Are there any semiconductor vendor-supplied models in IC stream?

achilles

I am thinking these files contain standard models; how do we know the names of the models included? and how do we use them? 

cmi.pic.o  libphilips_sh.so  libinfineon_sh.so  libstmodels_sh.so  libsparam_sh.so  defaultConfig

 Thanks,

     Just for completeness, if you do "spectre -h" you'll see a bunch of available components listed with a "*" next to them. For example:

         bjt301*          bjt500*          bjt500t*         bjt503*
        bjt504*          bjt504t*         bjt3500*         bjt3500t*
        bjtd504*         bjtd504t*        bjtd3500*        bjtd3500t*

    These come from the shared libraries you've listed. The idea is that the code which defines the model equations can be loaded via a shared library. This is used by some customers to add custom models (via the C Model Interface) into spectre and other Cadence simulators. There are also some models which aren't listed in the spectre -h which come from these.

    However, the key thing is that this is just the model code - not the model parameters. To use these models for a real process, you'd need a model card which will define appropriate sets of parameters to represent the measured and qualified behaviour of a real device, as Bernd said.
