Modgen Topology Constraints

Vishu21

Hi,

Cadence Virtuoso version- ICADV12.3-64b.500.18

In the help section find the term "Modgen Topology Constraints" 

There you see a list of different Constraints, Go inside 'Via control' , in the example given for via control Constraint they have defined in the following manner if you see..

list ("viaControl" nil 1

            list(stringToSymbol "viaControlOrient" Horizontal)

            list(stringToSymbol "viaControlInline" t)

            list(stringToSymbol "viaControlOffset" t)

             ...........

             .............

             ))

I am using the same list in my script but getting an error as "unbound variable stringToSymbol"

which is obvious as stringToSymbol is a function which requires a string as a parameter....

So i am not getting where i need to change the sytax !!!

Andrew please clarify!!

Thanks,

Vishal

    You are not calling the stringToSymbol function; e.g. the code piece "list(stringToSymbol "viaControlOffset" t)" calls the list function to create a list consisting of three elements: stringToSymbol (given as variable), "viaControlOffset" (given as string), and t (given as symbol).

    To call a function use either lisp style, e.g. (stringToSymbol "viaControlOffset") or C style, e.g. stringToSymbol( "viaControlOffset")

    Note, that in C style the opening parenthesis must directly follow the function name.
