Passing CDF parameters into subcells

Hi...May I see what exactly the subParams list looks like. The PCell parameters passed to dbCreateParamInstByMasterName() need to be a list of sublists with each sublist being a 3 element list identifying param name, type and value.

Thanks for having a look. The format of the subParams list is correct according to your description, but the values contained within are stale, and do not get updated with any change in the parameter form. However, the parameters at the top level do get updated correctly. The form of passthrough subParams and the lower level pcells are disconnected somehow. I saw an example of how to do this when using a mosaic containing the subcells by using dbReplaceProp on mosaic->instanceList, but that does not apply in this case as these subcells are flat placements, and I don't know what the equivalent would be. It seems things get more complicated when you introduce hierarchy inside a pcell.

Thanks

The main issue here is that you've not really provided enough information to know what you're doing wrong (or right). If you can't post the complete example here, I suggest you contact customer support.

Thanks,

Hi Andrew,

Here is a more complete example of what I'm trying to accomplish. In the following code, there are 2 pcells. "rectangle" is the higher level cell that parses the parameter list in the lower cell, and in turn calls the lower level cell "subRectangle" attempting to pass the cdf parameters through to the lower cell. I've gone through several unsuccessful iterations, but this is where it stands now:

let(()
when((cell = ddGetObj("CCSsandbox" strcat("rectangle") nil nil nil "a")) &&
(cdf = cdfGetBaseCellCDF(cell) || cdfCreateBaseCellCDF(cell)) cdfDeleteCDF(cdf)
cdf = cdfGetBaseCellCDF(cell) || cdfCreateBaseCellCDF(cell)

cv=dbOpenCellViewByType( "CCSsandbox" "subRectangle" "layout" "maskLayout" "r")
subParamList=list()
if( cv->isParamCell then
params=car( setof( param cv->prop param->name=="parameters"))
foreach( mapcar param params->value
k=symbolToString( type( param->value))
cond(( k=="flonum" k="float")
(k=="fixnum" k="int"))
subParamList=append( subParamList list( list(param->name k param->value))))
dbClose(cv)
foreach( parameter subParamList
cdfCreateParam(cdf
?name car( parameter)
?type nth(1 parameter)
?defValue nth(2 parameter)
?parseAsNumber "no"
?prompt car( parameter)
?parseAsCEL "no")))
cdfSaveCDF(cdf));when

pcDefinePCell( list(ddGetObj("CCSsandbox") "rectangle" "layout")
(
(subParamList ilList subParamList))
let((xPitch yPitch element subParams)
element=dbOpenCellViewByType( "CCSsandbox" "subRectangle" "layout")
break()
dbCreateParamInst( pcCellView element "" 0:0 "R0" 1 subParamList)
dbClose( element)
);pcell let
);pcDefinePCell
);cdf let

let((W H)
when((cell = ddGetObj("CCSsandbox" strcat("subRectangle") nil nil nil "a")) &&
(cdf = cdfGetBaseCellCDF(cell) || cdfCreateBaseCellCDF(cell)) cdfDeleteCDF(cdf)
cdf = cdfGetBaseCellCDF(cell) || cdfCreateBaseCellCDF(cell)
W=1.0
H=1.0
;Default parameter values:
cdfCreateParam(cdf
?name "W"
?type "string"
?defValue sprintf(nil "%.3f" W)
?parseAsNumber "yes"
?prompt "Width:"
?parseAsCEL "yes")
cdfCreateParam(cdf
?name "H"
?type "string"
?defValue sprintf(nil "%.3f" H)
?parseAsNumber "yes"
?prompt "Height:"
?parseAsCEL "yes")
cdfSaveCDF(cdf));when
pcDefinePCell( list(ddGetObj("CCSsandbox") "subRectangle" "layout")
(
(W float W)
(H float H))
let(()
dbCreateRect( pcCellView list( "y0" "drawing") list( 0:0 W:H))
);pcell let
);pcDefinePCell
);cdf let

subParamList (("H" "float" 1.0) ("W" "float" 1.0) )
