No wonder one of the late, great analog gurus did not think Spice was the end all of simulation. You know, the one who eschewed seat belts. Look at this article which compares the models put out by two major semiconductor manfacturers. https://www.google.com/url?sa=t&rct...0eQZpzh2vZ8bB8_OD10hu3g&bvm=bv.53537100,d.aWc .
Then you can read articles that denigrate the models commonly used. https://www.ele.uri.edu/Courses/ele443/tutorials/q2n3904.model/
So I compared three simulators using a two transistor amplifier, and got differences in voltage and currents at the component terminals. The results were not grossly different, but I wonder why those folks cannot agree on what a particular model should be, even if they cannot make a transistor that copies it very well.
