B.5 Additional Stepping Control Keywords

In contrast to the function-level discussed above, stepping can also be controlled at the overall level. In the Solve section, two keywords are provided:

Table B.6: General stepping control keywords.

Keyword	Type	Description
breakSteppingLoop	Boolean	break the innermost stepping loop
evalSteppingLoop	Boolean	evaluate the stepping only, do not simulate

The keyword breakSteppingLoop contains a condition for completely terminating the innermost stepping loop. For example, the stepping can be terminated if the drain current exceeds 500$\,$mA or if the cut-off frequency is already exceeded:

breakSteppingLoop = output("Device", "I", "DrainContact") > 5e-1 A;

frequency         = step(1 MHz, 6 GHz, 100 MHz);
breakSteppingLoop = !~Extern.firstStep && ~Curve.Response.beta < 1;

In order to evaluate the stepping functions only, the keyword evalSteppingLoop can be set. This flag allows a quick view on how the stepping functions work without starting the actual simulation. As there is no simulator information available, interactive features such as the conditional stepping cannot be tested.
