Title: How to add L and W of resistor in CDL netlist
Post by jaylin79 on Jan 17^th, 2006, 9:58pm

Hi guys,

Can somebody tell me how to let CDL netlist automatically add the size L and W of resistor? I can only know add the model and M of transistors.

Best Regards
Jay

Assumed you use Cadence DFII for CDL netlisting
(which tolls are used is always a helpful information)!?
You have to modify your CDF (Component Description Format)
of the resistor for CDL netlisting, I guess.

CIW -> Tools -> CDF -> Edit

!!! CDF Type must be Base

- Simulation Information

Edit there the auCdl Section to something like

cdfId->simInfo->auCdl = '( nil
netlistProcedure ansCdlCompPrim
instParameters (M L W)
componentName yourComponentName
termOrder (PLUS MINUS)
propMapping (nil M m L l W w)
namePrefix "R"
modelName "yourModelName"
)

or just use the SKILL command

cdfDump(t_libName t_fileName
[?cellName t_cellName]
[?level s_level]
[?edit b_edit]
)

to get the CDF information as text file, edit it and load it back with

load( t_fileName )

For more information about CDL netlisting refer to the Cadence online Docs
'Design Data Translator's Reference', Chapter 3 'Translating CDL Files'

bernd,

Thanks a lot, I can use your 1st way, yet I don't know how to find the SKILL file, where is it?

Best Regards
Jay

I do not know exactly what you mean with SKILL file,
maybe you misunderstood me.
cdfDump is not a SKILL file, it's only a SKILL command which dumps out the
CDF as a text file. OK, it's a SKILL format if you mean that, that
can be modified in a editor, rather than using the GUI to modify the CDF.

If you didn't find this file it's on you. What have you used for
the t_fileName argument. If you use just a file name without path
details it should be put in the directory form which you have started
the DFII.
Or try it with t_fileName == "./myCdf.il", I mean with a leading
./ before the file name.
Or maybe it's landed somewhere in your SKILL path, getSkillPath( )
returns the path.
