  • Publication number: 20120041746
    Abstract: An analysis tool analyzes a model to determine the digital effect of the model in a modeling or programming environment. With the analysis tool, a user can determine minimum hardware functionality needed to execute the software generated from the model. The hardware functionality may include the word size of the microprocessor that executes the software appropriately. The hardware functionality may also include the execution speed of the microprocessor executing the software. The hardware functionality may further include the functionality of other hardware elements, such as the word length of an Analog to Digital converter. The analysis tool enables a user to produce a system at a low cost while achieving necessary performance criteria.

  • Publication number: 20120035748
    Abstract: Exemplary embodiments allow users to interactively formulate and solve multivariable feedback control problems. For example, users can solve problems where a plurality of control elements are distributed over one or more feedback loops and need to be jointly tuned to optimize overall performance and robustness of a control system. Embodiments allow users to specify design requirements and objectives in formats familiar to the user. Embodiments can operate on tunable parameters to solve the control problem in a manner that satisfies the design requirements and/or objectives provided by the user.

    Abstract: Methods, systems and computer program products are provided for ignoring one or more output arguments of a function in a programming environment. Users or programmers may designate one or more output arguments that are not desired by the users. The called function determines which output arguments are designated by the users. The one or more output arguments designated by the users are ignored by the function. The called function may reclaim memory space for the output arguments designated by the users. The called function may also avoid operations for generating values for the output arguments designated by the users. The called function does not need to return values for the output arguments designated by the users.

  • Patent number: 8108717
    Abstract: A system receives a program, allocates the program to a first software unit of execution (UE) and a second software UE, executes a first portion of the program with the first and second software UEs in parallel, and determines whether an error is detected during execution of the first portion of the program by the first and second software UEs. The system also sends a signal, between the first and second software UEs, to execute a second portion of the program when the error is detected in the first portion of the program, executes the second portion of the program with the first and second software UEs when the error is detected, and provides for display information associated with execution of the first portion and the second portion of the program by the first and second software UEs.

  • Patent number: 8090565
    Abstract: In one embodiment, a system model models characteristics of a real-world system. The system model includes a plurality of sub-portions that each correspond to a component of the real-world system. A plurality of test vectors are applied to the system model and coverage achieved by the test vectors on the sub-portions of the system model is measured. In response to a failure of the real world system, a suspected failed component of the real-world system is matched to a particular sub-portion of the system model. A test vector to be applied to the real-world system to test the suspected failed component is selected in response to coverage achieved on the particular sub-portion of the system model.

  • Publication number: 20110296436
    Abstract: A system and method may generate executable block diagrams in which at least some of the blocks run in accordance with message-based execution semantics. A message may include an input data payload that does not change over time, and the message may persist for only a determined time interval during execution of block diagram. A message-based execution engine may control execution of message-based blocks in which a source block may generate a message at a particular point in time, the message may be sent to one or more destination blocks triggering execution of those blocks, and the message may be destroyed on or after a determined time interval. Other execution domains, such as a time-based or state-based execution domain, may be provided, and the system may implement a hybrid execution model. A verification engine may provide one or more tools for evaluating and verifying operation of message-based blocks.

  • Patent number: 8069178
    Abstract: In an embodiment, a computer-implemented technique for accessing heterogeneous objects in an array is discussed. The method determines a greatest common base class hierarchically common to elements populating a heterogeneous array. A common subset of methods that is available for use with the elements is identified. The common subset of methods belongs to the greatest common base class. A method supported by the common subset of methods is called with the array as a parameter. The method operates on the array as an array consisting of greatest common base class objects.

  • Patent number: 8065117
    Abstract: Programming or modeling environments in which programs or models are simulated or executed with tunable sample times are disclosed. The tunable sample times can be changed during the simulation or execution of the programs or models without recompiling the programs or models. The sample times are parameterized and the value of the sample times is changed during the simulation or execution of the programs or models. The sample times may be changed manually by a user. Alternatively, the sample times may be automatically changed by programmatically defining when and how the sample times are determined.
