Generation of the HDL-A-model of a micromembrane from its finite-element-description

A CAD tool for the automated generation of behavioral models in HDL-A is presented. This CAD tool has been implemented in the frame of a project for the automatic modeling of microsystem components for the co-simulation with VHDLor Spice-models. Starting from the finite-element-description of a microcomponent a nonlinear behavioral HDL-A-model is generated by successively adding or deleting effects to the HDL-A-model according to the observed differences between the two models. Using the example of a micromembrane the practicability of this approach is demonstrated. This CAD tool provides a method for decoupling the generation of behavioral models from the finite-element-simulation process.
