HANDLING MODEL SIMULATION FAILURES
Subcircuit models vary greatly in complexity and design. As a result, some models are
easier to simulate than others. As a general rule, if PROSPICE could not simulate your
circuit with its translated model, then not much else could either.
We have often found that problems are greatly worsened by poor circuit design. If you have
an application note for the device, then compare it with your circuit to see if, for example,
you are not allowing enough input current to bias the input stage successfully. The model
designer almost certainly made the model work with circuits similar to those in an
application note, rather than in a general case.
PROSPICE can be made more stable (but less accurate) by increasing the value of GMIN.
The default is 1E-14, so good values to try are 1E-13 and 1E-12. At values like 1E-6, it is
likely that any simulation results will bear no relation to reality at all, so pick the lowest
value you can.
