My foundry provides me a CMOS BSIM3v3 model file in HSPICE format.
In ADS, 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 ADS netlist, ACM is take it into account and is set to 2, but for some reason ADS don’t uses the parameters above, so my question is:
1.- How to take into account theses parameters in ADS 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 ADS 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!
