Add verilog configuration to a mixed signal simulation with config view

Hi,

I have a digital block (SV-RTL) whith a verilog config which I can simulate in a pure digital simulation using

xrun -top myrtl -compcnfg myconfig.sv

where myconfig.sv looks like:

config myrtl
  design worklib.myrtl;
  default liblist worklib ...;
  cell mycell liblist speciallib;
endconfig

This works fine for a pure digital simulation.

For AMS, myrtl is compiled into a library mylib using -makelib, provided to the simulator using -reflib, and there is a  verilogAMS wrapper myrtl_wrapper which instantiates myrtl.

Now I want to run an AMS simulation of a schematic ("mytop") containing an instance of myrtl_wrapper.

Hence, I have a testbench cell ("tb_mytop") with a config view ("config_ams") for simulating an instance of the cell (schematic) "mytop". The configuration config_ams is used to select the VerilogAMS view for the myrtl_wrapper instance.

• How can I now make sure in my AMS Simulation of "mytop" is using mycell from speciallib?

My first intention was to add a config, but then the questions arises, how that config should look like (e.g. name of config, design in config), since I expect that the config should be for the top, which is actually a schematic in this case.
According to the xrun.log -top is <vrituoso_library>.<testbench cell>:schematic_ams

But I did not suceed in creating and using the correct config (-compcnfg) so far. 

• Or maybe there is an alternative way of ensuring that mycell from speciallib is taken besides creating a configuration?

Thank's in advance for any help.
