LTSPICE2MATLAB imports an LTspice IV

LTSPICE2MATLAB imports an LTspice IV .RAW waveform file containing data from a Transient Analysis (.tran) or AC Analysis (.ac) simulation, and converts voltages and currents vs. time (or frequency) into a Matlab data structure. This function can read compressed binary, uncompressed binary, and ASCII file formats. In the case of compressed binary, the data is automatically uncompressed using fast quadratic point insertion. This function handles very large binary simulation files efficiently, and has an option to load only a subset of a file's waveforms to reduce memory consumption. Type >> help LTspice2Matlab for details.

Use LTSPICE2MATLAB to import LTspice waveforms for additional analysis in Matlab, or for comparison with measured data. LTspice2Matlab has been tested with LTspice IV version 4.01p, and Matlab versions 6.1 and 7.5., and regression testing has been used to expose the function to a wide range of LTspice settings.

Note: LTspice IV is a Spice III simulator and schematic capture tool freely avaliable for download at www.linear.com/designtools/software. It is optimized for simulation of switching regulators, but can simulate many other types of circuits as well and comes with a variety of component models.

System Requirements:

MATLAB 6.1 (R12.1)
