DRC Verification Problem

F

Guest
Hi All,
I am trying to run a DRC check on a layout placed and routed by Silicon
Ensemble and imported back into Cadence icfb environment. I am using
the TSMC 0.25micron library. When I try to run the Design Rule Check on
the layout, I get the following messages:

**********************
*Error* eval: undefined function - prependNCSUCDKInstallPath
*Error* load: error while loading file -
"/users/csegrad/fvohra/setrial/vts/tutorial/tsmc25/divaDRC.rul"

*Error* load: error while loading file - "*loadstring*"
Errors exist in the rules file
"/users/csegrad/fvohra/setrial/vts/tutorial/tsmc25/divaDRC.rul"
************************

I just added the definition of the library tsmc25 in cds.lib. Also the
layout from SE is also imported into this library. Is there something
else I need to do like installing the library another way or something.

I would greatly appreciate your help.

Thanks,
Fazela

I have to set the following shell environmental variables before
starting icfb when using the NCSU PDK. The CDS_SITE variable has to
point to the directory holding the PDK. I was working on a bug, so I
just installed it locally. Usually, it is in some central location.

setenv CDSINST `cds_root icfb`
setenv CDS_Netlisting_Mode Analog
setenv CDS_SITE ./ncsu_pdk
setenv SKIP_CDS_DIALOG
setenv SKIP_CDSLIB_MANAGER

My cds.lib has entries as follows to get to the NCSU libraries I was
using. You'll need different ones for TSMC.

DEFINE NCSU_Analog_Parts ${CDS_SITE}/lib/NCSU_Analog_Parts
DEFINE NCSU_TechLib_ami06 ${CDS_SITE}/lib/NCSU_TechLib_ami06

Edward,
How can you claim that they are environmental ? Is it their lack of CO2
emissions, or nuclear waste ? Do they refuse to give their value if the machine
is powered by an overly polluting energy co. ? Or do they contribute 1 cent to
WWF each time they are accessed ?

hmm ?

We have the NCSU libraries installed at one place as you said and I
just added their paths into my own cds.lib file. I also set the
environmental variables as you mention. But this still does not seem to
solve the problem.
I am unsure as to what else could go wrong.

Thanks,
Fazela

If all you can do is be pedantic and critical when someone is trying to
help, perhaps you should go to some group devoted to flaming and leave
those of us who are trying to help others alone. You are not funny,
amusing, or cute. But you ARE worthy of being blacklisted. I hope that
some day soon you will desperately need to ask a question of the person
who knows more about Diva than anybody in the world. And he won't be
able to hear you.

Too bad... I was trying to be funny. I am not a native english speaker
myself and value light hearted feedback when I make some mistake on the
jargon. You do not, but I could not guess that upfront. Sorry if that
upset you.

I did not post on-topic at first because I do not use the NCSU PDKs,
but I ll try to now to help Fazela.

Fazela,

diva does not see all the function definitions done by the NCSU
initialisation in dfII.

If the only function you need is prependNCSUCDKInstallPath() , you can
type that function call in CIW, take the return value and paste it in
your ruledeck in place of all the calls.

If there are more undefined functions, you will have to put their
definition in the ruledeck. For instance, if the NCSU initialisation
starts at the library definition, you could add something like
load(strcat(ddGetObj("tsmc25")->readPath "/libInit.il"))
and if the head of initialisation is some cdsinit file, it would be
something like
load(strcat(getShellEnvVar("NCSU_PDK_BASEDIR") "/etc/system.cdsinit"))

Just to add to Ed's excellent post, there is one more thing to do before the
NCSU kit will work.

In the main folder of the PDK you will see the files ".cdsinit", ".cdsenv"
and ".simrc".
Create symbolic links to those from your working directory, e.g.

ln -s /path/to/nscu-kit/.cdsinit .

The ".cdsinit" file will perform all the NCSU setup magic and define the
functions that are giving you the error messages.

Hope this helps,
Johannes Grad
 
Thanks!
It worked..
