Hi,
A colleague of mine has some weird experience when running Virtuoso.
We are using version: icfb.exe version 5.1.0 08/19/2008 01:12
(cicln04) $
1) After flattening one of the sub-blocks, it hung and suddenly just
crashed. The layout cannot be opened at all.
'panic.log' is created but it is empty.
My colleague can't remember whether she had a layout of the sub-block
she was flattening open in a different window.
-----------------------------------------------------------------------------------------------------------------------------------
*WARNING* couldn't build VM tables -- purging /home0/nieva/workspace/
projects/XFAB/work/TEST/HD_LED_top/layout2/layout.cdb
*WARNING* dbOpenCellViewByType: Failed to open cellView (HD_LED_top
layout2) from lib (TEST). Uninitialized XX error! Seek Help!
*WARNING* Data trigger for viewType maskLayout failed.
-----------------------------------------------------------------------------------------------------------------------------------
Could this be due to Virtual Memory limitations on our system?
'layout.cd%' , 'layout.cdb' , 'master.tag' , 'pc.db' files aren't
empty (but I don't know how to check the .cdb binary database file).
We're still stuck with this problem.
This next one is also baffling but we kinda 'fixed' it.
2) Whenever opening this particular library/layout (I didn't manage to
establish if the library or the top cell layout was the problem) :
LED_DRIVER_for2p28x3p30/top, the following log gets printed:

This ERROR message only comes up when she opens this library/layout
first. If she opens a different library first after login before
opening this problematic library/layout, the ERROR message doesn't
turn up. It is not known how this affects our work.
The workaround:
Concerned that the ERROR might lead to catastrophic consequences later
on, we tried to debug the problem.
I asked her to copy the library to LED_DRIVER_for2p28x3p30_2 thinking
that whatever path problem might be fixed when creating a new library.
When we restarted Virtuoso, opening the new library didn't create
problems, so I told her we could delete the original & rename/copy our
backup library to LED_DRIVER_for2p28x3p30.
However, she pointed out that I forgot to ask her to copy
hierarchically using the 'Update All Cells'.
So just as a precautionary measure, she logged out first & after
logging in, started Virtuoso. This time, the original library/layout
didn't cause the ERROR messages to appear when it is opened first.
I'm just assuming that copying to the new library must have caused a
Work Area path to be updated.
Best regards,
I-FAB
