IE3D is an integrated full-wave electromagnetic si

2、mulation and optimization package for the analysis and design of 3D and planar microwave circuits, MMIC, RFIC, RFID, antennas, digital circuits and high-speed printed circuit boards (PCB). Since its formal introduction in 1993 IEEE International Microwave Symposium (IEEE IMS 1993), the IE3D has been

3、 adopted as an industrial standard in planar and 3D electromagnetic simulation. Much improvement has been achieved in the IE3D since then. The IE3D has become the most versatile, easy to use, efficient and accurate electromagnetic simulation tool. The following chapters provide a tutorial on using t

4、he IE3D 12 package. The focus is on the polygon based layout editor MGRID, object based schematic-layout editor IE3DLIBRARY, the integrated circuit simulator MODUA, and the pattern display post-processor PATTERNVIEW.From IE3D 11 to IE3D 12, we have seen much improvement on IE3D. One of the most impo

5、rtant improvements is the introduction of Automatic Geometry to IE3D Flow (AGIF). AGIF contains the Automatic GDSII to IE3D Flow allowing users to create complicated planar and 3D structures from layouts in GDSII format. It also contains the Cadence Virtuoso to IE3D Flow for RFIC designs, and Cadenc

The EMSocket allows users to run IE3D simulations seamlessly inside MWO. It combines the ease of use of MWO and powerful EM capabilities

8、of IE3D. The EMSocket is much improved on the IE3D 12.In IE3D 11.5, we have introduced the IE3D Full-wave Accelerated Simulation Technology Algorithm (FASTA). IE3D FASTA allows IE3D to simulate generally large structures using significantly reduced RAM and in a fraction of the time for the original

9、IE3D simulations. IE3D FASTA preserves the full-wave feature of IE3D while it reduces the computational efforts significantly with slightly reduced accuracy.Recent advancement in microwave, wireless, RF and semiconductor technologies require EDA imposes new challenging to circuit designers. New deve

The FastEM Design Kit allows users to get high accuracy full-wave designs done in real-time at design time. It signifi

It supports multi-CPU and multi-core computers. Full-wave EM tuning, optimization and synthesis require users to parameterize structures. To

12、 simplify the parameterization process and enhance the capability of parameterization, we have further improved our schematic-layout editor, or the IE3Dlibrary. We have introduced equation-based geometry modeling in IE3Dlibrary 11.x. Now, we introduce Boolean objects and void objects to allow parame

On IE3D 12, we have implemented automatic extraction and optimization of lumped circuit equivalent circuit fro

14、m IE3D simulations. The feature makes IE3D very handy for RFIC designers.This manual mainly serves as a tutorial manual. It demonstrates how the users can achieve the design goals thru many examples. Before we start the actual examples, we will provide a brief introduction in the theory. For those u

15、sers we do not want to know the theoretical part of the IE3D, they can skip Section 1 to Section 3 of this chapter. In fact, we also suggest those users who do not have much numerical simulation experience to delay reading the following sections until they get more knowledge from the next a few chap

16、ters.Section 1. Basic Theory and Implementation.IE3D is a full-wave electromagnetic solver. It solves the Maxwell Equations, which govern the macro electromagnetic phenomenon. There is no much assumption involved except the numerical nature of the method. Therefore, the solution is extremely accurate. The original Maxwells Equations are in differential form and the solutions of the equations are the electric field and magnetic field in the whole space. The solutions in
