Description

technical field [0001] The invention relates to the technical field of integrated circuit full-wave IBIS model extraction, in particular to a field-circuit coupling-based integrated circuit full-wave IBIS model extraction method and device. Background technique [0002] The IBIS (Input / Output Buffer Information Specification) model is a fast and accurate modeling method for input / output (I / O: Input / Output) BUFFER based on the voltage / current (V / I) curve, which reflects the chip driver It provides a standard file format to record parameters such as drive source output impedance, rise / fall time, and input load. It is very suitable for calculation and simulation of high frequency effects such as oscillation and crosstalk. IBIS can be used to describe the behavioral characteristics of the input, output, and I / O Buffer of an IC device, and to simulate the interaction between the Buffer and the circuit system on the board.
