Re: gEDA-user: using TI spice models



Another way to check your results is to read your netlist into LTSpice
and/or Gnucap and run your sim using it.  Indeed, since Gnucap is a
completely different simulator, comparing ngspice to Gnucap is a good
robustness test.  If you get same result (likely), then the problem is
your circuit, not your sim.
