[Ngspice-users] model unrecognized parameters?

[David F. <fa...@cs...>]

Hi all,
	I'm trying to get a simple ring-oscillator example to work with
ngspice on Mac OS X.  (2005-04-21 CVS snapshot compiled and installed
cleanly, incidentally, with the tips from earlier posts.)  ngspice is
having trouble reading a model file with MOSFET parameters that I've
supplied.  In particular, it's dying on "unrecognized parameters (level)",
which I expected was a standard parameter.

In the example snippet: "ring/ring.spice" includes "018.mod".
Is there something elementary I've missed in the setup?  I'm almost
certain it's something simple... am I just using the wrong format?

Let me know if there's more you need to know about my setup.
Any help would be greatly appreciated, thanks!

David
