N

Default: 1e-07

The value of N depends on the floating-point tolerance check setting that you specify. Use this setting to specify a custom tolerance value for checking the numerical accuracy in the generated test bench. When you set the Floating point tolerance check based on to:

• relative error, the default is a tolerance value of 1e-07. When you use this floating-point tolerance check setting, specify the tolerance value as a double data type.

• ulp error, the default is a Tolerance Value of 0. When you use this floating-point tolerance check setting, specify the tolerance value as an integer. You can specify a Tolerance Value, N, that is greater than or equal to 0.

Set or View This Property

To set this property, use hdlset_param or makehdl. To view the property value, use hdlget_param.

Example

To specify the floating-point tolerance value for a model, use the hdlset_param function to specify the tolerance strategy, and then enter the tolerance value. For example, to check the floating-point tolerance based on ULP error and enter the tolerance value:

hdlset_param('sfir_single', 'FPToleranceStrategy', 'ULP');       % check for floating-point tolerance based on the ULP error
hdlset_param('FP_test_16a', 'FPToleranceValue', 1);              % When using ULP error, optionally enter tolerance value greater than or equal to 0
