CST与主流软件的协同——CST之接口综述

CST设计环境是一个开发平台，具有广泛的互通性，提供了大量的与业界知名软件的接口，包括结构、Layout、SI
、SPICE、IBIS、SAR等，以下介绍CST2009版的各种接口。
图1中，Simlab是我们的战略合作伙伴、Gerber是应用于板级的、Nastran是建模用的、Cadence Allegro是大名鼎
鼎的EDA软件、PRO/E Wildfire 3、CATIA V5 R17以及Autodesk Inventor 11都是CST可以吃进的CAD格式。

图1
单箭头指向CST的表示CST可以导入该种格式，单箭头指出表示CST可以导出该种格式，而双箭头表示CST即可以导
入，也可以导出该种格式。

图2中，IBIS导入是应用于板级仿真的，Mentor Graphics Expedition、Zuken CR 5000等都是PCB板的各种格式，CST都与它们之间有着相应接口。

5楼、6楼的资料是哪来的?这么全啊。CST的FANS还是CST的用户啊

cst可以跟ads协同吗?

cst用起来真的很顺手，复杂的在cad里画好导入就ok了，爽哉！

呃，看来又要学习一种新软件了。

我也想知道

cad一般都是二维图，cst 可以导入它的三维吗?
我跟你正好相反，我是用仿真软件建模仿真，然后导入cad里边做图标注加工的~

纯粹就使用来讲（两个软件对不同的问题，都有自己的长处），HFSS还是更方便，尤其是后处理。另外，CST集成这么多功能，导致使用很不稳定，好像集成并不好.

学了一阵子就懒下来了诶恒心毅力啊

功能越来越强大了
支持个。
