Example 18—Numerical Integration: TRAP versus GEAR<br />

average value. Sometimes even high accuracy and limitation of the timestep cannot totally<br />

prevent these numerical oscillations. In these cases, switching to the GEAR method is a possible<br />

remedy.<br />

Summary of Eldo commands used in this example:<br />

• .ALTER—Simulation rerun.<br />

Netlist Explanation<br />

.alter<br />

.option gear<br />

The above lines rerun the same simulation using GEAR method instead of the default TRAP<br />

method.<br />
