Place pcell with default values

SrBraj
In the virtuoso layout view, place a pcell and change any param(eg "w") value. Now place the same pcell again, the param("w") will have changed param value, not the default value.
In the skill script I want to keep the default values every time I place the same pcell. What is the better way to implement this feature?
One way that I can think of is to read the "defVal" from CDF and assign it to the pcell.
Or in other words, I am looking for is the skill API which can do the same job as the "Defaults" button in the "Create Instance" dialog box.
 
Thanks and Regards

    If you're placing an instance with SKILL, using dbCreateInst, it will have the default parameters. No need to do anything special. Or you could use dbCreateParamInst and you can pass specific parameter values - everything else will be at default. Neither of these will be influenced by what's on the form.

    If you want the create instance form to reset to defaults each time you use it, you can use:

    envSetVal("layout" "createInstResetCDF" 'boolean t)

    However, from your description, I suspect you don't need that unless your script is creating instances in a rather strange way.

    Hi Andrew

    Thanks for your reply. 

    I was using cdfUpdateInstParam() in my script, and this macro was setting the param value to changed param value instead of defaults.

    Thanks and Regards
