Model Objects That Receive Coverage
16-11
Direct Lookup Table (n-D)
The Direct Lookup Table (n-D) block receives lookup table coverage. For an n-
dimensional lookup table, the number of output break points is the product of all the
number of break points for each table dimension.
Lookup table coverage measures:
• The number of times during simulation that each combination of dimension input
values is between each of the break points.
• The number of times during simulation that each combination of dimension input
values is below the lowest break point and above the highest break point for each
table dimension.
The total number of coverage points for an n-dimensional lookup table is the product of
the number of break points in each table dimension plus one. In the coverage report, an
increasing white-to-green color scale, with six evenly spaced data ranges starting with
zero, indicates the number of time steps that the software measures each interpolation or
extrapolation point.
The software determines a percentage of total coverage by measuring the total
interpolation and extrapolation points that achieve a measurement of at least one time
step during simulation between a break point or beyond the end points.
Discrete Filter
If you select the Saturate on integer overflow coverage metric, the Discrete Filter
block receives saturate on integer overflow coverage. For more information, see “Saturate
on Integer Overflow Coverage”.
Discrete FIR Filter
If you select the Saturate on integer overflow coverage metric, the Discrete FIR Filter
block receives saturate on integer overflow coverage. For more information, see “Saturate
on Integer Overflow Coverage”.
Discrete-Time Integrator
The Discrete-Time Integrator block receives decision coverage. The Simulink Verification
and Validation software reports decision coverage for these parameters:
