The IBIS2Spice Converter generates SPICE models from an IBIS (I/O Buffer Information Specification) model file. IBIS models provide nonproprietary information about I/O buffers that are used to characterize I/V output curves, rising/falling transition waveforms and package parasitic information for a variety of digital devices. IBIS only exposes tables of data for device I/O pins, while the generated SPICE model in turn produces corresponding piecewise linear signal representations.

To generate SPICE models from an IBIS file, the user simply browses for the file and clicks the "convert" button. All models are then quickly converted to accurate SPICE models for typical, best-case and worst-case process corners.
