Simulation in Hardware Design and Testing

Hardware description languages(hdl s)have been used in industry since the1960s to document and simulate hardware designs.Simulation of hdl descriptions is very useful to ?nd design faults without the need to manufacture the design.A well known drawback of simulation,however,is that the numbe

Ranking Reflecting on the simulation exercise, we have made both correct and incorrect decisions. Nevertheless, although we ranked 4th (Exhibit 1: OVERALL TEAM STANDING), we believe we gained a deeper understanding of queuing theory and have obtained invaluable experience from this exercise.

SolidWorks Simulation图解应用教程（五）

在实际工程设计中，各种机器设备和工程结构都是由若干个构件组成的。这些构件在工作中都要受到各种力的作用，应用静力学的知识，我们可以分析计算这些构件所受到的外力情况。为保证机器设备和工程结构在外力作用下能安 全可靠地工作，就必须要求组成它的每个构件均具有足够的 承受载荷的能力。

在实际工程设计中，各种机器设备和工程结构都是由若干个构件组成的。这些构件在工作中都要受到各种力的作用，应用静力学的知识，我们可以分析计算这些构件所受到的外力情况。为保证机器设备和工程结构在外力作用下能安 全可靠地工作，就必须要求组成它的每个构件均具有足够的 承受载荷的能力。 通过材料力学的知识，研究构件在外力作用下的变形、 受力和破坏的规律，保证构件能够在正常、安全的工作前提下 最经济地使用材料，为构件选用合理的材料，确定合理的截面形状和尺寸。为了保证工程结构在载荷作用下正常工作，要求每个构件均具有足够的承受载荷的能力。下面我们用横梁的力学研究来展示实际分析过程(这里仅介绍分析的方法，所有的数据均是假设)。 1.新建图1所示零件

Cadence仿真介绍

第一部分：仿真流程

第二部分：IBIS模型

IBIS模型和SPICE模型比较： SPICE模型：

（1）电压/电流/时间等关系从器件图形、材料特性得来，建立在低级数据的基础上 （2）每个buffer中的器件分别描述/仿真 （3）仿真速度很慢

（4）包含芯片制造工艺信息 IBIS模型：

（1）电压/电流/时间关系建立在IV/VT数据曲线上 （2）没有包括电路细节

（3）仿真速度快，是SPICE模型的25倍以上 （4）不包含芯片内部制造工艺信息

基于上述原因，对于在系统级的设计，我们更倾向于使用IBIS模型。目前IBIS主要使用的有V1.1，V2.1，V3.2及V4.0等版本。模型结构如下图：

C_pkg，R_pkg，L_pkg为封装参数；C_comp为晶片pad电容；Power_Clamp，GND_Clamp为ESD结构的V/I曲线。

输出模型比输入模型多一个pull-up，pull-down的V/T曲线。

Cadence的model integrity工具负责对IBIS模型进行语法检查、编辑以及进行DML格式转换。Cadence仿真不直接使用IBIS模型，而必须先把IBIS转换成DML。
