摘要： 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.

摘要： A modeling system includes a graphical programming environment that receives a first graphical model from a user. The system may also receive a configuration control set for the first graphical model. A code generation engine converts the first graphical model into an intermediate representation (IR). A second graphical model is created from the IR and the configuration control set. The second graphical model is displayed to the user, and may be subject to one or more modifications. Code in a target language may be generated from the second graphical model.

摘要： Methods and systems for providing a synchronous model in a modeling environment are disclosed. The predetermined operations of the model, such as a transition to a state in a state-based modeling environment, are implicitly synchronized with a signal selected by users, such as a clock signal. The predetermined operations of the model may be synchronized on a rising and/or falling edge of the clock signal. The synchronization of the operations is guarded in which the predetermined operation of the model occurs only on the synchronization signal selected by the users while other operations may occur at any time when the model is activated.

摘要： Exemplary embodiments allow configurable execution of operations associated with a state enabled system in a graphical modeling or graphical programming environment. In an embodiment, a state enabled system may be identified in a graphical model, or a graphical program, or both. The state enabled system may be associated with a first operation and a second operation, and may include instructions to execute the first and second operations. The state enabled system may be configured to always execute the first operation regardless of an enabling condition. The state enabled system may also be configured to prevent an execution of the second operation unless the enabling condition is satisfied.

摘要： Embodiments of the present invention allow user to generate a model in a modeling environment and to generate code from the model using various implementations of code for portions of the model. The implementations of code can be supplied by the modeling environment or supplied by a user. Embodiments further allow a user to specify a scope in a model such that portions of the model contained in the scope use a specific implementation or implementations of code.

摘要： The present invention provides a method and system for automatic verification of automatically generated standalone code intended for execution on a target computing platform against its original design simulated in a simulation environment. The present invention also applies to execution comparisons between two implementations, such as two simulations, one simulation and one standalone code implementation, or two standalone code implementations. Block diagrams can be used to create a comparison model that compares two implementations. The comparison of different implementations can be performed at a block level, a subsystem level, a model level, or multi-model level. The present invention allows automatic comparison once a user supplies the intermediate outputs and/or signals that the user wants to compare and monitor. Reports can be generated to show the statistics of the comparison results.

摘要： An algorithm and architecture are disclosed for performing multi-argument associative operations. The algorithm and architecture can be used to schedule operations on multiple facilities for computations or can be used in the development of a model in a modeling environment. The algorithm and architecture resulting from the algorithm use the latency of the components that are used to process the associative operations. The algorithm minimizes the number of components necessary to produce an output of multi-argument associative operations and also can minimize the number of inputs each component receives.

摘要： A system and method automatically generates an object-oriented, textual program from a graphical model, and verifies the performance of the textual program as compared to the graphical model. The graphical model may have a plurality of interconnected blocks, and each block may have a plurality of parameters. One or more of the blocks are mapped to a system object, and the block's parameters are mapped to properties of the system object. An object-oriented, executable textual string is generated automatically for the block. The generated string includes at least one command to: instantiate a system object having functionality that matches the block; set one or more properties of the system object based on the block's parameters; and run the instantiated object.
