AWR SIGNAL INTEGRITY™ DESIGN SUITEOverview + 9I|Fm

The AWR SI design suite is a natural extension of the company's flagship Microwave Office® design suite into the realm of high-speed digital applications. At today's high data rates, digital signals deviate from the "norm" and become analog in nature. The Signal Integrity design software addresses the high-frequency nature of these high-speed designs. The software is targeting highly integrated co-chip/package/module designs as it specifically addresses the complex cross-domain signal integrity issues inherent in today's Gbps data rate products.

AWR's AXIEM electromagnetic (EM) software GYg.B<Q.  
http://web.awrcorp.com/Usa/Products/AXIEM%2D3D%2DPlanar%2DEM/ )HcLpoEi  
Overview vjzG H*  
AWR's AXIEM electromagnetic (EM) software is an industry first to deliver EM analysis as a true upfront design technology. Its speed, capacity and accuracy benefit designers most by helping to diagnose issues early, thereby significantly shortening the design process. The AXIEM product was developed specifically for three-dimensional (3D) planar applications such as RF PCBs and modules, LTCC, MMIC, and RFIC designs. 6L;]5)#

一个偏数字，一个偏模拟 看起来是这样

我的感覺好像不是這樣，因為我手上沒這些工具，也沒實際用過 AWR 的產品的經驗。 $3l#eKZA  
能否用更深入的角度來探討這兩個工具，Like 數值的方法的角度，或是他的極限等等。

我用 awr ， 新的 8.0版本 有了 AXIEM ， 我感觉他很像 一个 在某些方面特殊增强的一个 2.5D的 仿真软件。 增强的地方比如 cmos里面的 厚金属线的处理等。 mXJG &EA  
awr 原来有 EMsight 作为 EM的仿真引擎，现在又多了一个强化版本而更有效的引擎AXIEM。 gPKO-Fsd"

而 SI 从附上的文档看，我感觉它就是 awr ，没有什么大区别。 可是看来又是一个独立出来的产品，所以check了一下官方的信息 /。 }W " i{s/

我没有对  axiem做过很多的 比较标准的测试，用它仿真过，平面的准确度倒是还不错。不过说实话速度上都不如IE3D，不过有些优势的就是他 集成在 AWR 里面，可以进行电路联合仿真和优化。这一点有时候是有优势的。
