Curve Fitting Feature Enables Measurement Based Electrical Models

The Bode Analyzer Suite, starting with version 3.50, includes an advanced SPICE modeling feature. Download the software here: https://www.picotest.com/support/bode-100/

Now you can turn your test measurements into simulation models. This feature is available for BOTH the Bode 100 and the new Bode 500 VNA.

It’s quite amazing and as simple to use as is shown in the video. You test your component’s impedance in any suitable manner. Then you can fit the data with pre-programmed (i.e., simpler) templates or you can let the full power of the curve fitting software choose an arbitrary network, synthesized to your percent error and weighting. You can check the fit and when finished, a simple button click exports the SPICE subcircuit netlist for use in your favorite simulation tool.

Benefits
• Quickly generate measurement-based models
• Produce electrical models for challenging circuit structures (cable assemblies, passive devices, filters, VRMs, source impedance, beads, black-box, etc.)
• Electrical network synthesis from test data
• Produce models for parts lacking manufacturer support
• Test – simulation waveform overlay shows instant accuracy/error of the fit

Features
• SPICE Model generation from test data
• Exports SPICE 3 compatible subcircuit netlist ready for use with any simulator
• Curve fitting with various circuit template structures – more useful for tolerancing
• General curve fitting algorithm for more accuracy - up to 20 poles
• Passivity option eliminates negative values
• User-defined % target error (Root mean squared error)
• Various weighting options
• Graphical display of test result, simulated waveform, and error
• SPICE model re-import for further optimization
• Series or Shunt synthesis option
• Laplace equation display
