacturing.

o   Fixed an issue that was generating duplicate pad stacks for symmetrical pads at different orientations as found on a Chip Resistor, etc.

It's a Windows setting, see: 
Since it's a common setting for the whole computer, all other program's will be affected by this setting as well...

EDIT: 
BTW: I also notified Cadence about this issue shortly after S009 was released, but I haven't had feedback from them yet.

Hi Tom,
Thanks for your reply.
However, I don't see how the two issues are related to my problem.

Hi,

I just checked Orcad PCB 17.2 S011 (the latest hotfix from last weekend), and the issue is still not solved by Cadence...

Hi,

have you been able to reproduce this behavior?

I believe its an issue.. one that Cadence needs to rectify. They need to provide a setting for it in Allegro. Until then, you'll need to use the workaround.
