problem with figs~>lpps~>layerName

Hello,

I have such a problem with my SKILL code and design:

My code looks like this

cv=geGetWindowCellView(window(3))

printf("\nALL LPPS (Layer purpose pair) \n")

; Here I want to check what LPPS I have in my design

;

for( i 0 length(cv~>lpps~>layerName)-1

printf( "LPP name: %s purpose %s \n", nth(i

cv~>lpps~>layerName), nth(i cv~>lpps~>purpose))

);for

printf("\n Figures belongs to LPPS \n")

print(cv~>nets~>figs~>lpps~>layerName)cv=geGetWindowCellView(window(3))

printf("\nALL LPPS (Layer purpose pair) \n")

for( i 0 length(cv~>lpps~>layerName)-1

printf( "LPP name: %s purpose %s \n", nth(i

cv~>lpps~>layerName), nth(i cv~>lpps~>purpose))

);for

; Here I'd like to check if all figs belongs to appropriate LPPS (2)

;

printf("\n Figures belongs to LPPS \n")

print(cv~>nets~>figs~>lpps~>layerName)

The problem is that in (2) I get an empty list (nil)

The result of the above code looks like this:

ALL LPPS (Layer purpose pair)

LPP name: pin purpose drawing

LPP name: device purpose drawing

LPP name: PO1 purpose drawing

LPP name: ME1 purpose drawing

Figures belongs to LPPS

(nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil nil)

Why is it so? Does anyone have any ideas?
