Los Angeles, CA (August 2, 2005) - EMA Design Automation™, a full-service
provider of Electronic Design Automation (EDA) solutions, and AEi Systems, a world
leader in power electronics modeling and analysis, today announced the release of
the Power IC Model Library™. This PSpice® library incorporates over 150 time-domain
simulation models for power electronic designs and gives designers capabilities
previously unavailable for these popular parts — the ability to plug in a model,
representative of the actual IC, and simulate the switching performance under actual
operating conditions.
An important breakthrough for power engineers
“Many EDA vendors only have access to information in the data sheets, which is not
sufficient when modeling a controller or regulator,” stated Charles Hymowitz, Managing
Director of AEi Systems. “The data sheets simply do not have the level of detail
required, and companies who rely solely on data sheet input produce substandard
and inaccurate models.”
“AEi Systems has proprietary relationships with nearly all of the top analog IC
manufacturers. Those relationships give AEi access to the part characteristics needed
to produce models with the accuracy our customers expect,” stated Manny Marcano,
President of EMA Design Automation. “Because AEi Systems is the sole developer of
many Power IC models, this library contains parts that are not available from any
other EDA company. At $995 per user, the library is a tremendous value, since single
models can cost from $2,000 to $15,000 each to develop.”
Complex Models, Verified with Bench Data
SMPS applications today are much more demanding than ever. Today's designs require
increases in power IC functionality, switching frequency, and system interaction.
State space based models simply do not reveal many important nonlinear factors that
influence these performance characteristics. The models in this new model library
enable designers to perform high-speed, cycle-by-cycle simulations to show true
large-signal performance, simulate current-mode control using the latest accurate
modeling techniques, run CCM and DCM converter simulations, generate line and load
step responses, and measure power stage loss and stress analysis for all major components.
The models in the Power IC Model Library are compared and verified with bench data
under startup, steady state, line, and load transient conditions. Nonlinear characteristics
such as propagation delay, switching speed, drive capability, maximum duty cycle/current
limits, and startup phenomena are all accurately modeled. Designers can directly
compare the performance of components from various vendors and analyze the effects
of different implementations such as peak current mode control, hysteric current
control, low voltage, and low operating current, to name just a few.

The Power IC Model Library includes model netlists in PSpice syntax, schematic symbols
for OrCAD Capture® and a set of example application circuits for many of the IC
models.
More details are available at EMA, including a list of the components and documentation
detailing the models’ accuracy and performance.
