Yield View of the Scaled-Sigma Sampling Method

After the Monte Carlo run for the Scaled-Sigma Sampling method completes, the Yield view of the Results tab shows the yield estimation.

The following table describes the information displayed in different columns of the Results tab.    

Column Description

Test

Name of the test.

Name

Name of the specification.

Yield in Sigma

The yield value in sigma. This value is calculated using the following formula:

where, erfinv is the inverse error function.

If the yield in sigma is greater than 8.2, the yield in percentage is displayed as 100%.

Yield in Percentage

Displays the yield value in percentage. This value is calculated using the following formula:

The yield in percentage value is displayed with 10 digits by default. To change the number of digits to be displayed for this value, set the value of the digitsToShowForYieldInPercentage environment variable. You can display a maximum of 53 digits for these values.

MC Yield

The yield value from the Monte Carlo run.

Target

The target to be achieved for the given specification.

Status

The convergence status for each specification.
