dbReplaceProp with a mosaic

Hi,

I am using the following skill code to generate a mosaic of transistors:

dbMOS = dbCreateSimpleMosaicByMasterName(pcCellView procLib "nldmos_hs" "layout" "M1" 0:0 "R0" Ncols Nrows DevHeight DevWidth)

I want to set parameters of the cell nldmos_hs. When using dbCreateInstanceByMasterName to instance a single transistor, I use dbReplaceProp. However, I cannot figure out how to do the same when instancing a mosaic.

Also, in the icfb window I get a warning when creating the mosiac: *WARNING* invalid instance -- 527567744(mosaic).

Not sure if the two are related. Any help is appreciated!

Thanks,
Justin

Ok, so I answered my own question.

The command needed is dbCreateParamSimpleMosaicByMasterName. This command isn't listed in the manual, but it exists.

Hi Justin,

It is documented - perhaps it is not in the release that you are using though? I grabbed this from the IC615 documentation on COS:

dbCreateParamSimpleMosaicByMasterName
  


dbCreateParamSimpleMosaicByMasterName(
    d_cellView 
    t_libName
    t_cellName 
    t_viewName 
    t_name 
    l_origin 
    l_orient 
    x_rows 
    x_cols 
    x_rowSpacing 
    x_colSpacing 
    l_params 
    ) 
    => d_mosaic | nil

I hope this helps a little?

regards,

Lawrence.
