Turning Signal Integrity Simulation Inside Out: Page 2 of 2

Dr. Zoltan Cendes, one of the biggest names in electromagnetic simulation, says its time for design engineers to take a new approach.

same. The software knows the same geometry, but the encryption allows everything inside your device to be completely hidden from third party individuals.”

The advantages of physics-based simulation also extend beyond EM. Cendes' company, Ansys, believes thermal stimulation will be the next logical step. "[With physics-based simulation] you have the ability to solve integrated electro-thermal design and do electro-thermal mechanical verification,” he said. “You do an EM solution, then you get loses from currents (meaning heating) that gives you the power that's fed into the thermal solver. [The thermal solver] gives you the temperature distribution. You can then feed that into the mechanical solver where the thermal effects on stress can be analyzed. And it can all be done in the same interface.”

Much like the people on the Li River transitioned from fishing to digital photography, Cendes imagines inside-out simulation having a similar revolutionary impact on design flow. He told the DesignCon audience it only makes sense as electronic devices become more and more integrated into our day-to-day world. “The world is physical, EM simulation needs to lead the way, with the circuit and system models driving electromagnetics and not the other way around.”
