Problems in opening OSU std cells for PDK45nm in virtuoso

[Koustav]

Hello,

I am trying to use the NCSU FreePDK 45nm technology kit and the OSU
standard cell
library. I am trying this on a SPARC machine running Solaris.

I have setup the Pycell Studio Kit and I have checked that it is
working fine. After this I have setup the FreePDK45 kit

I have untarred the OSU_FreePDK_std_cells.tar and OSU_FreePDK_Tech.tar

sourced the customized i) cadence.freepdk.cshrc (which in turn calls
the customized FreePDK45/cdssetup/setup.csh)
ii) source FreePDK45/cdssetup/icoa_setup.csh
iii) and copied the plugin files ciranova quickstart folder to my
OpenAccess folder. (oa/data/plugins).

After this I invoke Virtuoso and I find from its log window that it
has loaded the FreePDK customization.

However, after this when I trying to view any nmos layouts in the
library NCSU_TechLib_FreePDK45 or the layout of any standard cells in
OSU std_cell lib by double clicking on the layout view I get the
following error:

ddMapGetFileViewType:You are trying to run a CDB executable on an OA
library file..
_deValidateViewType: viewtype is nil

Can you please help me in figuring out what I am doing wrong? Your
help will be much appreciated.

Thanks,
Koustav

Hi Koustav,

As far as I understand, you seem to be using the wrong Cadence
version.
Your design data looks to be in the openAccess format whereas your
Cadence build looks to be in the old CDBA. This won't work of course.
You can check whether your Cadence version is CDBA or OA by typing the
following skill command into your CDS's CIW:
dbGetBuildInfo()
You can check it from Unix as well by typing :
getDBType

Cheers,
Riad.

Just a minor point, using the SKILL function:

dbGetDatabaseType()

is a good solution, as that's available in both CDB and OA. dbGetBuildInfo() is
for OA only.
