Reliable CAD interfaces reduce the amount of modeling required for existing structures, and are a useful tool for reducing the design engineer’s workload. The CST Studio Suite® is renowned for its excellent CAD-data import capabilities and the sophisticated healing mechanisms which recover the integrity of flawed or non-compliant data. The latter aspect is particularly vital as the presence of one corrupted element can prevent the usage of the whole part.
The IC package example on the right was provided as a Cadence® Allegro® layout with 8 metallization layers and a total of 40,000 geometrical entities. The proprietory Cadence Allegro interface provided robust data exchange including automatic model clean-up. This model clean-up is essential to reduce the model complexity and to facilitate the simulation.
With CST Studio Suite, models from SOLIDWORKS 2013 and PTC Creo™ Elements™ 5.0 (Pro/E) can be imported in fully parameterized format. The bidirectional link between CAD and simulation allows design changes to be instantly reflected in the simulation model, and means that the results of optimizations and parametric design studies can be imported back directly into the master model. This improves workflow integration and reduces the time and effort needed to optimize a design.
