Abstract: A design structure for a pipeline electronic processor device may be embodied in a machine readable medium for designing, manufacturing or testing a processor integrated circuit. The design structure may embody a pipeline electronic circuit that enables power conservation in the stages of the pipeline via a simulation that identifies clock-gating opportunities among the stages of the pipeline. In one embodiment, simulation results assist a designer in the design of the pipeline electronic circuit design structure to achieve power conservation by incorporating clock-gating circuitry among the stages of the pipeline at clock gating opportunity locations that the simulation identifies.

Abstract: Dangling pointers and memory leak locations within software are detected. As the software allocates and deallocates memory, lists of pointers referencing the memory, and pointer status, are maintained. As the software writes new addresses within pointers and reads addresses referenced by the pointers, the pointer lists are maintained to determine whether the pointers are dangling and to detect memory leak locations. A balanced binary tree having a number of nodes can be maintained. The nodes represent heap or stack records. Each heap record corresponds to heap memory that has been allocated and has a list of pointers referencing the heap memory. Each stack record corresponds to a stack within which a stack frame is allocated each time a function is entered. The stack record has frame records corresponding to the stack frames. Each frame record has a list of pointers referencing the corresponding stack frame.

Abstract: Mechanisms are provided for refining an abstraction of a netlist for verification or synthesis of an integrated circuit design. The mechanisms receive an abstracted netlist corresponding to an original netlist of the integrated circuit design. The mechanisms determine elements already present in the abstracted netlist and refine the abstracted netlist by expanding the abstracted netlist to include additional elements that are correlated with the elements already present in the abstracted netlist to thereby generate a refined abstracted netlist. In addition, the mechanisms utilize the refined abstracted netlist to perform at least one of verification or synthesis of the integrated circuit design.

Abstract: Techniques are disclosed for conveying which hardware components of a logically partitioned computer system are assigned to a selected logical partition of the computer system. Partition information for the computer system is received. Further, a request is received from a user to view which hardware components of the computer system are assigned to a selected logical partition of the computer system. Based on the received partition information, one or more hardware components are determined that are assigned to the selected logical partition. Based on the determined hardware components, a virtual model of the computer system is generated that visually distinguishes hardware components assigned to the selected logical partition from hardware components not assigned to the selected logical partition. The virtual model is output responsive to the request.
