Problem to import HSPICE model into ADS

Hi,

I want to simulate the signal integrity of a gigabit tranceiver connection between two virtex 7 fpgas with Agilent ADS.
From our layout tool (Zuken) I get following HSPICE model of the board connection:

************************************************** **************************
* Netlist
************************************************** **************************

.subckt tmp_net tmp_in tmp_out


* Transmission line models
.model DSP1_RAM4_DQ W MODELTYPE=RLGC N=1
+ Lo=4.0055181e-007
+ Co=1.0270473e-010
+ Ro=6.9803922
+ Go=1.0732256e-011
+ Rs=0.001481472
+ Gd=1.0732256e-011


* Transmission lines

W_enet1:TL3 tmp_in GND tmp_out GND
+ RLGCmodel=DSP1_RAM4_DQ N=1 L=0.00070711

.end


This HSPICE model I want to import as a netlist into ADS. Following warning are displayed during reading the HSPICE model in ADS.

What is the reason for that? Does ADS don't understand the model typ 'w'?

Thank you in advance.

Kind regards
