EMI Software Simulation and Circuit
Modeling Services
Elite Electronic Engineering offers consulting services using
leading edge EMI computer simulations to model electromagnetic
emissions from printed circuit boards (PCB). These services
provide manufacturers with many advantages:
- Simulation provides design insight and focuses attention
on circuit elements that may cause non-compliant testing.
- Manufacturing costs associated with fabricating multiple
iterations of the PCB are reduced. This is because the PCB
is optimized as a "virtual board."
- Development time is reduced because virtual design iterations
are quickly generated.
- Design modifications are performed in a virtual environment
that easily facilitates "what-if" analysis.
- Compliance test services and retesting costs are reduced.
The simulations are performed by Elite simulation consultants
working with sophisticated software. Good EMI modeling requires
communication and interaction between the product developers
and the EMI simulation software consultant throughout the process.
These simulations are most cost effective when applied early
in the product design phase. As a robust simulation model emerges,
design modifications and board layout changes are easily implemented
to determine the optimum configuration.
Elite utilizes Omega PLUS, the Signal Integrity and EMI simulation
software platform from Quantic EMC Inc. Omega PLUS provides
all the tools to evaluate SI/EMI performance, crosstalk, ringing,
overshoot, undershoot, settling time, and noise margin violations.
Omega PLUS radiated emissions modules predict near-field EMI
levels from tracks, vias, and pins, even if the board is encapsulated
in copper planes.
Source suppression is applied as necessary.
Component models are typically acquired as IBIS or SPICE models
from the component manufacturer. If data is not available from
the supplier, the Omega PLUS Phidias behavior modeling tool
is used to generate V-I curve simulation models. Elite experts
work with the product designer to determine the viability of
component models, and where necessary, Elite will develop the
component model directly.
Elite SI/EMI software modeling is performed by consultants with
a proven track record of success using modeling techniques and
with the Quantic EMC platform. In addition to expertise with
the software, our consultants have an extensive background with
EMI testing, simiconductor modeling, electrical safety consulting,
and regulatory requirements.
