EMU3 Advanced breakpoints What are they for ?

They permit intricate debugging by allowing user to setcomplex breakpoints and to control trace and triggers onpredefined events.

Main features:The Advanced breakpoints feature is a configurable 4-levelstate machine which is executed at micro controller speed.

Each level can specify up to 4 events, hence a user canchoose to follow a series of up to 16 logical events.

Actions may be performed upon the occurrence of the definedevent or sequence of events.

Any user configuration can be saved as a *.bem file and bere-used for any other workspace

8/13/2019 1143451287

11/50

EMU3 Advanced breakpoints: Definition(1/3) Events can be defined using any of the following

parameters:

a specific address or range of addresses,a specific data value with bit mask,a read, write or read/write access,

an opcode fetch,external event(s) monitored using one or all of thenine input triggers, trace full information,

a DMA memory access,an interruption,a stack operation access.

8/13/2019 1143451287

12/50

EMU3 Advanced breakpointsDefinition (2/3)

Actions can be defined as:a break in the execution of the program (i.e. a

breakpoint),the enabling, or disabling of trace recording,the recording of a snapshot in the trace,

continuing to another level of conditions, defined byanother event or series of events,the outputting of a waveform to one or both of the

two output triggers,a set of the above actions.

8/13/2019 1143451287

13/50

EMU3 Advanced breakpointsDefinition (3/3)

Levels can be defined as:The level defines the relationship between these events(i.e. specific, user-defined conditions) and the actions tobe carried out by the debugger. A counter may also beset.The definition of each level has the following structure:

IF [NOT] [[NOT] ]

THEN actions

ELSE IF [NOT] [ [NOT] ]

THEN actions

Combination operators: AND, NAND, OR, XOR, NOR,XNOR

EMU3 Advanced breakpointsExample

Break on memory accessTo set a breakpoint on memory access (either a read ora write) within a specific range of addresses . This sort ofbreakpoint is very useful if you wish to ensure that certainmemory zones are never read or written .

To set a breakpoint on the reading or writing of aparticular data value to a particular memory address orrange of memory addresses.This Break on are useful after function call

IF (opcode fetch at main.c*57)THEN Goto Level 2;

LEVEL 1:

IF (access at memory location [0x40] with data=0x05)THEN break;

LEVEL 2:

(empty)LEVEL 3-4:

ON or OFFSTART with TRACE

8/13/2019 1143451287

16/50


Synchronize an external deviceSometimes it is useful to send a pulsed signal from oneof the output triggers to synchronize an external deviceupon the occurrence of a particular event. For example,say that you wish to synchronize an oscilloscope upon

the occurrence of an entry into an interrupt loop (or aspecific task in a function).

IF (opcode fetch in task,,IT,,)THEN (Trigger 1 Pulse);

LEVEL 1:

(empty)LEVEL 3-4:


8/13/2019 1143451287

17/50


Synchronize trace with an external eventsSometimes it is useful to observe data or code after anexternal event (ie:a signal change on the applicationboard). For example, you wish to measure the latencytime between a port (input) change and the functiontreatment.

IF (access at memory location [0x40] with data=0x05)THEN TRACE break;

LEVEL 2:

IF (Trigger in =1)THEN (TRACE

Goto LEVEL2);

EMU3 Advanced breakpoints Saving and loading advanced breakpoints

You can store the definition for your advanced breakpoint to a file(*.bem ), which can be reloaded by any STVD7 project, so long as youare using the EMU3 emulator to debug the application. This will allowyou to save time if you have toswitch between advanced breakpointswhile debugging your application.

Help for advanced breakpoints on STVD7Open the Search window by selecting, from the main menu, Help>Search , or by clicking on (Search in Help, or Help Home Pageicons) in the Emulator toolbar, and then type bem in the keyword

field of the search folder

8/13/2019 1143451287

19/50

EMU3 Advanced breakpoints

Timing limitations Advanced breakpoints take time to be evaluated andtriggered.Trace timestamp counter runs at 20Mhz internal clockor user-specified external clock and hence has a timebase which differs from Advanced Breakpoints.Trace timestamp counter is a 30-bit counter (107 374182 350 ns) whose reset means a change in referencepoint for timing calculations.

Emulator update Emulators contain firmware that may be updated When the EMU3 is initialized

STVD7 checks the firmware versions

If needed, the user is prompted for automatic update

EMU3 DISCREPENCIES

Emulator/Emulator discrepencies menu displays thedifferencies between the emulation system and thetarget MCU as they are different for each target andemulator type (emuchip or ELPD)

MDT10 emulator is EPLD based so parametrics aredifferent for instance (ADC conversion time, RCcalibration not feasible as emulated by a fixedfrequency from an oscillator, analog comparator not

emulated, )
