ams simulation failure in icfb5

Hi,

I'm running ams simulation for digital (verilog) and analog (schematic) blocks in a single testbench using hierachy config.

In topcell.vams, I instantiated  i_cellA cellA(), and chose cellA as schematic in config file. 

The irun.log error is "instance 'i_cellA' of design unit 'cellA' is unresolved in 'worklib.topCell:vams'.". 

If I replace schematic view of cellA with an empty(port only) verilogams view, there will be no errors.

Thanks a lot.
