An acoustic resonator, comprises a substrate and a first passivation layer disposed over the substrate. The first passivation layer comprises a first layer of silicon carbide (SiC). The acoustic resonator further comprises a first electrode disposed over the passivation layer, a second electrode, and a piezoelectric layer disposed between the first and second electrodes. The acoustic resonator comprises a second passivation layer disposed over the second electrode. The second passivation layer comprises a second layer of silicon carbide (SiC).

A method for detecting and reporting changes in functional features of a simulation model caused by a software revision is disclosed. In one aspect, the method is independent of simulation model architecture. One performs regression testing with a plurality of feature-specific modules. The feature-specific modules are configured to generate a first set of information with the simulation model and compare the first set of information to a second set of corresponding information from the simulation model. In the above-described testing, the first set of information postdates the software revision and the second set of information predates the software revision.
