Abstract

Now a number of models can be applied to the signal integrity analysis, including: IBIS (and its expansion – EBD), MOD (and expansion of this model – PML), SPICE. IBIS models found application in many systems of design, in particular, of P-CAD 200x, Altium Designer, Mentor Graphics HyperLynx and in others. Application of IBIS models allows to bypass the difficulties connected with creation and application of SPICE models of the integrated circuits which are based on the detailed description of internal structure of a product. In this work we discuss experimental methods of IBIS models creation. The main attention is paid to interpretation of measured I-V curves of digital integrated circuits input and output buffers. The basic structure of the output CMOS buffer of the digital scheme is the basis for IBIS model. One of the most difficult stages upon termination of physical measurements include the obtaining the corrected dynamic characteristics for creation of IBIS model. Along with simulations, the experimental methodology can significantly reduce complexity and time for IBIS models generation.
