Reliability Modeling Software Reduces Testing Time, Improves Results for Innovative Auto Electronics

Reliability_Modeling_Software.jpgDesigned to perform reliably and safely, automotive electronics are subjected to rigorous tests based on strict industry standards like ISO 26262 These critical components are often the determining factors between innovation success and catastrophic failure resulting in warranty/liability claims, lawsuits and high manufacturing costs.

The importance of the testing cannot be understated. However, even the most streamlined testing procedures can take months or sometimes years to complete, particularly when consumer safety is at risk. Even after a protracted amount of time, there’s no guarantee that a prototype will meet reliability and specification requirements – and that could mean more rounds of expensive and time-consuming physical tests on GPUs, auto IoT communications and intelligent functionality systems.

Reliability modeling software provides time and testing efficiencies that reduce the number of required physical testing iterations and improve the chances that prototypes will pass qualification tests in the first round.

Time efficiencies

Reliability modeling software speeds testing times by letting engineers:

  • Build and test virtual products: Using data files created by design engineering, products can be virtually built and subjected to anticipated user environments to predict reliability and reveal potential weaknesses
  • Modify designs in near real-time: Design changes can be made to the virtual product data files almost immediately, eliminating wait time for prototype re-fabrication
  • Quickly run mechanical simulation: Tests that disclose ways to build a more time- and cost-efficient design can be run in minutes, not days
  • Significantly cut costs: Reliability and quality improvements can be made early on in the design process, keeping prototyping costs from spiraling and aggressive design schedules intact 

Testing efficiencies

A physics-based automated design analysis tool – like the one-of-a-kind Sherlock Automated Design Analysis™ Software – helps engineers design reliability right into automotive electronics. The software helps improve the chances that prototypes will pass qualification tests on the first try by allowing engineers to:

  • Identify testing opportunities: Areas where specific, beneficial testing could take place will be uncovered
  • Evaluate design choices: Having real world insights into how design choices impact product performance reliability keep both premature failure rates and long-term cost of ownership low
  • Gain project-specific insights: The software’s versatility addresses a variety of user needs, from determining thermal cycle test requirements needed to replicate the use environment to identifying expected failure rates and times for a given set of conditions
  • Align reliability goals with metrics and requirements: Identifying and documenting desired lifetime and product performance upfront helps in all aspects of product development, including defining end-use survivability expectations without assuming specific failure rate behavior

Reliability testing is a necessary step in ensuring the success of automotive components. Now, with reliability modeling software, it can be done without compromising timelines and budgets, or risking repeated qualification test failure.
