Relational boundary coverage relative tolerance

Relational boundary coverage relative tolerance

Model Configuration Pane: Coverage


The Relational boundary coverage relative tolerance specifies the value of relative tolerance for relational boundary coverage. This parameter applies only to input signals with a floating-point data type, such as double. The relational boundary floating-point tolerance equation is max(absTol, relTol* max(|lhs|,|rhs|)). For more information, see Relational Boundary Coverage.

Relational boundary coverage checks blocks with relational operations, such as the Relational Operator block. The analysis checks that, for each operation, the floating-point operands differ by no more than the value of this parameter.

For example, if you enter 0.01, the analysis checks operations where lhs < = rhs executes with operands that differ by at most:

0.01 * max(|lhs|,|rhs|)


To enable this parameter, select the Enable coverage analysis and Relational boundary parameters.


1e-5 (default) | floating-point value in the range (0,1)

Enter a floating-point value between 0 and 1 for the relational boundary absolute tolerance.
