20100153053 | Stream Based Stimulus Definition and Delivery via Interworking - An approach is provided to manage test transactors that interface with components of a hardware design. A first set of transactors is launched with the first set sending stimuli to various components that correspond to the first set of transactors. A manager receives signals when transactors of the first set have completed at which point a second set of transactors is identified that are dependent upon the first set transactors that completed. The second set of transactors is launched by the manager. The manager further facilitates transmission of data used by the various transactors. Transactors generate and provide stimuli to various components included in a hardware design, such as a System-on-a-Chip (SoC). Results from the hardware design are passed to the transactors which, in turn, pass the results back to the manager. In this manner, results from one transactor may be made available as input to another transactor. | 06-17-2010 |
20110107146 | Trace Reconstruction for Silicon Validation of Asynchronous Systems-on-Chip - A test system collects passing event data and failing event data, and merges the collected data into passing subsequences and failing subsequences, respectively. The test system identifies an overlap area between the passing subsequence and the failing subsequence in regards to time slices and tracepoint slices, and creates passing transactions and failing transactions using the event data corresponding to the overlap area. Next, the test system detects a timing discrepancy between the first passing transaction relative to the second passing transaction compared with the first failing transaction relative to the second failing transaction. The test system then reports the detected timing discrepancy, which allows a test engineer to perturb the test program in order to more frequently catch intermittent failures caused by asynchronous timing conditions. | 05-05-2011 |
20130297280 | Verification of Design Derived From Power Intent - An approach is provided in which a power design verification system retrieves a power intent data corresponding to a power design, which identifies the power design's power modes and power mode transition conditions. The power design verification system selects one of the power mode transition conditions, which identifies input signals that invoke a transition from a first power mode to a second power mode. In turn, the power design verification system generates simulation stimuli based upon the identified input signals and simulates the power design utilizing the generated simulation stimuli accordingly. | 11-07-2013 |
20130346375 | Equivalence Classes Over Parameter State Space - An approach is provided in which an equivalence class generator selects a configurable module that includes control points and configuration parameters. The configuration parameters define a parameter state space of the configurable module. The equivalence class generator utilizes the control points to generate equivalence classes, which include class representatives that indicate values for the configuration parameters. Next, one of the class representatives are selected and verified from each of the equivalence classes. In turn, the verification of the class representatives verifies the parameter state space of the configurable module. | 12-26-2013 |

20090042573 | Radio Bearer Dependent Forwarding For Handover - This invention employs an inherent tradeoff in a radio bearer dependent data handling method for intra-E-UTRA handoffs. For user equipment using real time data, the source node forwards to the target node not yet acknowledged real time service data units and disconnects. This makes the handoff latency short at the expense of data traffic between nodes. For user equipment not needing real time data, the source node continues to receive user equipment acknowledgements during a time out period and only forwards service data units acknowledged during the time out period. This reduces X2 interface traffic between the source and target nodes but extends the handoff latency. | 02-12-2009 |

20100080137 | Primary and Secondary Associations for Improving Cell Edge Performance in Cellular Networks - Embodiments of the invention provide a method to efficiently enable Network MIMO for use in the downlink direction. An association is established between a primary NodeB in a first cell and a secondary NodeB in an adjacent second cell. A set of downlink transmission resources is reserved for use by both the primary NodeB and the secondary NodeB. A transport block is transmitted from the secondary NodeB simultaneously with the primary NodeB to a user equipment (UE) near the edge of the first cell in response to a schedule provided by the primary NodeB. A time instance of the reserved transmission resources is released by the secondary NodeB when no simultaneous transmission of a transport block is scheduled within a minimum time. | 04-01-2010 |

20120314739 | Radio Duty Cycle Minimization Techniques for Transmission-Initiated Wireless Multi-Hop Networks - The duration of receiver on-times may be minimized by sensing and reacting to communication channel power levels at intervals. When no energy is detected on the communication channel, then the receiver may be turned off for a channel sampling interval. If energy is detected on the channel, then the receiver may remain on to determine if a received message is associated with the device. Receiver on-time may also be minimized by adjusting the timing of messages used for broadcast messages sent by routing or other protocols. Broadcast messages, such as network routing topology messages, may be controlled in two phases. In a first phase, the broadcast messages are sent with at a high rate to allow nodes to join the network rapidly. In a second phase, the broadcast messages are sent with at a lower rate to minimize interference with data and other messages in the network. | 12-13-2012 |
20130198542 | SYSTEMS AND METHODS OF TASK ALLOCATION IN A MULTIPROCESSING ENVIRONMENT HAVING POWER MANAGEMENT - Systems and Methods for task allocation in a multiprocessor environment employing power management techniques are described wherein tasks are allocated relative to the density given by the ratio of worst-case-execution time and deadline of a task and also the harmonicity of a task's period with respect to a task-set. Tasks are allocated to a given processor based on either minimum density or maximum harmonicity depending on which allocation results in a lower clock frequency. Assigning a task to the processor with lowest density results in balancing the density across processors while assigning task to the processor with maximum harmonicity attempts to maximize the utilization of the processor. | 08-01-2013 |
