Re: Failure in updating values for CDF with access operator

slim5

 Hi,

While trying to create a general procedure to modify the various parameters (e.g., w and numfinger) of a FET in schematic view, I encountered a problem that puzzle me. w and numfingers are the string listed under the Name column of Edit CDF. After opening the schematic view, I use the dBFindAnyInstByName to find the instance (N0) that I want to modify and executed the following code:
  dutInst=dbFindAnyInstByName(CV "N0")
  dutInst~>w="2.4u"
and this piece of code seems to work when I execute the following code:
  cdfFindParamByName(cdfGetInstCDF(dutInst) "w" )~>value

However, the value for Width did not get updated if I try to execute the following code:
  FETParam="w"
  dutInst~>FETParam="2.4u"

Did I do something incorrect or the access operator was written such that I must explicit use the name and not a variable?

Regards,

Su Lim

     Hi Lawrence,

    Thank you for the suggestion on using get and figure that I could use the putprop function to update the values for the properties of a symbol. While speaking to another coworker, he suggested that I could also use dbReplaceProp. Which of these two commands is the prefer method with respect to being more efficient?

      putprop(dutInst ParamValue FETParam) or dbReplaceProp(dutInst ParamName 'string ParamValue)

    With respect to the related callbacks, I had looked at that solution you mentioned and implemented it in my code.
