SKILL help! How to get all the shapes of one kind from a Layout View?

I'm trying to get all the shapes of one kind from a layout view, such as all
the shapes of "Diffusion". Is there any function can do this?

Thanks

Try this

cv=geGetEditCellViews
foreach(shape cv~>shapes
if((shape~>layername == "Diffusion")
then
; Here shape is Diffusion

)
)


rds

 

function setof()

 

The code work, but you are using pCells and want to count diffusion in
the pcells too (I assume you do), then you have to flatten the whole
design first (unless there is a better idea, like searching through
each pcell for the specific layer)

 

One can ( without flattening a pcell) get to its contents ( shapes) by
using inst~>master~>shapes and do target matching.

where inst = selected pcell

doesn't leSearchHierarchy() search into pcells ?

 

Better would be to find the right layer purpose pair first, and then
get the shapes from that:

lpp=car(exists(LP cv~>lpps LP~>layerName=="Diffusion" &&
LP~>purpose=="drawing"))
lpp~>shapes

If there are a large number of shapes in a layout, there will typically be fewer
layer-purpose-pairs. If there are small numbers of shapes compared with the
layer purpose pairs present, the speed difference is small anyway.

The database is already organised into the different layer purpose pairs, so you
might as well use that to filter the shapes first, rather than processing all
shapes yourself.

Of course, this only deals with the shapes at this level of hierarchy. If you
want to get the shapes throughout the hierarchy, you'd need to either flatten
the design, or do a recursive search throughout the hierarchy (or use the
leSearchHierarchy function (or whatever it is called)).

Regards,

One way to get the list of all "Diffusion" shapes through the
hierarchy :

cv=geGetEditCellViews
diffShapes = dbGetTrueOverlaps( cv cv~>bBox list( "Diffusion" ) 0:20 )

0:20 means that the search will start from level 0 to stop
at level 20.
