Simulator Debugger for M16C Series and R8C Family [for High-performance Embedded Workshop]

This product is a simulator debugger which allows you to run and evaluate your application program without any target hardware on Renesas integrated development environment "High-performance Embedded Workshop". It provides a source-level-debugging environment with abundant break features and advanced functions such as coverage measurement and virtual interrupts. In addition, its user friendly interface and multi-window (overlappable) will offer stress-free debugging environment.

This product is a component of the C/C++ Compiler Package for M16C Series and R8C Family [M3T-NC30WA]. Installing the compiler package allows to debug using this simulator debugger under a High-performance Embedded Workshop environment (Renesas IDE).

Functions

[Basic Functions]

Register WindowDisplays/changes content of flags and registers particular to the MCU.
Memory WindowDisplays memory content together with the address and label. Display format can be selected from among binary, decimal, hexadecimal, ASCII, SJIS (for Japanese) or JIS (for Japanese) .
RAM Monitor WindowDisplays memory content changed during target program execution. The area read during program execution is displayed in green, and the area written is displayed in red. (You can set colors of your choice.)
ASM Watch WindowMonitors changes in memory content and variable content declared on the assembly language level. Display format can be selected from among binary, decimal, and hexadecimal. If the specified address is within the real-time RAM area, the area read is displayed in green, and the area written is displayed in red. (You can set colors of your choice.)
C Watch WindowDisplays C/C++ variable contents. In addition to a window that displays variable formula of your choice, there are windows that display external variables, local variables within a file, and local variables within a function.
Stack Trace WindowDisplays function call information of C/C++ language.
Script WindowWindow for executing commands from the keyboard or script files. An area is provided for displaying command execution results and command history. Execution results can be output to a file.
S/W Break Point Setting WindowEnables set / cancel the software break points. You can set up to 64 break points (OR condition).
H/W Break Point Setting DialogEnables set / cancel the hardware break points. You can set up to 64 break points (OR condition).

[Advanced Functions]

I/O Timing Setting Window

Inputs/outputs to a port, and sets/displays interrupts. It is also possible to check cycle-by-cycle data input, definition of interrupt, and change of output data.
And, a timer interrupt occurrence at time intervals in units of msec/µsec is enabled. (Note that the CPU operating frequency need to be specified.)
Besides, there is the I/O script function that can simulate peripheral I/O (timer, analog to digital converter, etc.) operation. By registering I/O script of peripheral I/O (written in script format in a file) in the I/O window, you can simulate operation of that device.
For example, to simulate timer operation, register the following script with "while" and "if":

 

[I/O script defining example of timer operation]

 {
  while(1){
    if( ([0x380].b & 0x01) == 0x01){
      ; Down count of Counter
        waitc [0x386].W + 1

      ; Timer interrupt occurs
        int 21,[0x55].b & 0x7
    }else{
        waiti 100
    }
  }
 }
GUI I/O WindowWindow for creating key input panels or output panels for the user target system by simple mouse operation.
[Input panel]
You can define operation of data input or interrupt for the created keys. Pressing the key while the program is running generates data input or interrupt.
[Output panel]
You can display by LED or label according to the value of the output data.
Output Port WindowPrints a result of output using the printf() function to the window or a file.
Trace Point Setting WindowSets/cancels trace points. Can set 6 trace points maximum and specifies the combination condition of trace events. For starting and stopping events for tracing, either memory access (read/write) or instruction execution is specifiable. As a combination condition, there are AND and OR.
Trace WindowDisplays the results of tracing. The following three display modes are supported: Bus mode, Disassemble mode and Source mode.
Data Trace WindowGraphically shows the data access information on the results of tracing.
Coverage WindowShows coverage measurement results of C/C++ language functions. Start/end addresses and coverage can be checked. Double-clicking the line to be checked opens a coverage source window to show executed/unexecuted in a line of source.
MR WindowShows the state of the real-time OS M3T-MR30.
MR Trace WindowGraphically shows task execution histories of programs using the real-time OS M3T-MR30. Also, each history of interrupt handling and system call issuing is shown together.
MR Analyze WindowShows the results of statistical processing of measured data in the range specified with the MR trace window. And shows the list of the following records : the occupation status per interrupt handler or task, history of system call issuing.
Task Trace WindowGraphically shows task execution histories of programs using real-time OS.
Task Analyze WindowShows the results of statistical processing of measured data within the range specified with the Task Trace Window. This window shows the occupancies of tasks in a CPU.

Specifications

I/O simulation Data can be input/output cycle-by-cycle.
Interrupt simulation Interrupt occurrence in units of cycles or time (msec/µsec) is enabled.
Execution time measurement Execution time is worked out by the CPU operating frequency and the number of CPU execution cycles. *
Tracing feature Trace logging up to 256K cycles is possible.
RAM monitor display Any 1K byte of memory is displayable.
Coverage measurement Coverage of all memory area can be measured.

* It's possible to select the cycle accuracy mode which measures the cycle counts extremely precisely.
