    摘要: Among other things, one or more systems and techniques for defining a group bounding box for related cells of an integrated circuit, and generating a new layout for the integrated circuit comprising the group bounding box are provided herein. That is, one or more group bounding boxes are defined based upon positional values of related cells. Such group bounding boxes are placed within the new layout based upon a placement technique, such as an objective function that takes into account wire length, timing, and cell density, for example. The one or more group bounding boxes are sized or reshaped to reduce cell overlap within the new layout. In this way, the new layout comprises related cells, bound by one or more group bounding boxes, that are placed within the new layout according to a configuration that mitigates wire length and timing delay of the integrated circuit.

    摘要: A system and method for detecting soft-failures in integrated circuits is provided. A circuit includes a combinatorial logic block having a first signal input and a second signal input, and a latch coupled to an output of the combinatorial logic block. The combinatorial logic block produces a pulse when only one of either a first signal provided by the first signal input or a second signal provided by the second signal input is a logical high value, and the latch captures the pulse if the pulse has a pulse width greater than a second threshold. The pulse has a pulse width that is based on a timing difference between a first signal transition on the first signal and a second signal transition on the second signal, the combinatorial logic block produces the pulse if the timing difference is greater than a first threshold, and the combinatorial logic block operates with balanced inputs.

    摘要: System and method for effectively detecting small delay defects is disclosed. The method first loads layout information of an integrated circuit. Then, the nets and paths of the integrated circuit are partitioned into two groups based upon their physical information. The physical information comprises the length of each path and net and the number of vias at each path and net. A timing-aware automatic test pattern generator is configured to generate test patterns for the first group having paths and nets susceptible to small delay defects. A traditional transition delay fault test pattern generator is configured to generate test patterns for the second group.
