a problem with RFDE2008

after installing RFDE2008, I simulated a simple circuit. But there's an error message. The error message was below...

----------The error message----------------------------------------------------
Error detected by hpeesofsim during netlist flattening.
Undefined parameter 'off' used by 'Q0.region'.

hpeesofsim terminated due to an error.
ds2psf_exe--ERROR: Cannot access file /root/simulation/example/ADSsim/schematic/netlist/data.ds.
\nds2psf was unsuccessful. PSF files are not available for this simulation.
----------The end of message----------------------------------------------------

plz tell me a solution. Thx~

Which syntax file do you use for device model, ADS or Spectre ?

I think you use ADS syntax device model file.
If so, change to ADS syntax netlist mode from Spectre syntax netlist mode.
