29 Simulink Performance Tools 1.1 Release Notes

29-2

New Features

This section introduces the new features and enhancements added in Simulink

Performance Tools 1.1 since Simulink Performance Tools 1.0 (Release 12.0).

The following tools were enhanced:

•“Model Coverage Tool” on page 29-2

•“Graphical Merge Tool” on page 29-4

For an introduction to the Simulink Performance Tools, see the Release Notes

for Release 12.

Model Coverage Tool

This section describes features and enhancements added to the Model

Coverage Tool

Additional Coverage Types

This version adds the following types of coverage analysis:

•Condition coverage

Examines blocks that output the logical combination of their inputs, e.g., the

Logic block, and Stateflow transitions. A test case achieves full coverage if it

causes each input to each instance of a logic block in the model and each

condition on a transition to be true at least once during the simulation and

false at least once during the simulation.

•Modified condition/decision coverage (MC/DC)

Examines blocks that output the logical combination of their inputs, e.g., the

Logic block, and Stateflow transitions to determine the extent to which the

test case tests the independence of logical inputs and transition conditions.

•Look-up table (LUT) coverage

Examines blocks, such as the Look-Up Table block, that output the result of

looking up one or more inputs in a table of inputs and outputs, interpolating

between or extrapolating from table entries as necessary. Lookup table

coverage records the frequency that table lookups use at each interpolation

interval.

See “Coverage Analysis” in the “Model Coverage Tool” section of Using

Simulink for more information.
