PCell stream out issue

Hi,

I have a PCell which uses the bBox of the pcCellView
to align a guardring around previously defined instances.
E.g.
bBox = pcCellView->bBox
x0 = caar( bBox )-dxRight
y0 = cadar( bBox )-dyTop
x1 = caadr( bBox )+dxLeft
y1 = cadadr( bBox )+dyBot

This works fine in DFII 5.0 on CDBA database.
But now migrated to 5.1.41 on OpenAccess the PCell
guardring is aligned correct in the Layout Editor, but not
in the GDSII database, after a stream out.

Is there a difference how the Layout Editor and
Stream Out tool treat the 'pcCellView->bBox'?
Any ideas?

Thanks Bernd

 

Bernd,

You should log this with customer support. It doesn't sound correct to me.

Regards,

Andrew.

 

Hi,

I had the same problem. It's not that it's creating a corrupt GDSII
file, it's that 5.1.41 and 5.0.33 prior to September 2004 can't handle
the bounding box.

If you pull up 5.0.33 after September 2004, you don't see this
problem. I'm not sure if 5.1.41 new version has fixed this problem.

Just for information,
I reported this to customer support now,
PCR #764608.
I'll check this with 5141 USR1 next week, maybe
it's disappeared.
