It allows you to instantly navigate to the definition and references of any symbol. µVision Debugger The µVision Debugger can be configured as a Target Debugger or as a Simulator. It provides a single environment in which you may test, verify, and optimize your application. The Debugger also simulates many ARM-Powered MCUs including their instruction set and on-chip peripherals. Debug Windows The Debugger provides windows and dialogs to help you monitor and control your system. These include: n Memory Window - review and modify memory contents. n Watch Window - view and modify program variables and lists the current function call nesting. n Symbol Window - view debug symbol information of the application program. n Disassembly Window - synchronized with the Source Windows making program debugging easier. n Register Window - view and change register contents. n Call Stack Window - view current call nesting including variable values. n Breakpoints Window - define watchpoints and complex Execution, Access, and Conditional breakpoints. n Browse Window - search for objects in your code. ULINK Debug Adapters The ULINK family of USB Debug Adapters connect your PC's USB port to your target system (via JTAG or SWD), allowing you to debug and analyze embedded programs running on target hardware. The ULINKpro provides unique streaming trace directly to your PC, enabling advanced analysis of your applications such as Execution Profiling and Code Coverage. System Viewer The System Viewer windows display peripheral registers that the processor can read and write to. They display the state, content, and name of peripheral registers. Content values are instantly updated by the target hardware as changes occur. Values can also be changed at run-time by typing a new value from within the System Viewer window. Analysis Tools The advanced analysis tools work with the simulator or with target hardware via the ULINKpro streaming trace adapter. The configurable Logic Analyzer provides a graphical display of signals and variables.You may click on variable changes to display the instructions that caused that change in the source code editor window. The Debugger provides Code Coverage statistics to verify applications that require certification testing and validation. Color coding highlights the execution status of instructions helping you to refine your testing. The Performance Analyzer displays the execution time recorded for functions in your application. Bar graphs display the time spent in a function, and the number of calls to it. The Execution Profiler records execution statistics for each CPU instruction, including the execution count and execution time for each instruction. These can be reviewed in the editor and disassembler windows.

Cortex-M devices with ETM provide instruction trace. The Keil ULINKpro streams instruction trace directly to your PC. This enables debugging of historical sequences, execution profiling, and code coverage analysis. The virtually unlimited stream of trace information enables MDK-ARM to provide complete Code Coverage of your program. Code coverage identifies every instruction that has been executed, ensuring thorough testing of your application. This is an essential requirement for complete software verification and certification. Step source or assembler lines. Data and Event Trace All Cortex-M3 and Cortex-M4 devices provide data and event trace. MDK-ARM provides a number of ways to analyze this information while your system is running: n Trace Window - displays program flow by capturing timestamps, PC samples, and Read/Write accesses. n Debug Viewer - displays the Instrumented Trace (ITM) output in a terminal window. n Exceptions window - displays statistical information about program exceptions and interrupts. n Event Counters - display real-time values of specific event counters providing performance indications. n Logic Analyzer - graphically displays variable changes in captured data trace. Code Coverage shows the percentage of instructions that have executed. ULINKpro allows applications to be run for long periods of time while collecting trace information. This can be used by the µVision Execution Profiler and Performance Analyzer to identify program bottlenecks, optimize your application, and to help locate defects. Data Trace Windows provide information from the running target for program data, exceptions, variables, and printf-style outputs 4 MDK-ARM Microcontroller Development Kit The performance analyzer displays time spent in each part of your program. RTX Real-Time Operating System RTX Real-Time Operating System RTX Real-Time Operating System Today, microcontroller applications often require simultaneous execution of multiple tasks in a real-time environment.
