Model Objects That Receive Coverage
16-19
The total number of coverage points for a two-dimensional lookup table is the number of
row break points in the table plus one, multiplied by the number of column break points
in the table 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.
If you select the Saturate on integer overflow coverage metric, the 2-D Lookup Table
block receives saturate on integer overflow coverage. For more information, see “Saturate
on Integer Overflow Coverage”. The software treats each element of a vector or matrix as
a separate coverage measurement.
n-D Lookup Table
The n-D Lookup Table block receives lookup table coverage. For an n-dimensional lookup
table, the number of output break points equals 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 output
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.
If you select the Saturate on integer overflow coverage metric, the n-D Lookup Table
block receives saturate on integer overflow coverage. For more information, see “Saturate
on Integer Overflow Coverage”. The software treats each element of a vector or matrix as
a separate coverage measurement.
