Error when creating AMS simulation of the PDK using CIW- Conversion Tool Box

ncelab: *W,CUNOUN: Cannot find any unit under chrt18base.RFNMOS_1P8:spectre in the design libraries.
ncelab: *E,CUCFUN: instance 'NM0' of the unit 'RFNMOS_1P8' is unresolved in 'pllmml.dts:schematic'.

how can I solve this?

one solution:
Because the AMS simulation is different from spectre, so we must use the CIW-Conversion Tool Box-AMS simInfo form Spectre to creat the simulation information of the PDK.


After doing this, my simulation still can not run. why?
help!!!

CIW-Conversion Tool Box-AMS simInfo form Spectre
liberary name： the library name of the PDK ?
process allcells in the library: select or not?
process only cells with the following view: select or not?
if AMS simulation information exists:
only copy termmapping field select or not?
overwrite ams simulation information select or not?
mark a cell as a primitive:
if any of modelmame/model/modelname are found select or not?
if the cell has a spectre view select or not?
