How to access parameters of an instance?

Hi Vijay

Perhaps you can use this:

procedure( printParams()
   let( (inst cdf)
      inst=car(geGetSelSet())
      cdf=cdfGetBaseCellCDF(ddGetObj(inst~>libName inst~>cellName))
      foreach( param cdf->parameters
         printf("Value of %s: %L\n" param~>name get(inst param~>name))
      ) ;foreach
      printf("Job done\n")
   ) ;let
) ;procedure


hiSetBindKey("Layout" "F10" "printParams()")

I'd also probably do either this:

foreach(mapcar prop inst~>props list(prop~>name prop~>value))

this won't tell you any properties not actually on the instance, i.e. those at CDF defaults.

The alternative would be to do:

cdf=cdfGetInstCDF(inst)
foreach(mapcar param inst~>parameters list(param~>name param~>value))

Which effectively does the same as Quek's except I'd change it to:

procedure( printParams()
   let( (inst cdf)
      inst=car(geGetSelSet())
      cdf=cdfGetInstCDF(inst)
      foreach( param cdf->parameters
         printf("Value of %s: %L\n" param~>name param~>value)
      ) ;foreach
      printf("Job done\n")
   ) ;let
) ;procedure

 If you are looking for the parameter values assigned to an instance of a pcell, you should get those values off the master. There may be some parameters not assigned through the CDF or some CDF parameters that are not pcell parameters.

inst~>master~>parameters gets the parameters off the master, including those that are the CDF default.

Thanks for the response. I have a doubt however, as I was trying the code:

cdf=cdfGetInstCDF(inst) , yields "nil" in CIW.

inst=car(gegetSelSet()) would throw the database ID as db:0x.......

cdfGetInstCDF whereas needs d_instID to work upon.

What I am trying to do is to access the "Parameter" tab of an instance placed in a cellview (layout) and trying to make comparision with condtions thereafter.

Hi,

I figured out the code above works all right for a proper CDF component viz. transistors.

In a tech library, the VIAS are not defined as CDF. I could figure it out from the cdf of it. I was wondering, what they would be, object wise.

Can I access the parameters of any object which are not necessarily cdfs?

Thanks,

Vijay

obj~>prop~>name and obj~>prop~>value if it's a database object  you're talking about.

Andrew.
