Parse Spice Simulation Output With Python

Python modules like Pandas, Anaconda and SciPy offer great possibilities to work with large numerical data sets. These possibilities to manipulate numerical data can do a great job for analyzing Spice simulation results.

BeSpice Wave Parser, our waveform parser library has been extended to a Python module with the complete functionality of the C/C++ interface. This allows engineers to directly access and read the files generated by Spice simulators from Python. Many different binary and ASCII file formats such as PSF, PSFXL, … are supported. The files can be read and re-read while the simulation is still in progress. For binary files only the required data is read into memory.

BeSpice Wave Parser also allows to export the parsed data to other file formats. Our Python modules are compatible to Python 2.7 and 3 and available on Linux and Windows. We provide a set of examples that presents the complete functionality.

BeSpice Wave Parser is also available as Matlab/Octave toolbox or with a Tcl/Tk wrapper.
