Full Package Signal Integrity Analysis
This article presents the use of CST MICROWAVE STUDIO® (CST MWS) for the simulation of large IC packages. From the time domain simulation network parameters can be extracted and further processed in CST DESIGN STUDIO™. Read full article..

Cadence® Allegro® Import in CST STUDIO SUITE™

Cadence® Allegro® Import in CST STUDIO SUITE™
An overview is given of the capabilities of the Cadence Allegro import feature in the CST STUDIO SUITE™. The user has full control over the layout export in Cadence itself and during the import process in CST STUDIO SUITE™. Cross-section and packaging export facilitites mean that layers, dies, and bond wires can be specified in the process. The imported structure is also subjected to an automatic cleaning and healing process to ensure an efficient simulation process. Depending on the size, complexity and required results, either the CST Time-Domain Solver or the Frequency Domain Solver may be used to establish the signal integrity of such layouts.

IC Package Simulation

IC Package Simulation
In this article the simulation of parasitic effects in a standard IC package is shown. The transient simulator in CST MICROWAVE STUDIO® (CST MWS) offers the advantage, that effects such as crosstalk and signal delay can be investigated in both time and frequency domain. Additionally, the simulation results can be used to generate an equivalent RLC network model that has the same S-Parameters as the 3D EM simulation but can be included in the overal circuit simulation of the logical parts of the IC.

Transmission Line Noise Source Simulation with CST MICROWAVE STUDIO®

Transmission Line Noise Source Simulation with CST MICROWAVE STUDIO®
This article demonstrates the simulatenous excitation of arbitrary waveforms at a number of different ports. A noise source in the form of a loop circuit is place above an IC package and the influence of the noise source on the transmission of differential signals in the IC feed tranmssion lines is investigated. Two frequency ranges were simulated, 1-10 GHz and 1-20 GHz. The simulations were carried out using the simultaneous excitation feature in CST MICROWAVE STUDIO® (CST MWS). Read full article..
