There are two ways to examine a circuit in LTspice by changing the value for a particular parameter: you can either manually enter each value and then resimulate the circuit to view the response, or use the .step command to sweep across a range of values in a single simulation run.The .step command causes an analysis to be repeatedly performed whil Next step is to simulate the circuit. ltspice. The DC sweep allows you to do various different sweeps of your Circuit to see how it responds to various conditions. For all the possible sweeps voltage, current you need to specify a start value, an end value, and the number of points you wish to calculate. An optional second source can also be used to run a nested sweep. The DC Sweep analysis generates output like that of a curve tracer.
