[Help-gnucap] Support for BSIM models

I'm wondering if the latest gnucap (or earlier ones like 0.35) supports BSIM models we use at work in HSpice. The gnucap home page talks of supporting MOSFET level 1 to 8, and 49, models, which sound like early ones to me, although I'm not claiming to be any kind of a Spice expert. The latest gnucap announcement of development version 2008-08-10 indicates support for the BSIM462 model, which I guess is BSIM level 4.6.2, from the nomenclature on the BSIM Homepage (http://www-device.eecs.berkeley.edu/~bsim3/bsim4.html). The models I want to use have headers like:

*    PROCESS :  some process
*    MODEL   :  BSIM4/BSIM3 ( V2.0/V3.2.4 )
*    VERSION :  V1.4
*    DATE    :  August 20th, 2004
*    HSPICE VERSION : H2003.09

or


*    PROCESS :  process name
*    MODEL   :  BSIM4/BSIM3 ( V4.5/V3.2.4 )
*    VERSION :  V1.5
*    DATE    :  July. 30th, 2006
*    HSPICE VERSION : HSPICE  Y-2006.03

with a typical model content of:

.MODEL nch.1 NMOS ( LMIN = '1.0000E-05-dxln' LMAX = 2.001E-05 +WMIN = '1.0000E-05-dxwn' WMAX = 9.001E-04 LEVEL = 54
+VERSION  = 4.5                 BINUNIT  = 2                   PARAMCHK = 1
+MOBMOD   = 0                   CAPMOD   = 2                   IGCMOD   = 1
. . .
. . .


Should these work in gnucap? Thanks.
