Global Part Database
FEA 3D Model
Sub-Assembly Analysis
FEA 3D Viewer
Result Management
Failure Rate - Telcordia SR-332
Global Part Database
Created to allow
Sherlock users to store
and share part data
across their own projects
and with other Sherlock
users.
 Interaction with other
commercial or customer
databases is also
available and is
undergoing testing

Global Part Database
Operates 24x7 and is
accessible via the Internet
 Provides users with
private “cloud” storage for
their own confirmed part
data
 Allows users to view
ranked alternative part
data while maintaining
complete privacy for all
users.
 Community sharing
reduces data entry and
increases data accuracy

FEA 3D Modeling

ICT and Shock / Vibration Analysis




fully 3D elements for the PCB,
components and mount pts
increase simulation accuracy
more reliable meshing
algorithm
increased analysis flexibility
• sub-assemblies, heatsinks, chassis analysis

Multi-core and 64 bit support

Faster analysis
Sub-Assembly Analysis
Attach one or more CCA subassemblies to a primary CCA



mezzanine cards supported by
standoffs
edge-connected cards
Sherlock automatically analyzes the
main CCA and all CCA sub-assemblies
during a single ICT or Shock/Vibration
analysis task

Layer results and component results
automatically generated for all circuit
cards

FEA 3D Viewer
Allows users to visualize 3D models and results
 Interactively view 3D model with colors based on displacement or strain values.
 Optionally amplify the displacement results to visualize small changes
 Publication-ready image files can be created at any time
Viewer can be launched from inside of Sherlock or directly from the desktop.

Result Management
CCA inputs and analysis results
can be saved for later review
and/or comparison.
 Arbitrarily named result files can
be stored anywhere in the file
system


allows users to organize
results in any convenient
manner
Can be launched from within
Sherlock or directly from the
desktop.

Multiple viewers can be active at
the same time, allowing side-byside review of past and present
analysis results.

Result Management
Archived results contain all input information (BOM, layers, stackup) so you can
track what has changed between simulations

How
Failure Rate - Telcordia SR-332

Enhanced to allow users to choose between the following models:

MIL-217 and SR-332
Sherlock automatically computes a failure rate for each CCA component based on
the part data currently defined in the Parts List

Uniform set of Failure Classes has been defined by DfR Solutions to be assigned to
each CCA part.

Failure class designators and failure rate related part properties can be stored in the
Sherlock local and global part databases by part number



significantly reduces data entry and maintenance across a collection of CCAs
and projects over a period of time.
