1u” steps the parameter X from 0.1u to 0.3u in 0.1u increments. 3u” steps the parameter X through each value listed.Įxample B: “.step param X. step command via a SPICE directive that specifies the steps for the parameter by a linear, logarithmic or list of values.Įxample A: “.step param X list. The addition of the curly braces around the variable is important as it tells LTspice IV that “X” is a parameter.

Define the component parameter with a variable by editing the component attribute (Ctrl–right-click on the component) and entering “” for the Value, where “X” is a user defined variable name.

To implement this in LTspice, perform the following steps: Here is an example waveform response of an RC circuit, for which the capacitance is stepped through three values.

step command causes an analysis to be repeatedly performed while stepping through a model parameter, global parameter or independent source.

step command to sweep across a range of values in a single simulation run. 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 Perform Repeated Analysis
