Passing CDF parameters into subcells

anomolousDoug

Hi,

I have a hierarchical pcell that requires parameters to be passed through from the property sheet into lower level pcells containing unknown parameters, but the parameters do not update with any changes or apply.

Currently, this is the approach:

.

.

cv=dbOpenCellViewByType( library subcell "layout" "maskLayout" "r")
subParams=magicallyGetParameters( cv); Extract list of parameters

foreach( parameter subParams

   cdfCreateParam( cdf blah blah blah))

dbClose(cv)

cdfSaveCDF( cdf)

-------------------------------------------------------

pcDefinePCell( list( library "TopPcell" "layout")

   ((paramA int paramA)

   (paramB int paramB)

(subParams ilList subParams))

.

.

dbCreateParamInstByMasterName( pcCellView lib subcell "layout" "Q1" 0:0 "R0" 1 subParams)

)

The subParams list never updates, and only the default values ever go in, even though all sub parameters are extracted and displayed correctly in the CDF form.

I imagine this probably has something to do with callbacks, but I just don't really understand them, or even know when they're necessary.

Thanks

    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.

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