Abstract: A computer implemented method for debugging of a program may include parsing a code segment of the program, the code segment invoking one or a plurality of execution events during an execution of the program to derive a plurality of questions, each relating to an execution event of said one or a plurality of execution events, based on the parsing of the code segment and on information recorded during the execution of the program. The method may also include selecting one of the questions as a current question. The method may further include presenting in a user interface the current question with one or a plurality of causes related to the current question, and one or a plurality of other questions of said one or a plurality of questions for selection by the user.

Abstract: A system and method are provided for enhanced navigation along execution time and code space in a debugger to assist a user in remediating errors, streamlining, or reverse engineering a computer program and the source code thereof. Snapshots of system states are recorded, a causality tree of commands is constructed through execution of the program to be debugged, and an intelligent display of system states captured during runtime and indexed or cross-referenced by time are displayed to the user in an intelligent manner to aid the user with certain debugging tasks. Additionally, further features in assisting the user to locate a root cause of an error or unexpected value and remediate that cause are also provided.

Abstract: A method for automated debugging of a design under test (DUT), including using a processor, (a) identifying a value of a signal at a specific time instance in which a user has indicated interest; (b) performing driver tracing based on structural analysis and signal analysis to determine one or a plurality of drivers of the identified value in the signal; (c) if the driver tracing returns a single driver of said one or a plurality of drivers, presenting the returned single driver to the user via an output device; and (d) if the driver tracing returns a plurality of drivers of said one or a plurality of drivers, performing formal analysis on a compiled sub-structure of the DUT to which all of said returned plurality of drivers are related to determine a single driver from said returned plurality of drivers, and presenting the determined single driver from said returned plurality of drivers to the user via the output device.

Abstract: A system and method that implement an object-oriented model for requirements of a hardware design in order to verify the design. The object-oriented model abstractly captures the design topology, capability, control, and status of the design. An object-oriented model or definition of a hardware design is based on one or more specifications or standards implemented with the design. With the object-oriented model, a system and method for storing and displaying data captured during a test run is implemented. Graphical displays are defined to show run information for abstract objects of the design. Predefined graphical displays may be altered to accommodate the features of the object-oriented model and new graphical displays may be defined for objects in the model.
Abstract translation: 为了验证设计，实现了硬件设计要求的面向对象模型的系统和方法。 面向对象模型抽象地捕捉设计的设计拓扑，能力，控制和状态。 面向对象的模型或硬件设计的定义基于通过设计实现的一个或多个规范或标准。 使用面向对象的模型，实现了在测试运行期间捕获的数据的存储和显示的系统和方法。 图形显示被定义为显示设计的抽象对象的运行信息。 可以改变预定义的图形显示以适应面向对象模型的特征，并且可以为模型中的对象定义新的图形显示。

Abstract: The present disclosure relates to a system and method for capturing log messages in a post-processing debugging environment. Embodiments may include receiving a processor model associated with an electronic design and generating, using one or more processors and the processor model, a complete view of the state of the memory. Embodiments may further include writing, using one or more processors and the processor model, a log message whenever a designated message logging function is reached within the complete view of the state of the memory.

Abstract: A computer implemented method of debugging with enriched message log capability may include, for each instance during an execution of a program to be debugged in which a message is issued, automatically analyzing the program code included in a scope of the program relating to the message to identify one or a plurality of variables. The method may also include saving on a non-transitory computer readable storage medium a value at that instance of each of said one or a plurality of variables. The method may further include causing a message log that includes the message to be presented on a display device, associating the value of each said one or a plurality of variables with the message.
