problem with figs~>lpps~>layerName

ToMWUT
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?

  •  Hi,

     First, I strongly recommend that you use foreach instead of the for loops you show, it will be much easier to read and write and will be more efficient too.  For example:

     
    foreach( lpp cv~>lpps
     printf("Name: %s, Purpose: %s\n" lpp~>layerName lpp~>purpose)
    ); foreach

     As to why you get lots of 'nil' in you last section, it is because a figure will not have "lpps", that is a cellview attribute, rather a figure will have "lpp" which is a list of layer and purpose, and not an LPP object (which is what lpps is).

    Hope it helps!
