Abstract: Systems and methods are provided for a scheme and mechanism for performing static analysis of a sample time aware state diagram model to compute and propagate multiple samples rates associated with the state diagram model. A graphical intermediate representation of the state diagram model, such as a directed graph or control flow graph, is used to determine how the multiple sample rates are propagated via elements of the state diagram model. The graph provides a static representation of the control of flow, including alternative and/or conditional flow paths, of the state diagram model. The present invention determines the propagation of sample rates via analysis and traversal of the intermediate representation. By using the techniques of the present invention, a state diagram model may provide multiple sample rate outputs, such as by function calls and output signals to a graphical model, such as a model representing a dynamic system.

Abstract: A computing device may be configured to receive a design. The computing device may further receive a requirement object that represents a requirement for the design. The requirement object may include a first functionality and a second functionality. The computing device may interact with the design using the requirement object. When interacting with the design, the computing device may invoke the first functionality to determine whether the design satisfies the requirement and invoke the second functionality to provide a result of invoking the first functionality.

Abstract: A computing device may be configured to interact with a requirement object using an object-based requirements framework. The computing device may further provide a design to the object-based requirements framework. The design may comply with design criteria of the object-based requirements framework. The computing device may also determine whether the design complies with the requirement object. The determining may be based on the interacting, and may produce a result.

Abstract: The described embodiments present techniques for recovering from syntax errors. These techniques correct potential errors while preserving the shape of the parse tree, and the specific implementation of the techniques can be automatically generated from the grammar. These techniques may operate by looking back at states associated with previously-received tokens to determine pair matching status, when a synchronizing symbol is received. The techniques can respond to the pair matching status determination by potentially adding a synthesized token or by deleting a token that has already been received. The techniques may use a structure referred to herein as a tuple to assist with the evaluation of the pair matching status. Some of the techniques utilize indentation information to evaluate the pair matching status, while other techniques ignore such information. The described embodiments also include a technique for automatically generating the tuples from a set of grammar rules associated with the parser.

Abstract: A system and method automatically inserts pipelines into a high-level program specification. An Intermediate Representation (IR) builder creates one or more graphs or trees based on the high-level program specification. A scheduler iteratively applies a bounded scheduling algorithm to produce an execution schedule for the IR minimizing overall execution time for a given number of pipeline stages. A Hardware Description Language (HDL) code generator may utilize the pipelined, scheduled IR to generate optimized HDL code corresponding to the high-level program specification. An annotated version of the high-level program specification showing where the pipelines have been inserted may be displayed allowing additional design exploration.

Abstract: A system and method determines the differences between versions of an object, such as a file. The object versions are compared using a differencing tool to identify the differences between the versions. A scoring algorithm may be selected for the object based on one or more attributes of the object. The scoring algorithm is used to compute a difference score for the object. The difference score may be a function of the differences between the object versions and the characteristics or qualities of those differences. The difference score provides an indication of the relative importance of the changes made to the object. The difference scores from multiple objects may be presented in an interactive report, and sorted to identify those objects that underwent the most significant or noteworthy changes.
