Set Hypertrophic Limit
Tools Supported: FlexTest
Scope: All modes
Usage
SET HYpertrophic Limit Off Default To percentage
Description
Specifies the percentage of the original design’s sequential primitives that can differ from the good machine before the tool classifies them as hypertrophic faults.
The Set Hypertrophic Limit command specifies the maximum percentage of original design to good machine difference that the tool allows before classifying the fault as hypertrophic and dropping it from the active fault list.
The term hypertrophic fault refers to a fault whose effects spread extensively throughout the design, meaning that the tool finds many internal value differences between the faulty machine and the referenced good machine. In fault simulation, hypertrophic faults require large amounts of memory and cpu time to process and can significantly affect the performance of fault simulation. To improve fault simulation performance, FlexTest can drop these faults with little consequence to the accuracy of fault coverage.
Arguments
∙Off
A literal that specifies for FlexTest to not define any hypertrophic faults.
∙Default
A literal that resets the hypertrophic limit to the default value of 30 percent.
∙To percentage
A literal and positive integer pair that specifies the maximum percentage of differing sequential primitive output values that FlexTest allows before defining a fault as hypertrophic. The integer must be a value from 1 to 100.
