Field |
Type |
Description |
name |
string
|
Name of the statistical parameter.
|
mean |
number
|
Mean value of the statistical parameter.
|
corners |
matrix
|
Corner values for the statistical parameter provided as a Cx1 matrix where C is the number of process corners defined in the library master file.
Note: The values for the process corners should follow the same order as in the library master file.
|
LOCAL |
struct
|
A struct describing the LOCAL level variation of the X-th statistical parameter with the following fields:
- distribution: a string that defines the type of the PDF used to describe the LOCAL level variation. Currently, the options are 'normal' (Gaussian) or 'pearson4' (Non-Gaussian).
- sigma: a number that defines the standard deviation of the LOCAL level variation.
- gamma1: a number that defines the skewness of the LOCAL level variation (for pearson4 distribution only)
- beta2: a number that defines the kurtosis of the LOCAL level variation (for pearson4 distribution only)
- CORRGROUP: Name of the spatial correlation group that this statistical parameter belongs to. The correlation group must be defined in the library master file.
Note: It is optional to provide a CORRGROUP for statistical parameters.
|
GLOBAL |
struct
|
A struct containing the GLOBAL level variation of the X-th statistical parameter with the following fields:
- distribution: a string that defines the type of the PDF used to describe the GLOBAL level variation. Currently, the options are 'normal' (Gaussian) or 'pearson4' (Non-Gaussian).
- sigma: a number that defines the standard deviation of the GLOBAL level variation.
- gamma1: a number that defines the skewness of the GLOBAL level variation (for pearson4 distribution only)
- beta2: a number that defines the kurtosis of the GLOBAL level variation (for pearson4 distribution only)
- GLOBALGROUP: Name of the GLOBALGROUP defined in the top level library master file (XML file). (If a GLOBALGROUP is provided, then the description in the library master file (XML file) has higher priority than the data file)
Note: It is optional to provide a GLOBAL level variation for statistical parameters.
