Visualizations are a crucial component in CAD systems, typically displaying design layout or physical behavior. In this paper we introduce in an innovative way visualizations, that combine both, the display of physical n and abstract concepts. These types of visualizations are part of MAGDA a CAD system for Micro Electro Mechanical Systems (MEMS). In MAGDA we display the geometries of the device as it is being designed, and the resulting reliability, an attribute that is in part, affected by those geometries. The reliability visualizations are a powerful contribution to working faster towards a robust design, reducing the trial and error phase in the design.
