SKILL Q: Cycling through all open schematics and do somethin

Hi,

after reading a bit in the skcompref.pdf I find that there are many
functions that work on the current window or d_cvId. So far I havent't
found how to get all open d_cvId's as a list and then do something
with the schematics in all of them. Purpose is to have two or more
schematics side-by-side and then execute a command in CIW that
extracts a textual list of transistors and geometries of all open
windows and put them in a comma-separated list for Excel import. (or
whatever)

Hi Svenn,

Well, the functions you'll need are probably hiGetWindowList() and
dbGetOpenCellViews()

If you're looking for just those in windows, you'd use something like:

foreach(win hiGetWindowList()
when(win~>cellView
... do something...
)
)

Or if you want to be good and use the API:

foreach(win hiGetWindowList()
cv=geGetEditCellView(win)
getWarn() ; to swallow warnings about windows without cellViews
when(cv
... do something...
)
)

Andrew.

Hi,

after reading a bit in the skcompref.pdf I find that there are many

after a while the first idea came like this:

(setq cv (dbOpenCellViewByType "LIBRARY" "CELL" "schematic" nil "r"))
(setq instList (schGetMatchingObjects cv "cellName" "==" "*" nil))
(foreach cell instList
(setq symbol (car cell))
(println (dbSearchPropByName symbol "w")))

This way I get at least a nil for those symbols not having any w
property, but I can't get the value of that w. I just get a
db:12343213 reference back, and I can't say if it is a ddId a cvId a
bagId or whatever SKILL is calling these things. It seems to me that
there are many functions to set and change properties, but very few to
list them.

I tried to use some of the Bag functions or the ddGetObj, but they
complained that that the symbol above was not of kind ddId. This is
slowly getting on my nerves.

Hi Svenn,

What you get back is easily identifiable - use

(setq propId (dbSearchPropByName symbol "w"))

Then propId~>objType will tell you what kind of object it is.
Since this is a prop object, you can do propId~>name propId~>value etc.

Alternatively you could do:

(setq cv (dbOpenCellViewByType "LIBRARY" "CELL" "schematic" nil "r"))
(foreach inst (dbGetq cv instances)
(when (setq value (dbGetq inst w))
(printf "Width of %s is %L" (dbGetq inst name) value)
)
)

or something like that (off the top of my head). (dbGetq a b) is the same
as a~>b for a dbObject, but in LISP-speak.

Look in the Design Framework II SKILL functions manual, and it covers the
database in a lot of detail, especially how the db object model works
with the attributes of each db object.

Regards,

Andrew.

Hi Svenn

I think w is usually in the cdf and not a part of the properties of the
cellView. Some thing like this might do the job for you:

(setq cv (dbOpenCellViewByType "LIBRARY" "CELL" "schematic" nil "r"))
(mapc
(lambda (instance)
(println (getq (getq (cdfGetInstCDF instance) "m") value)))
(dbGetq cv instances))

Actually there's not really any point getting the cdf for the instance, at least
when you're in CDS_Netlisting_Mode set to Analog, because doing a
(dbGetq instance "m") or instance~>m will return either the instance property
or if it is not there, the default value from the CDF. Strictly speaking there
isn't such thing as an instance CDF - it's just a "virtual" structure which is a
combination of the instance properties overlaid on the cell CDF.

Andrew,

Thanks for the clarification. I will fix my existing SKILL code to
use dbGetq instead of cdfGetInstCDF.
