Database mining, analysis and optimization techniques in conjunction with
the model-based functional coverage analysis are used to turn raw verification
and coverage data into design intelligence (DI) and verification intelligence (VI).
The required data and attributes are automatically extracted from verification,
simulation and coverage analysis databases. Design finite state machine extraction,
design functional event extraction, and automatic coverage model generation and
optimization techniques are applied to the design HDL description. Coverage model
tuning and optimization directives, as well as test spec tuning and optimization
directives are generated based on the analysis and mining of various verification,
simulation, and coverage databases. An integrated web-based interface portlet is
used for access, analysis and management of the resulting databases, generated
reports and verification directives. Dissemination rules are used to automatically
generate and distribute analysis reports and verification directives to engineers
at wired or wireless interface devices via Internet or Intranet.
