Changing instance properties though SKILL

soathana

Hi everyone I am using SKILL to generate a schematic.

So I am using schReplaceProperty function, but i have some problems. How can I get the names used for the instance parameters? The way i do it is call:

inst=dbCreateInst(...)

inst=list(inst)

schReplaceProperty(inst "name" "value") 

So for  width appearing (in Property editor and edit object properties) "Total Width" this is not the case. Apparently When I insert for name  "Total Width" i get a user property named Total, apparently it does not like space :) 

ideas? 

thanks,

Sotiris

  • ShyJiun,

    There are two possibilities here. First of all, instance properties have objects of their own, and aren't directly visible on the inst object. There is a list of such property objects which you'd find as inst~>prop - so you could see the names with inst~>prop~>name and the values with inst~>prop~>value. Using inst~>totalWidth is a shortcut to avoid having to use dbFindProp to find the property, and then retrieve the value. However, if you have $CDS_Netlisting_Mode set to "Analog" then the inst~>totalWidth will first look for a user-defined property on the instance and retrieve that if it's there, and if not, it will look for a CDF property called the same thing and retrieve the default value.

    Regards,

    Andrew.
