nlGetModelName

Hi All,

Long time no see. have spent a lot of time on the cadence
documentation with no luck. There is a missing link that I can not find.
I am trying to determine the model name of an instance that will be
netlisted. I am not writing a netlister, simply trying to determine the
model name that will be netlisted with a skill procedure. So, if there
is a completely different way that solves my problem I will be equally
happy. Here is what I am doing:


session = asiGetCurrentSession()
form=asiGetFormatter(session)
nl=nlGetNetlister(form)

So far so good. According to the documentation, the call is

nlGetModelName( o_instance )
=> t_modelName

unfortunately, I know of no functions that return o_instance. I can't
use the db functions because they return d_instance and nlGetModelName
complains about it. I am kinda stuck here. Any ideas?

Thanks in advance,
Stefano

 

Different approach , but how about that?

g_cdfId = cdfGetInstCDF( d_instId )
cdfFindParamByName( g_cdfId "model" )~>model

Sorry should be 'value'!

g_cdfId = cdfGetInstCDF( d_instId )
cdfFindParamByName( g_cdfId "model" )~>value

Hi Bernd,

Thanks a lot for your help. Unfortunately it will not work 100% of
the times. One can write CDFs that netlist with something that is not
the content of the model field, which is why I am trying to use the
netlister functions. Example: I could have a resistor R with "res" that
actually netlists with "abc" as model.

Take care,
Stefano

 

Hi,

Yes I intend to use nlGetModelName only after netlisting (so all
structures are correctly initialized, etc.). I tried
nlGetCurrentInstance on my design and got nil as answer. Sourcelink
knows nothing about nlGetCurrentInstance...

Thanks,
Stefano

 

Hi Stefano,

These functions can only be used within netlist procedures, called by the
netlister, so I think you're heading down the wrong road with the nl functions.

You might be able to use some of the "alm" functions to find this out - or
probably just look in the CDF...

(I'm off the network at the moment, and don't have time to look it up).

Regards,

Andrew.
