Abstract: Exemplary embodiments provide adapted components that may be used by a computer program under different execution contexts. The adapted components may include platform independent source code which may be executed regardless of the execution context in which the component is deployed. Adaptation logic may wrap the execution context independent component in a wrapper. The wrapper may perform data marshaling between the execution context independent component and a computer program invoking the execution context independent component, or the host system on which the computer program is deployed. The execution context independent component may be adapted to a new execution context dynamically the first time that the execution context independent component is invoked in the execution context. Thereafter, the execution context independent component may be invoked statically without the need to re-adapt the component.

Abstract: A system and method supports reusing model components or component artifacts in a first modeling environment where the model components or artifacts were created in a second environment.

A wrapper object is constructed to convert between differences identified among the two interfaces. Utilizing the wrapper object, the model components or component artifacts are reused in the second environment.

The device may provide, for display, the set of elements in the second display condition based on the other attribute for the element.

Users can tune controllers using characteristics familiar to typical users rather than having to specify gain values for the controller, which may be difficult for a user to relate to the performance of a controller.

The executable code segment may be associated with an emitter, and the program code, when executed, may be associated with a plurality of execution states. Each execution state, of the plurality of execution states, may correspond to a state of execution at a point in the execution of the program code that causes an event, of the plurality of events. The system may execute the executable code segment. The system may receive, from the emitter and based on executing the executable code segment, a program state corresponding to the particular execution state. The emitter may emit the information based on a particular event caused by executing the executable code segment. The system may collect the program state and information describing the particular event.

Abstract: Exemplary embodiments allow a user to create configurations for use in distributed computing environments. Configurations can be arranged in hierarchies in which elements of the hierarchy can inherit characteristics from elements in other layers of the hierarchy. Embodiments also allow a user to flatten a hierarchical configuration to remove hierarchical dependencies and/or inheriting capabilities of elements in the hierarchy. Exemplary embodiments further allow users to deploy a distributed computing configuration on their desktop to evaluate performance of the configuration and then deploy the configuration in a distributed computing environment without having to change programming code run on the desktop/distributed computing environment.

Abstract: Exemplary embodiments provide techniques for replacing a portion of a state diagram with a generalized, canonical version of the portion. The canonicalized version mimics the structure or semantics (or both) of the portion of the state diagram, although the canonicalized version need not be a perfect match for the structure or semantics of the portion. Exemplary embodiments further provide techniques for identifying a portion of a state diagram for reuse, and generating a canonicalized version of the portion.

The device applies clock rate pipelining to adjust the sample rate associated with the portion of the model so that the sample rate substantially equals the clock rate, and generates code associated with the model and the applied clock rate pipelining.

Abstract: Systems and methods automatically generate optimized hardware description language (HDL) code for an executable model. An intermediate representation is generated for the executable model, which includes model elements. The intermediate representation includes nodes corresponding to the model elements. The HDL code is generated from the intermediate representation. A synthesis tool chain performs hardware synthesis using the HDL code. The synthesis tool chain generates performance characteristics of hardware components defined by the synthesis tool chain. The performance characteristics are mapped to the nodes of the intermediate representation, and one or more performance bottlenecks are identified. At least one optimization technique is applied to the intermediate representation to produce a revised intermediate representation, which is then used to generate new HDL code. The process may be repeated until the performance bottlenecks are eliminated or a termination criterion is met.

Abstract: A modeling and simulation environment enables a user to create a model of a stiff chemical or biological system. The stiff chemical or biological system refers to a system that includes at least two or more different time scales of the chemical or biochemical reactions. The modeling and simulation environment also enables the user to solve the stiff chemical or biological system using a leaping algorithm. The leaping algorithm may leap over simulation of the reactions occurring in the time interval to accelerate the simulation of the chemical or biological system. The algorithm maximizes the size of the time interval by adjusting the size of the time interval using a bracketing algorithm.

Abstract: A system and method tests for functional equivalence prior to automatically retiming a high-level specification. An Intermediate Representation (IR) includes one or more graphs or trees based on the high-level specification. A functional equivalence (FE) analyzer determines whether one or more components in the graph meet certain value and state conditions and thus is a candidate for retiming. A scheduler can use components that fail FE as a retiming boundary.

Abstract: A mechanism for converting a graphical model of a system into an intermediate representation (IR) of a model is discussed. The mechanism alters the IR, and uses the altered IR to create a new or updated graphical model of the system that may be viewed and simulated by a user. Once the user is satisfied with the alterations to the IR, the IR or the graphical model may be used to generate code in a target language to enable the building of the physical system being designed. The use of the altered IR to generate a new or updated graphical model allows a more efficient and customizable design and simulation process than is typically found by simulating code that has been converted to target languages. The generation of the graphical model based on the altered IR allows a user to visually inspect the changes to the system, and the simulation of the graphical model based on the altered IR allows corrective action to be taken to account for any changes that occurred during the transformation of the model.

Abstract: A device may receive information that specifies a graphical scene. The graphical scene may include a coordinate axis. Data, to be plotted in the graphical scene, may be plotted with regard to the coordinate axis. The device may generate a structured plurality of objects. One or more objects, of the structured plurality of objects, may store properties that define the graphical scene. A particular object, of the one or more objects, may store properties that define one or more elements of the coordinate axis. The device may receive information identifying a modification to an element of the coordinate axis, of the one or more elements of the coordinate axis. The device may modify a property of the properties that define the one or more elements of the coordinate axis, based on the instruction, to implement the modification specified by the instruction.

The heat map may be a graphical interface that includes a graphical representation of the element and a graphical representation of the other element. The device may provide the heat map.
