| ST90158-EMU2 ST9 HDS2V2 EMULATOR FOR ST90158 DOC-ST90158-EMU2/DS EMULATOR DESCRIPTION s Emulator composed of: - a mainboard included in a box powered by an external power supply - a ST90158 specific probe - a Windows based GNU debugger software running under Windows-3.1x / 9x / NT4.0 Emulator connected to the user application through the probe: - ST90158-EMU adapts to QFP80 or LCC84 package Emulator connected to a host PC or compatible with a standard parallel cable 3V or 5V +/- 10% operating voltage Up to 16 MHz internal clock operation at 5V and 14 MHz at 3V HARDWARE FEATURES s Clock source selectable: - 4 MHz oscillator on probe - 8 MHz quartz on probe s s s - TTL source from application Application power up detection 9 external input triggers: - 1 input trigger on subclic connector - 8 input triggers from analyser probe 2 output triggers (TTL levels) s s s s Rev. 2.0 July 1998 This is preliminary information on a newproduct in development or undergoing evaluation. Details are subject to change without notice. 1/4 1 ST90158-EMU2 DEBUGGING FEATURES Mapping s Accessible memory segments in the emulator: all ST9+ segments (21h is reserved). - ROMs are emulated with on-emulator memories - RAMs are emulated with on-emulator memories - external memories are either emulated with on-emulator memories (full space ST9+) or accessed by the emulator on the application board (size of one segment only) s Granularity of 32 bytes s Write or non existing protection mechanism Instruction Breakpoints s Unlimited on the whole memory space s Program stop on specified instruction fetch at C or assembler level s Can be associated with a counter or/and a condition (loss of real time operation) Register Breakpoints s 2 register events defined by register number, register page (if any), data value with bit mask s Read, write, or read/write access conditions s Can be used: - independently to generate up to 2 breakpoints - to define one range of register to generate 1 breakpoint - combined with AND or THEN condition to generate 1 breakpoint Advanced Breakpoints s 4-level sequencer that enables to perform actions when specified event or events sequence occur s Each level is defined by: IF s value with bit mask, read, write or read/write access, opcode fetch - external events using the 9 input triggers - trace full information - any combination of the above listed inputs Actions can be: - to stop the program execution - to output a waveform on one or both of the 2 output triggers - to enable, disable the trace - to record a snapshot in the trace - to go to another level - a set of the above actions Trace s Trace contents disassembled at source level, optionally interleaved with machine instruction and buses activities s Recordable trace in a text file s 64K-word trace records composed of: - memory segment number, address, data and control buses activities - 8-bit analyser probe - 1 trigger input - 30-bit timestamp extendable by overflow counting. Timestamp clock is device clock source or fixed 20 MHz reference - advanced breakpoint sequencer information s Selective trace defined by events in the sequencer: - trace on - trace off - snapshot - programmable trigger position in the trace record Performance Analysis s Real-time counting of time spent between 2 specified instructions s 48-bit wide count based on timestamp clock s Up to 32K executions recorded for the couple of instructions s Time analysis giving average time, minimum time, maximum time, standard deviation s Graphically displayed results s s s Logic_operator1 or logic_operator2 are one of AND, NAND, OR, NOR, XOR, XNOR Only one level is active at the same time 2x16-bit counters available per level (one for IF, one for ELSIF condition) Events can be: - memory events defined with address, data 2/4 2 ST90158-EMU2 Freeze Peripherals when program execution is stopped s Individual selection to enable/disable freeze function for: - Watchdog Timer when used as Timer - Standard Timer - Multi Function Timer0 - Multi Function Timer1 - Multi Function Timer3 s Watchdog always stopped when program is stopped s ADC always stopped when program is stopped Code Debug s Full C source level and/or assembly level debugging capabilities s Display of source code in concurrent windows s Disassembling capability, optionally with interleaved source lines and ST9+ instructions, with symbolic and/or hexadecimal instruction operands s Log file feature, allowing storage and subsequent redisplay or re-use of all displayed information s Command files capability, which may be executed at user's request or automatically interpreted at start-up Display and Modification Capabilities s All variables, taking into account the exact structure declared in the source code s C-like expressions (display only) s The entire ST9+ memory structure s All ST9+ registers s The ST9+ system registers: - stacks - working registers - flags s Stack showing current function calls for each stack level and their parameter values (display only) Running Features s Execution starting from reset entry point, or from the current position in the user program s Single stepping capabilities: - at source code level - at ST9+ machine instruction level s - entering in interrupts or not Function call or a macro reference may optionally be considered as a single instruction depending on the level of detail required Debugger Customising: s Last working environment restored automatically for a given application: - number of windows opened - windows position - breakpoint lists s Working environment storage in personalization files capability Help Files s Full on-line help following Windows standard help facilities s Context-sensitive accesses from any window s Keyword search facility Debugger based on GDB technology s Line mode accessible, with access to all GDB commands 3/4 3 ST90158-EMU2 Notes: Information furnished is believed to be accurate and reliable.
