IBIS Modeling
Many manufacturers now provide interface models in IBIS format, a kind of behavioral modeling language that describes the I/O pin interface in terms of impedance and timing. Micro-Cap translates these IBIS models into useable SPICE models which accurately reproduce the calibration waveforms (Golden Waveforms). The increased accuracy of the buffer models greatly simplifies board testing. New to MC9, the IBIS components simplify selection and testing of IBIS modeled parts.
