CST Announces Integrated Workflow
For Signal Integrity Analysis
Santa Clara, Calif., February 3rd 2009, Computer Simulation Technology (CST) announces the
integration of cable, PCB, and EMC/EMI simulation in CST STUDIO SUITE 2009 at DesignCon, booth
#315.
Design engineers and researchers working on the signal integrity of complex systems containing cables,
PCBs, and fully three-dimensional passive components, will benefit from the latest release of CST STUDIO
SUITE. Highly specialized tools such as CST PCB STUDIO (CST PCBS) and CST CABLE STUDIO (CST CS)
are used to study signal propagation on PCBs and cable harnesses, with high efficiency. These tools are
part of CST DESIGN ENVIRONMENT, which also provides access to the market leading time domain solver
CST MICROWAVE STUDIO® (CST MWS), for the optimization of full 3D components with respect to signal
integrity. The entire system can then be synthesized in CST DESIGN STUDIO (CST DS) which is also used
to access and modify the individual components of the system.
Signal currents can be used in CST MWS as excitation sources for EMC/EMI analysis. Through this highly
integrated workflow, SI and EMC issues can be addressed early in the design process, reducing the number
of expensive cut and try iterations.
“CST’s customers have always valued our user-friendly interfaces with industry leading EDA tools,”
commented Dr. Martin Timm, Marketing Director, CST. “We now additionally provide a streamlined
workflow which comprises the analysis of not only individual components, but also the entire system as
well as the resulting EMC/EMI effects.”
CST PCB STUDIO
CST PCB STUDIO (CST PCBS) is a specialist tool for the investigation of Signal and Power Integrity and the
simulation of EMC and EMI effects on Printed Circuit Boards (PCB). Applications include high speed digital,
analog/mixed signal, and power supply. CST PCBS seamlessly integrates into various design flows,
calculating parasitic crosstalk effects and simulating the electronic network in time or frequency domain.
Of particular interest is the interface with CST MICROWAVE STUDIO® (CST MWS) which enables linking PCB
simulations with subsequent full 3D analysis of electromagnetic emissions.

CST CABLE STUDIO
CST CABLE STUDIO (CST CS) is focused on the analysis of SI, EMC and EMI effects in cable harness
systems. Applications include the optimization of shielding, weight and space consumption on single
wires, twisted pairs, and complex cable harnesses with an unlimited number of cables. Typical analyses
include voltage distributions on probes, current flow through components, scattering parameters,
impedances, and emissions simulation through CST MWS.
Availability
Both tools are available in CST STUDIO SUITE 2009.
About CST
CST develops and markets high performance software for the simulation of electromagnetic fields in all
frequency bands. Its success is based on the implementation of unique, leading edge technology in a user-
friendly interface. CST’s customers operate in industries as diverse as Telecommunications, Defence,
Automotive, Electronics, and Medical Equipment, and include market leaders such as IBM, Intel,
Mitsubishi, Samsung, and Siemens. With 160 employees worldwide and a network of qualified distributors,
over 190 people are dedicated to the development and support of its EM products in more than 30
countries.
CST’s flagship product, CST MICROWAVE STUDIO® (CST MWS) is the market leader in Time Domain
simulation. It enables the fast and accurate analysis of high frequency (HF) devices such as antennas,
filters, couplers, planar and multi-layer structures and SI and EMC effects. CST MWS offers considerable
product to market advantages such as shorter development cycles, virtual prototyping before physical
trials, and optimization instead of experimentation.

“A complex system containing cables, PCBs, and connectors: the signal propagation of the respective
parts was simulated using CST CABLE STUDIO, CST PCB STUDIO and CST MICROWAVE STUDIO® (CST
MWS) and the results were combined within CST DESIGN STUDIO. EMC/EMI analysis of the system,
including housing, was performed using CST MWS.”
