IBIS models provide a standardized way of representing the electrical characteristics of a digital IC’s pins (input, output, I/O buffers and the like) behaviorally, i.e., without revealing the underlying circuit’s structure or process information.

2015年9月11日 · 2 and 3 contain general information about the IBIS versions and the general rules and guidelines. Several progressions of IBIS documents are referenced in Section 2 and in the discussion below. They are: • IBIS Version 1.1 (ratified August 1993) • IBIS Version 2.1 (ratified as ANSI/EIA-656 in December 1995)

IBIS 模型是最常见的板级信号完整性仿真模型,本文将介绍如何创建IBIS模型。 IBIS 是I/O Buffer Information Specification 的简称,即基本的输入/ 输出缓冲器信息规范。 和常见的HSpice和Spectre 等晶体管级(物理级)缓冲器模型不一样,IBIS 只是描述了IC 的输入、输出或IO缓冲器的行为级电气特性,并不涉及缓冲器的底层结构和工艺信息。 本文将介绍如何获取创建IBIS 模型所需的信息,并避免创建IBIS模型时一些常见的错误。 本文假定读者有一定的SI 基础,了解IBIS 模型规范,也熟 …

IBIS (I/O Buffer Information Specification) is a Behavioral Modeling Specification that is gaining world wide popularity as a standard format to generate device models. IBIS solves many of the problems that prevented system designers from obtaining semiconductor vendor’s SPICE models.

本文提供有关在创建IBIS模型时如何使用LTspice®的说明指 南，涵盖从IBIS预建模程序到IBIS模型验证的整个过程。本文 还详细介绍如何在LTspice中为IBIS模型准确提取I-V、V-T、斜坡 和C_comp数据。此外，还提供定性和定量FOM方法，用于验证 IBIS模型的性能。

TI 正在开发一套新的数字输入/输出缓冲器信息规范 (IBIS) 仿真模型,旨在满足各种客户需求。 这种模型(请参见图 1)可用于仿真环境中,帮助解决诸如板级过冲、欠冲或者串扰等问题。 在更基础层面,IBIS 模型提供了一些有用的产品信息,例如:引脚电容及寄生效应或者数字输出缓冲器的升/降时间。 本文即系列文章之第 1 部分(共 3 部分)介绍了 IBIS 模型的一些基本组成及其在 SPICE 环境中生成的过程。 第 2 部分将研究 IBIS-模型验证。 第 3 部分将介绍 IBIS 用户如何研究信号完整性问 …

IBIS is an acronym for “I/O (Input-Output) Buffer Information Specification.” It is a template (standard, data-exchange format, etc.) for exchanging modeling information between semiconductor device suppliers, simulation software suppliers and end users of this information.

2023年5月30日 · IBIS模型是一种基于V/I曲线的对I/O 缓冲器快速准确建摸的方法,是反映芯片驱动和接收电气特性的一种国际标准,它提供一种标准的文件格式来记录如驱动器输出阻抗、上升/下降时间及输出负载等参数,非常适合做振铃( ringing) 和串扰(crosstalk) 等高频效应的计算与仿真。

2022年12月7日 · IBIS models are a compact and secure standard for simulating oscillators within a larger circuit. System-level designers looking to simulate oscillator performance can utilize IBIS models provided by Abracon to simplify and expedite the design process.
