These fall into three categories. Memory and code correctness checking tools, high level language application debug tools and system software debuggers. The latter two are focused on real-time debug of software stack components. A forth type of debug tools that has found new life because of the complex interactions in heterogeneous multicore SoC chipsets is the instrumentation based event tracing utility. Intel System Studio offers the GNU Project Debugger for application debugger and the Intel JTAG Debugger as system debugger. SVEN – ultra-low overhead instrumentation technology for software debug is also included.
