I would like to simulate a top-level digital testbench within Cadence ADE (that instantiates behavioural blocks for analog OR instantiates analog blocks).  

When I open ADE, and try to select the config view for the behavioural view, I get the following error.
*WARNING* dbOpenCellViewByType: Failed to open cellView (temp2 behavioral) from lib (my_lib) in 'r' mode because cellview does not exist.
*Error* Could not open ( my_lib temp2 behavioral ) in "r" mode.

The only workaround that I know of is to create an empty symbol for the behavioral testbench, and then instantiate this in a schematic.  However, this is not ideal.

Any suggestions?  Am I missing something obvious?  Or should this be a PCR?
