Innovation and collaborative, synchronized program management for new programs
WILSONVILLE, Ore., Nov. 12, 2015—Mentor Graphics Corporation (NASDAQ: MENT) today announced the newest version of its market-leading FloTHERM® product, the industry’s most powerful and accurate computational fluid dynamics (CFD) software solution. The FloTHERM product was developed to quickly identify potential thermal issues early in the design process to avoid expensive late stage re-design and warranty costs arising from thermal failures in the field. The newest version of the FloTHERM product delivers an automated method to calibrate simulation models to match transient thermal measurements recorded with the Mentor Graphics® T3Ster® hardware. As a result, the FloTHERM product can help maximize simulation data accuracy and provide additional insight into product reliability – a necessity for the automotive, aerospace and electronics products industries.
Mentor Graphics T3Ster product is an advanced thermal tester for thermal characterization of IC packages, LEDs and systems which produces extensive thermal characteristics rapidly. The industry-leading T3Ster test system delivers highly accurate, real-time measurements of heating and cooling transients based on its advanced implementation of the JEDEC static test method (JESD51-1) and can now be considered to be 10X better than alternative solutions.
The new FloTHERM product can convert a simulated transient thermal response into a structure function curve using the same mathematical process utilized by the T3Ster product. These structure function curves are known to correlate with the physical structure of the device, and are thus the ideal platform to compare simulation with test data. Differences between the structure functions indicate that some aspect of the simulation model is incorrect; typically dimensions or physical properties that are difficult to measure directly such as thermal interface material (TIM) thicknesses or interfacial thermal contact resistances. The new FloTHERM version uses optimization methods to change the model inputs and drive the simulation structure function towards the experimental structure function until a match is achieved. This match indicates that the FloTHERM model is fully calibrated and will respond correctly and accurately in any transient application. Package manufacturers can now certify supply chain models, by providing evidence about the thermal performance of the component in customer applications along with the model itself.
“Working with a fully-calibrated model of a package is often critically important in steady state and transient analyses when accurate prediction of the junction temperature is the objective,” said Ir. Clemens Lasance, principal scientist at Philips Research (retired) and consultant at SomelikeitCool. “The calibration is usually performed by creating a structure function to be compared with the one measured with a T3ster in the lab. The latest version of FloTHERM embeds an automated ability to fine-tune a FloTHERM model to achieve this match, making this best practice modeling methodology far more accessible to thermal engineers."
Additional features in the new FloTHERM product include:
“By using an uncalibrated model for simulation, manufacturers run the risk of simply guessing performance. Calibrating the package model constants ensures the product will respond accurately in all steady state and transient applications” stated Roland Feldhinkel, general manager of Mentor Graphics Mechanical Analysis Division. “We continue to invest in leading simulation and measurement technologies to provide our customers with superior and productive capabilities to handle their most complex thermal management challenges."
