  Introduction
The FIRE-EMUCON is the universal emulation system for all FIRE emulation probes.

The system includes the general emulator functions like trigger system and runtime control system.

The trigger system enables complex trigger functions on address breakpoints, on events and external signals. An trigger output for external DSOs or logic analyzers is available.

An analyzer system with 160 trace channels, time stamp and performance analyzer capability is included in this module.

In-Circuit Emulator


    Most Emulation Functions can be used while the target CPU is running ('on the fly' operation)

    Two Emulator Operating Modes
  • Stand Alone Mode
  • Active Mode

Symbolic Debugging

    A hierarchical symbol database enables structured symbolic debugging. Symbol names can be up to 255 significant characters long and can be used to show single program addresses, module names and memory classes. The disassembler can use the symbols for labels and/or operands. Demangling for C++ signatures is supported.

High-Level Language Debugging

    TRACE32 can directly load the output of all standard compilers for C, C++, Pascal, Modula2, PEARL and ADA from most compiler vendors. Program display and debugging can be done in assembler, high-level or in a mixture of both. It is possible to construct both assembler and high-level windows on the screen simultaneously. All variable types specific to the high-level language can be displayed and modified. Addresses can be absolute, relative or line number based.

Multitask Debugging

    The TRACE32 multitask debugger supports all common RTOS. The multitask debugger supports symbolic debugging of complex multitask applications and the detailed analysis of the real time behaviour of the system.

Runtime Analyzer

  • Program runtime is recorded automatically.
  • Time from initial start - 300ns to 300 days
  • Time from the last program stop - 100ns to 300 days
  • Time difference between 3 reference points - 300ns to 300 days
  • Timers can be checked at any time

Edit/Debug Link

    The editor window can be synchronised to the debugging window so that when an error is found, the source text can immediately be shown and if required, edited.

On-Screen Assembler

    The on-screen assembler is provided in addition to the more common inline assembler found on other systems. With the on-screen assembler, short programs can be written quickly and reliably. It is not a full assembler whose output code is linkable to the main program in the usual way.

Up to 16 MByte Emulation RAM

    To store programs in the emulator during the development phase, the emulator provides up to 16 Mbyte overlay memory. This memory can be static SRAMs with an access time of down 3 ns. (typ 10 ns).

Dual-Ported Access to all Emulation Memory

    The whole emulation memory system is dual-ported. This allows the emulator to read or write memory while the target system is running in real-time e.g. to show variables, port contents etc. For low to medium CPU clock frequencies there is no decrease in performance of the target system due to the operation of the dual-port access mechanism. At higher CPU clock frequencies, the performance may be slightly reduced in accordance with the number of accesses made by the control system. The dual-port access mechanism can be switched off, but if this is done, then memory access by the emulator can only take place when the target program is stopped.

Selective Mapping of Memory Classes

    The address mapper can segment the memory into 4 segments. By using this segmentation, it is possible for example to split the memory so that a PROGRAM area can be mapped to the emulator RAM while the DATA area remains mapped as target memory. It is also possible to have totally separate physical memory areas displayed simultaneously.

Flash Programming

    TRACE32 supports the programming of external flash memory as well as the programming of internal flash memory of microcontrollers. The programming can be controlled by the emulator or by a routine in the target system.

Memory Oriented Breakpoint System with up to 16 MByte Breakpoint Memory

    Most currently available emulators use multiple address and data comparators to form the breakpoint system. This technique not only restricts the number of breakpoints available it also means that systems using bank selection are difficult to support. The breakpoint memory on the TRACE32 is basically a bytewide memory structure that can be mapped in a similar way like the overlay memory. When any memory location is accessed, the corresponding breakpoint byte is also accessed so that there are effectively 8 kinds of breakpoints for each addressable location. The break memory is dual-ported, so that breakpoints can be set and displayed while the system is running.

9 Breakpoint Types

  • Program Breakpoint
  • Spot Breakpoint
  • Data Read Breakpoint
  • Data Write Breakpoint
  • General Purpose Point A..E In each group there are up to 16 million breakpoints available depending upon the amount of breakpoint ram in the emulator. Breakpoints can be specified as a single address or an address range.
  • Support for On-Chip Breakpoints
  • On-Chip breakpoint system are used to generate hardware breakpoints.

Flag System

    In a special memory, all addresses which are read or written are marked with read or write flags. This memory can therefore supply a lot of important information:
  • Systematic program test due to the fact that each executed module will be marked in the flag ram.
  • Detection of unused or unexecuted code.
  • Systematic system test through visible code coverage analysis.
  • Detecting accesses to unused or illegal address locations.

Bus Trigger System

  • Trigger interactions with other TRACE32 systems
  • Change trigger polarity

Strobe Monitor for Target System

    If the strobe period becomes >10ms the system will alert the user. If programmed to do so, the emulator can go into a standby mode if this occurs.

Internal Frequency Generator

  • Variable VCO with frequency range from 1 to 150 MHz.
  • Emulation CPU clock frequency programming is done via the emulation control unit.

Trigger Unit


Main Trigger Unit with 4 Levels

    The level structure of the trigger unit allows very flexible trigger combinations and sequences in consecutive and nonconsecutive order. Each level has the same priority and the same capabilities. A trigger program defines, under which circumstances a level can be reached or left, and therefore which trigger conditions or operations are the current or the next.

Analyzer Programming via a special Window

    The programming of this complex trigger unit is done in an assembler like language for maximum flexibility. Using this language, the programming of very complex trigger sequences or operations can be defined. For simple demands, a pull down menu improves the programming for beginners.
