level=54 is the HSPICE level number for bsim4. Most likely your model files are in SPICE syntax.
I can't test, because I no longer have an IUS54 installation. However, IUS55 was using 6.0.1 so was a pretty old version of spectre. I think in IUS54 the new SFE (Simulation Front End) was either not on by default or not on at all.
I did locate an IUS54 installation after all, but see that it was before the print_mmsimver command, so it's clearly pretty old. It was released in 2004, compared with MMSIM62 which was 2007.
Fundamentally you need to use a more recent version of IUS which supports the newer simulator front end. Trying to simulate 45nm models with a 5 year old simulator is asking for trouble, I'm afraid, even if the parser had worked - there are inevitably going to be fixes you should be using, especially in AMS which has evolved. Your IC build is a similar vintage to the MMSIM62, but the IUS is considerably older...
Regards,
Andrew.
