Intusoft's IBIS2SPICE converter is the only product of its kind offered by a SPICE-simulation vendor. IBIS is a modeling technique that provides a simple table-based buffer model for semiconductor devices. 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.

IBIS2SPICE supports all 14 IBIS model types, and converts IBIS models up through version 3.2. To generate SPICE models from an IBIS file, the user simply browses for the file and clicks the "convert" button. All devices are then quickly converted for typical, best-case and worst-case process corners. SPICE models are generated for Input, Output, I/O, 3-state, Open-Source, Open-Drain and other I/O structures. The models can be easily added to the part browser inside of Intusoft's ICAP/4 "SpiceNet" design entry system.

IBIS2SPICE is included free of charge with the following software packages: Test Designer, ICAP/4 Professional, ICAP/4Windows Power Deluxe, ICAP/4Windows RF Deluxe and ICAP/4Windows. IBIS2SPICE-S is a purchasable standalone version.
