Fabian,

many models that are called 'Spice' are in fact PSpice models, just because
the former Microsim PSpice was (is) the most popular simulation tool. PSpice
uses some language extensions that are not compatible with generic Spice
simulators (eg. the VALUE statement). Protel uses the XSpice engine which is
an 'enhanced and extended version of Spice3'. But its backward compatible to
Spice, so you can use every 'real' Spice model.
