Annotate symbol with design variables

ritterp

Hello,

I would like to add a label (by means of ILLabel guess) to the symbol whose value depends on global design variables. Let's imagine we had a symbol for a transmissionline segment consisting of a cap with value Par("C") and an inductor with value pPar("L"). When instantiating the cell we would set C=DESIGNVARIABLE_C and L=DESIGNVARIABLE_L. In the label I would like to see the result of ZW=sqrt(L/C), but values of the design variables (DESIGNVARIABLE_C and DESIGNVARIABLE_L) should be taken into accout. Is there any easy way to evaluate the expression sqrt(l/C) in SKILL? I have had a look at ael* functions to interpret expressions, but the parser seems to be unable to find out design variable values. I am using IC 5.1.41 with analog design environment for the global variables.

Thank you so much for your help,

 
Phil

    Hello Andrew,

     

    thanks! I have considered cdsParam(..) too but could not find a way to call functions like sqrt(L/C) in the paramLabelSet entry within the "interpreted labels information" section. Could you please tell me how to do that?

     Regards,Phil
