Enter the tolerance value based on the floating-point tolerance check setting that you specify

Model Configuration Pane: Test Bench

Description

Enter the tolerance value based on the floating-point tolerance check setting that you specify.

Settings

1e-07 (default) | 0

The value must be a positive integer or a double data type.

The default tolerance value depends on the floating-point tolerance check setting that you specify. 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. You can specify a Tolerance Value, N, that is less than or equal to 1e-07.
• 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.

Tips

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

For 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:

% Check for floating-point tolerance based on ULP hdlset_param('sfir_single', 'FPToleranceStrategy', 'ULP');

% When using ULP, optionally enter tolerance value >= 0
hdlset_param('FP_test_16a', 'FPToleranceValue', 1);

% Generate HDL testbench with specified tolerance setting makehdltb('sfir_single/symmetric_fir')
