CST與主流軟件的協同——CST之接口綜述

---

CST設計環境是一個開發平臺，具有廣泛的互通性，提供了大量的與業界知名軟件的接口，包括結構、Layout、SI
、SPICE、IBIS、SAR等，以下介紹CST2009版的各種接口。
圖1中，Simlab是我們的戰略合作伙伴、Gerber是應用于板級的、Nastran是建模用的、Cadence Allegro是大名鼎
鼎的EDA軟件、PRO/E Wildfire 3、CATIA V5 R17以及Autodesk Inventor 11都是CST可以吃進的CAD格式。

圖1
單箭頭指向CST的表示CST可以導入該種格式，單箭頭指出表示CST可以導出該種格式，而雙箭頭表示CST即可以導
入，也可以導出該種格式。
圖2中，IBIS導入是應用于板級仿真的，Mentor Graphics Expedition、Zuken CR 5000等都是PCB板的各種格式，CST都與它們之間有著相應接口。

以上是CST2009版中各種豐富的接口，也許介紹地還不是很全，給大家一個大致印象，歡迎大家補充。如果有說錯
的地方也歡迎大家指出，討論。∩_∩

5樓、6樓的資料是哪來的?這么全啊。CST的FANS還是CST的用戶啊

cst可以跟ads協同嗎?

cst用起來真的很順手，復雜的在cad里畫好導入就ok了，爽哉！

呃，看來又要學習一種新軟件了。

我也想知道

cad一般都是二維圖，cst 可以導入它的三維嗎?
我跟你正好相反，我是用仿真軟件建模仿真，然后導入cad里邊做圖標注加工的~

純粹就使用來講（兩個軟件對不同的問題，都有自己的長處），HFSS還是更方便，尤其是后處理。另外，CST集成這么多功能，導致使用很不穩定，好像集成并不好.

學了一陣子就懶下來了誒恒心毅力啊

功能越來越強大了
支持個。
