Abstract: Estimation related to void formation and breakage/failure is performed through numerical simulation using dominant parameters of EM damage in a metal interconnect. The metal interconnect is divided into elements. Current density and temperature distribution is obtained using numerical analysis. Atomic flux divergence AFDgen of each element and the distribution thereof is calculated by using material property constants determined through acceleration testing. The reduction of volume per one calculation step in the simulation is found by multiplying the volume of each element, the length of time corresponding to one calculation step, and the atomic volume corresponding to the calculated AFDgen. Based on the reduced amount of volume, the thickness of each element decreases. The elements having a decrease in thickness show the fact that voids have formed.

Abstract: A method for evaluating the upper bound fault coverage of an integrated circuit (IC) or a portion thereof from register transfer level (RTL) description is provided. The method requires the analysis of a circuit described in RTL consisting of primary input and output pins as well as devices connected to each other and/or to the primary pins to determine the controllability and observability of each pin of the circuit to ‘stuck at zero’ and ‘stuck at one’ conditions. The upper bound fault coverage is then determined based on the ratio between the number of pins that are both controllable and observable and twice the number of pins in the circuit. The method does not require a dynamic simulation for its fault coverage assessment and hence is advantageous over other methods consuming significant time and resources.

Abstract: A method and apparatus are provided for determining quality metrics associated with a test pattern used to test an integrated circuit (IC). The delays associated with (1) a longest sensitizable path through the IC that includes the delay fault and (2) an actual path exercised by the test pattern through the IC that includes the delay fault are determined. A difference between the delays is then obtained. The difference is then combined with a difference between a speed at which the test is performed and a design specification operating speed of the IC for the actual path. The sum represents the first quality metric associated with the test pattern for a given fault site. The ratio of the delays of the actual path to the longest sensitizable path represents the second quality metric associated with the test pattern for a given fault site.

In order to identify the integrated circuit with a value for its operating property, there are provided at least two registers whose outputs are logically combined bit by bit via OR gates.

The storage of this value on the integrated circuit itself simplifies the later identification on the housing of the integrated circuit.
