How to instantiate a pcell in another pcell?

Hi,

The documentation is a good place to start for this, for example it contains this section:

 
Creating Instances within Pcells

It is often useful to create instances of other cells within a pcell. You can also create pcell instances within a pcell. For example, inside your pcell code, you can create the following:

    Get the cellview ID of the cell to add as an instance:

    cellId = dbOpenCellViewByType( gt_lib t_cellName lt_viewName)

    Create an instance of this cell:

    inst = dbCreateInst( d_cellView d_master nil l_point t_orient 1)

    If the instance is a pcell, use

    inst = dbCreateParamInst(
                d_cellView d_master nil l_point t_orient 1
                     list(
                         list( param1Name "float" 10.)
                         list( param2Name "string" "some string" )

                     ) ; close list

    ) ; close dbCreateParamInst

 Another function, in addition to dbCreateParamInst() is dbCreateParamInstByMasterName().

Hopefully the above information will help to get you started.  By the way, it often helps if you give information about which version you are using, since new functions are often added to the newer releases, and approaches to some topics change (e.g. things are often done differently in the OpenAccess database than they are under the CDB database) . The above was taken from the IC613 version but I think in this case it is the same as the IC5141 documentation (and the approach is the same too).

Lawrence.
