SKILL: How can I find available cellViews for a cellName?

Hi,
I want to start drc,lvs and rcx runs on the cells in a hierarchy and I
would like to know the available cellViews for each cell. I know this
is strictly not nescessary as I can code the viewnames "schematic" and
"layout" into my script. But I was curious if the cellViews are
available somewhere in the cv datastruct as composer present a menu of
available cellviews when I want to dive into the hierarchy.

 

Hi Svenn,

Not sure I understand correctly, as this sounds very simple.

Assuming you have a cvId, you can get the list of cellviews belonging to the same cell with

ddGetObj( cvId~>libName cvId~>cellName )~>views~>name

or

dbAllCellViews( ddGetObj( cvId~>libName ) cvId~>cellName )

If you are processing a hierarchy, you'll probably have an instId instead of cvId. instId~>libName
and instId~>cellName are readily available too.

If you want to find, say, layout views only, you can filter on the viewType == "maskLayout"

layoutViews = setof(
view
ddGetObj( libName cellName )~>views
member( "maskLayout" mapcar( 'ddMapGetFileViewType view~>files ) )
)~>name


Does this help?

Yes, I was poking around in cvId data structure to try to find some
usable stuff and forgot to look for a command doing this based on the
info that could be found in cvId. Kind of getting functionally blind
looking for solutions ....

Your filtering looks very nice, and as usual in SKILL, a nice little
brain twister.

Thanks for helping out,

 

You can try looking at the dbOpenCellViewByType command. I created a
nodeplot program that saves each net as a different view name. The format
to open a layout view is:

dbOpenCellViewByType( libraryname cellname viewname "maskLayout" "?" )

The ? would change how you want to open it... Since you want to run a DRC
run, you would want to open it in I *BELIEVE* "a" for append. Opening in
"w" will over write the data, and "r" is only to read. I *THINK* it's "a"
to modify, but I'm not sure...
