Today's defense systems are powered by secure electronics platforms and are more complex than ever. Sophisticated commercial electronics companies have evolved strategies to make sure their devices work correctly before building them. These strategies are now ready for the rigors of the Aerospace and Defense industry to bring advanced technology to the warfighter. You need to make sure all the high speed communication components will work as expected when they are integrated into the system. To do so requires accurate 3D modeling and electromagnetic and electro-thermal simulation at the chip, package, PCB, and system level. Making sure everything works as planned pre-fabrication can save substantial time in the project schedule.
