Architecture design analysis and verification (FMEA)

ARCHx™ is a tool used to perform architecture design verification and essential design documentation. Using a version of the Design Failure Modes and Effects Analysis (DFMEA) method called Design Deviation and Mitigation Analysis (DDMA), the tool is used to identify issues (called Deviations) in a design that must be mitigated. ARCHx has replaced traditional methods with intelligent, next generation features to reduce engineering hours.  exida expert knowledge within ARCHx has with content sensitive suggestions for known deviations and mitigation measures for different types of architectural building blocks. This feature can reduce engineering time and improve the quality of the architecture design verification. exida calls this method Design expert Deviation and Mitigation Analysis (DexDMA).  

ARCHx gathers and organizes design documentation needed for devices where Functional Safety or Cybersecurity certification is a requirement. The information gathered for FMEDA is directly available to the FMEDAx™ application to speed-up the FMEDA process. By way of the Test Manager feature, ARCHx allows the analyst / team to create integration and/or software module test objectives for each subsystem / unit while the goals and design intent for proper interaction between units are fresh in their mind. Integration Test objectives can be linked to one or more Units for quick reference and sorting.

Device failure rate and failure mode prediction for safety and availability analysis

The exida FMEDAx™ Tool is used to perform and document a detailed component level FMEDA on a System or Subsystem consisting of electrical, mechanical, or sensor components.  The FMEDAx tool accepts the functional failure mode data from ARCHx and allows faster and more accurate subsystem/device failure prediction. Designers save time and discover design issues early in the design process.

Component Reliability Database (CRD) takes FMEDA predictions to a New Level of Accuracy

The exida CRD helps you generate the most accurate safety & reliability predictions possible, leading to better design decisions. The comprehensive data set undergoes rigorous calibration against field failure data and is updated regularly. Information on useful life, failure modes / distributions, impact of soft error rates, packaging, operating environment, etc. is included in the standard data set; this eliminates the need for you to search for / fill in missing data.  The Environmental Profile Editor is also available to allow the failure data / useful life to be customized for specific situations.

exida provides the REQxTM tool to capture and manage requirements with expert knowledge support. Each requirement has an attribute and status. Requirements can be entered hierarchically to show more detail as the design progresses. Full tracing can be done to show related validation test objectives and design implementation units.  With a direct connection to ARCHx and FMEDAx, new requirements derived from design analysis can be quickly created without leaving the context of OEMx – reducing time spent and lost requirements.
