摘要： A method, system, and integrated circuit including selectively added timing margin. The method, for integrating statistical timing and automatic test pattern generation (ATPG) to selectively add timing margin in an integrated circuit, includes identifying, while a chip is in design, paths that are unable to be robustly tested “at speed” during manufacturing test, running statistical timing to calculate a margin to be applied to the paths, updating design specifications for margin to be applied to the paths, and optimizing chip logic based on updated design specifications.

摘要： A method and structure for designing an integrated circuit chip is disclosed. The method supplies a chip design, partitions elements of the chip design according to similarities in voltage requirements and timing of power states of the elements to create voltage islands, creates a floorplan of the voltage islands, assesses the floorplan, repeats the partitioning and the creating of the floorplan depending upon a result of the assessing process, and outputs a voltage island specification list.

摘要： A structure, system, and method block clock inputs to clock domains (using a computer). While the clock domain inputs are blocked, the structure, system, and method perform a first timing test only of signals that are transmitted within the clock domains (using the computer) by only observing latches that receive signals from sources within the clock domains. The structure, system, and method also unblock the clock inputs to the clock domains (using the computer). While the clock domain inputs are unblocked, the structure, system, and method perform a second timing test only of signals that are transmitted between the clock domains by only observing latches that receive signals from other clock domains.

摘要： A design structure is embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit. The design structure includes an input register coupled to a data processing unit input and a test operation mode and functional operation mode. In the test mode operation, the register operates in a clocked mode such that, during the test operation mode, the register propagates data to the data processing unit in response to a clock signal. In the functional operation mode, the register operates in a data flush mode such that the register propagates data to the data processing unit in response to the data. The functional mode is enabled by a flush enable signal and the test mode is enabled by an opposite state of the flush enable signal.
