A mechanism is provided in a debugger for building a file information database while significantly reducing debug startup time. For each line number table, the mechanism of the present invention reads the header section and determines all the source files that contribute to the line number table. The mechanism also makes note of the line number table offset. The mechanism then inserts the source filename into the file information database. In one preferred embodiment, the file information database is implemented as a hash table. Searching time occurs during an interactive debug session; therefore, the searching time is not easily detectable to a user, thus creating the perception of a faster interactive debugging session.

An operating system including a software development environment is programmed into the on-chip flash memory of a system-on-a-chip type microcontroller. The software development environment is configured to reside entirely in the microcontroller's on-chip flash memory and includes an editor, a line-by-line bytecode compiler, a flasher, and an interactive debugger. A user operating a terminal emulator on a host computer connects to the microcontroller chip by means of a serial (USB) connection based on an FTDI protocol, or other serial link, in order to develop a BASIC program for the embedded system. The operating system is configured to permit external I / O pins on the microcontroller chip to be mapped to special “pin variables” for manipulation or examination by the user program, and to manage internal peripherals (timers, UARTs) of the microcontroller chip so as to permit application-level interrupt handling.

A development application leverages the programmability of shader execution units in the graphics processing subsystem to make graphics processing subsystem state data accessible to applications executed outside the graphics processing subsystem. The development application modifies shaders to include state output instructions adapted to direct a shader execution unit to copy graphics processing subsystem state data to a location in the computer system that is accessible to applications executed outside of the graphics processing subsystem. Following the execution of the state output instructions, the shader execution unit can be halted or can continue executing the shader. The development application can modify the shader to include state restoration instructions adapted to direct the shader execution unit to set state data of the graphics processing subsystem to previous or new values. The development application can dynamically modify shaders with state output and restoration instructions to update state data of the graphics processing subsystem.

An interactive system for debugging programs in which a persistent data base system responds to update queries containing debugging information from a debugging information source and to read queries on the debugging information from an interactive interface. The interactive interface produces the read queries in response to inputs from users and formats the results of the read queries as required by the user. One source of inputs is a standard Web browser for which the interactive interface functions as a Web server. The system also includes a command channel by which the source of debugging information receives commands from the interactive interface. In one embodiment, the command channel is implemented in the data base. In a disclosed implementation, the source of debugging information provides memory debugging information. Also disclosed are techniques for using an automatic memory management system to reduce memory fragmentation and heap footprint size.

A test system that enables real-time interactive debugging of a device under test (DUT) using native customer code. A translation module may format, in real time, debug commands, corresponding to a user input, into a format recognizable by instruments in a tester. The user input may be a test program or test instructions written in a high-level programming language. The translation module may translate the user's debug commands into lower-level test instrument commands, based on which the tester may apply control signals to a processor in the DUT to test subsystems of the DUT. A result of the test may be provided to the translation module, which may, in real time, format another debug command, or provide an indication of the result to the user. The translation module may thus enable a user to step-through and modify native customer code in an interactive manner to debug a DUT.

Systems and methods are disclosed for performing interactive debugging of shader programs using a non-preemptible graphics processing unit (GPU). An iterative process is employed to repeatedly re-launch a workload for processing by the shader program on the GPU. When the GPU encounters a hardware stop event, such as by reaching a breakpoint in any thread of the shader program, encountering a hardware exception, or failing a software assertion in the shader program, the state of any executing threads is saved, graphics memory is copied to system memory, and any currently executing threads are killed to enable the GPU to process graphics data for updating a display device. Each pass of the workload may result in incrementally more data being processed. In effect, the changing state and variable data resulting from each pass of the workload has the effect that the debugger is incrementally stepping through the shader program.

An apparatus for debugging source code includes a source code debugger configured to display state information and one or more initialization routines corresponding to a particular software function. The initialization routines initialize a target environment to a particular system state and facilitate replication, isolation, and analysis of software coding errors. In one embodiment, a function selector facilitates selection of the target function by a user and generates an execution request. In turn, a task dispatcher dispatches the initialization routines and associated software function in response to the execution request. The present invention greatly simplifies interactive debugging of source code. Rather than generating complex, error-prone, and often timing-dependent manipulation sequences of registers, memory, peripheral devices, and the like, a user simply selects the initialization routines that generate the particular states and conditions necessary to replicate and analyze a particular software error.

An improved method for debugging of analog and mixed signal behavioral models during simulation using Newton-Raphson iteration replay. The method according to the invention has substantially modified the prior art solution by limiting the interactive debugging steps in a replay of the last iteration of the accepted timepoints. Using this method, the user only interacts with the simulation during the iteration replay, and only for the accepted solution points. If the user is single stepping through this simulation, the simulator enters interactive mode at each statement during the replay. Similarly, if not single stepping, but a breakpoint has been triggered, the simulator enters the interactive mode at the appropriate statement to honor the breakpoint. While the iteration replay is performed, the system of equations does not need to be solved again. Instead, the solution vector is reinstated from the known solution of the last iteration.

In a method-centered view, an arc is shown between a node representing stack frames of a selected method and a node representing adjacent stack frames. The graph can be based on call stacks of all tasks or all threads, or based on call stacks of tasks or threads flagged by a user. Stack frame, thread, and / or task details are also displayed.
