Sherlock-Automated-Design-Analysis-Software-5.2As leaders in quality, reliability and durability (QRD) solutions for the electronics industry, we at DfR Solutions are always innovating—as exemplified by the just-released Sherlock Automated Design Analysis™ software Version 5.2 that takes electronics design reliability analysis to the next level.

New Semiconductor Wearout Analysis Module

I’m excited about the latest iteration of the already robust Sherlock Automated Design Analysis™ software tool, particularly the all-new Semiconductor Wearout Analysis module. This is Sherlock’s first, but not last, foray into component-specific reliability prediction. It uses a combination of publicly available data and extensively researched physics of failure (PoF) degradation models to predict the minimum reliability demonstrated by the component vendor. By using PoF, this capability frees users from the limitations and inaccuracies inherent in assuming a constant failure rate and a simple Arrhenius relationship.

The response from the electronics industry has already been overwhelming. The avionics industry is excited to finally have a tool that can evaluate the long-life performance of commercial off-the-shelf (COTS) parts and allows them to be in compliance with increasing industry requirements to assess life-limited microcircuits (SAE ARP 6338). The automotive industry sees opportunity to implement realistic safety systems, as required by ISO 26262, based on a more accurate prediction of semiconductor failure rates. And all our customers, across industries, are hoping this is the beginning of the end of reliability prediction based on empirical handbooks, including MIL-HDBK-217, SR-332, and FIDES.

Other Advanced Features

In addition to groundbreaking semiconductor wearout analysis, Sherlock Version 5.2 provides users with:

  • IPC-2581 Full Function Mode Files Import and Support that enables them to create a new project within Sherlock or to define a new circuit card within an existing project. This import process is like other supported import formats like ODB++; IPC-2581 is an open global standard for assembly and manufacturing data supported by the IPC-2581 Consortium.
  • Part Modeling with the capability to selectively enable and disable FEA modeling for a specific part.
  • Modified Lead Modeling method that utilizes multiple elements, as needed, to model lead feet and shoulders. This modified method produces better FEA results for leads with long feet and/or shoulders.
  • Updated Part Wizard Patterns and Parts List Import Process to further streamline new product development.
