For the W76-1 Arming Fuzing Subsystem (AFS) project, the use of ASC codes such as Xyce has helped qualify designs in hostile environments by providing a drastically improved circuit model.

As a design tool, Xyce was instrumental in the successful design of the SA3989 because of its ability to conduct pad-to-pad simulations of the parts prior to manufacture.

Charon uses fininte element devices to analyze semi-conductor models with defect reactions. Similarly, Xyce has been used to look at circuit models with irradiation effects.

Integrated Stockpile Evaluation (ISE) is just one application of large-scale computing where a “massively-serial” circuit runs to support firing-set variability analysis. Our department’s services provide modeling & simulation support to Component Surveillance Program (CSP) by identifying key devices to focus research and testing. Furthermore, our technologies provide a predictive capability to Enhanced Surveillance Campaign (ESC) by identifying trends in device characteristics as a result of aging and the impact upon system performance margins.
