Simulation Assisted Reliability Assessment (SARATM) Software

The CALCE Simulation Assisted Reliability Assessment (SARA) software includes a variety of tools for assisting in life assessment and reliability estimation of electronic parts and assemblies.  The CALCE SARA software uses physics-of-failure based principles to assess whether a part/system can meet defined life cycle requirements based on its material, geometry, and operating characteristics.  The software provides design capture facilities to import design data as well as interfaces to define operational and environmental loading conditions.  The software allows designs to be assessed prior to fabrication.  The software supports the CALCE Design for Reliability (DfRTM) assessment process, which allows design engineers to interactively make design changes and rapidly assess their impact on product reliability. Using the software, the life expectancy of electronic hardware under both anticipated life cycle loading conditions and elevated stress tests can be determined. This information can be used to determine acceleration factors associated with elevated stress tests. The assessment of life expectancy under anticipated life cycle loading conditions is referred to as the virtual qualification (VQTM) process.
