Of your executing code to a very large memory array, at full speed. Real time trace is one of the most important emulatorįeatures, and is one practically unique to this tool.

Long before engineering delivers prototypes. Operate the emulator stand-alone (without the target) and start debugging code Why wait for the designers! who will likely be late anyway?

Of your entire address space, so you can actually debug much of the code with no Nothing prevents you from mapping emulation memory in place The code wanders off and tries to write to program space, or attempts any sort Many ICEs have programmable guard conditions for accesses Maps logically in place of your system's ROM. ICE's emulation memory is high speed RAM inside of the emulator itself that Many times an hour so it's important to have RAM-like program memory. During a typical debug session we might change and redownload code

Leads to debugging difficulties since it's hard to impossible to download code ROM and to some extent Flash memory for program storage Implement complex breakpoints in hardware, so impose (in general) no performance With Visual C++) offer similar power, but must essentially interpret the programĪt a snail-like pace while watching for the trigger condition. Some software-only debuggers (like that supplied If the program writes 0x1234 to variable buffer, but only if function get_data Hardware breakpoints work in RAM or ROM, Flash or even unusedĬomplex breakpoints let us ask deeper questions of Use the unit's internal magic to compare the break condition against theĮxecution stream. Clearly, it's impossible to debug code in ROM with these.

Replacing the destination instruction by a software interrupt or similar (generally found on BDMs, software-only monitors, and the like) work by

There's an important distinction between the two types ofīreakpoints used by different sorts of debuggers: software breakpoints Particularly useful for stepping through C code. Single stepping, since the processor's single step mode, if any, isn't Emulators also use breakpoints to implement Give you the ability to stop your program at precise locations or conditionsĮxecuting line 51"). For example, youĬan repeatedly access a single byte of RAM or ROM, creating a known andĬonsistent stimulus to the system that is easy to track using an oscilloscope.īreakpoints are another important debugging resource these This makes the ICE byįar the best tool for troubleshooting new or defective systems. However, since the ICE replaces the CPU it generallyĭoes not need working hardware to provide this capability. Resource is target access - the ability to examine and change the contents of Like all debuggers the emulator's most fundamental Work closely with the vendors, all of whom are connections experts Add at least a few days to your schedule to surmount theseĭifficulties. Pitches shrink the range of connection approaches goes up rest assured thatĬonnecting the emulator is usually the most difficult and frustrating part of In other cases the emulator vendor providesĪdapters that can be soldered in place of the target CPU. That clips over the SMT processor, tri-stating the device's core which is then Today we're usually faced with a soldered-in surface mounted chip, soĬonnection strategies are more difficult. Users extracted the CPU from its socket, plugging the emulator's cable in Years ago the ICE physically replaced the target processor. Into the target, while providing a rich set of debugging resources. Your target and your PC, giving you both an interactive terminal peering deeply In a sense the emulator is a bridge between Via one of a number of hardware tricks the emulator can monitorĮverything that goes on in this on-board CPU, giving you complete visibility Tool that substitutes it's own internal processor for the one in your target The In-Circuit Emulator (ICE) is one of the oldest embeddedĭebugging tools, and is still unmatched in power and capability. Resources enjoyed by programmers of desktop computers. Variety of debuggers all let us connect an external computer to the systemīeing debugged to enable single stepping, breakpoints, and all of the debug This magazine is filled with ads from vendors selling quite a wide These devices, to extract the behavioral information needed to find what's Neither terminal nor display (in most cases) there's no natural way to probe I reviewed it here.Įmbedded systems pose unique debugging challenges.
