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.
