Difficult to figure out how built-in failure criteria correlates to test failures. Automatic PCB thermal conductivity calculation would be nice, similar to modulus calculation. Review collected by and hosted on G2.com.
Sherlock has the most updated reliability physics concept built-in, providing accurate results at the early phase of the design. It can even help the engineer to do reliability growth before the first design prototype release. Moreover, the tool developers have a strong background in reliability physics research and study. The thing I like most is that DfR Solutions invests more resources in improving Sherlock and tries to make it easy to use. Review collected by and hosted on G2.com.
In the earlier version, the software had many bugs. The later version after 5.0 seems to be more reliable, but still has minor bugs observed from one version to another. Besides, the user needs to have well-planning in doing data entry to Sherlock; any inaccurate data entry will cause the simulated results to be confusing. Review collected by and hosted on G2.com.
ODB import feature makes it very easy to create initial model with most of the necessary information. Parts library makes it easy to apply previously collected data. Thermal Cycling analysis runs super fast. The strain based component of damage predicted in the Random Vibration analysis solver is a huge value-add. We currently have no other means to assess such damage and have been able to predict failure modes that would (or had) otherwise been missed. Review collected by and hosted on G2.com.
Adding detail can be difficult. Hard to model mechanical parts/interface with external FEA. Parts List management is partially automated but doesn't always work if there are user input values overwriting library values. Board outline editor is painful. Natural Frequency analysis runs every time Random Vibration runs (i.e. can't just use saved results if applicable) adding unnecessary computation time. Review collected by and hosted on G2.com.
The mechanical simulations like Natural Frequency and Strain Gauge analysis are being tested using physical samples, getting a good correlation. Review collected by and hosted on G2.com.
The CAF need post-analysis to determine the real risks. The are some mechanical restrictions for modeling sub-assemblies. Review collected by and hosted on G2.com.
