NEED HELP. Trans from HSPICE BSIM3v3 to ADS BSIM3v3 model

My foundry provides me a CMOS BSIM3v3 model file in HSPICE format.
In @DS, I transform it to a .net file, but in which there are some parameters ignored like:

LMLT
NDS
VNDS
CBD
CBS
FC
TT

I read elsewhere that using an ACM=2 Hspice uses improved MOS diode model. In my @DS netlist, ACM is take it into account and is set to 2, but for some reason @DS don?t uses the parameters above, so my question is:

1.- How to take into account theses parameters in @DS BSIM3ve model.
2.-The accuracy of my transient simulations will be decreased if i dont take into account these parameters?

P.D.
This is the HSPICE nmos end of the file where @DS could not make the translation of some parameters:

* *** Common extrinsic model parameters ***
+ACM =2
+RD =0.000e+00 RS =0.000e+00 RSH =7.000e+01
+RDC =0.000e+00 RSC =0.000e+00
+LINT =-5.005e-08 WINT =9.403e-08
+LDIF =0.000e+00 HDIF =8.000e-07 WMLT =1.000e+00
+LMLT =1.000e+00 XJ =3.000e-07
+JS =1.000e-05 JSW =0.000e+00 IS =0.000e+00
+N =1.000e+00 NDS =1000.
+VNDS =-1.000e+00 CBD =0.000e+00 CBS =0.000e+00 CJ =9.400e-04 CJSW =2.500e-10
+FC =0.000e+00 MJ =3.400e-01 MJSW =2.300e-01 TT =0.000e+00
+PB =6.900e-01 PHP =6.900e-01

I need help please, thank you!
