Patent ID: 8225258

Claim:
A method comprising: generating, by using a computer, a sample-data distribution function F D (d) based upon a set of die bump distance measurements associated with a first set of die bumps, where d is a real-valued variable and F D (d) is the fraction of the number of die bump distance measurements in the set of die bump distance measurements less than or equal to d; generating a sample-data distribution function F Z (z) based upon a set of lumped circuit parameter measurements associated with a second set of die bumps, where z is a real-valued variable and F Z (z) is the fraction of the number of lumped circuit parameter measurements in the set of lumped circuit parameter measurements less than or equal to z; and generating a set of pairs {(d k , z k ), k=0, 1, . . . , K}, where F D (d k )=F Z (z k ); and wherein the die bump distance is a distance from a die bump center to die center.
