Overview
Description
This simulator product makes source level debugging of applications possible in the Renesas integrated development environment, or the High-performance Embedded Workshop, while the target system is not available on hand.
The simulator debugger's exclusive functions (high-function debugging) permits the programs written in C/C++ language or assembly language to be debugged efficiently while the actual MCU is not available on hand.
- High-accuracy simulation[Cycle accurate]
- Simulated I/O function[Standard and file input/output functions usable]
- Virtual interrupt function[Simulation of interrupt operations possible.Virtual interrupts using arbitrary timing and break conditions.Timer module based internal interrupts possible]
Furthermore, an intuitively understandable easy GUI (graphical user interface) provides a comfortable debug environment.
This product is included in the C/C++ Compiler Package for RX Family (for High-performance Embedded Workshop environment). When the compiler package is installed, the functions of this simulator debugger are added to the High-performance Embedded Workshop environment.
Features
- Since the simulator/debugger runs on the host computer, the user can start debugging the program while the actual MCU is not available on hand. This will result in a reduced development period of the entire system.
- The number of instruction execution cycles is calculated by simulating. This enables performance evaluation even in the absence of the actual MCU.
- The functions outlined below are available, which permit program test and debug to be proceeded efficiently.
- If an error occurs while the program under debug is running, the user can choose to continue ignoring the error or stop the program.
- Get profile data and measure performance one function at a time.
- Comprehensive break functions (virtual interrupt operations also possible).
- Set and edit memory map.
- Display a history of function calls.
- Display C/C++ and assembler source level coverages.
- Visual debug function based on image and waveform display.
- The simulator/debugger runs under Windows, allowing breakpoints, memory map, performance and trace to be set in dialog boxes. The environment setup suitable for the memory map of MCU in the RX Family can also be set in a dialog box.

[Functions Supported by This Simulator Debugger]
- All executable instructions
- Exception processing
- Registers
- Entire address space
- Peripheral function(Timer) (Note1)
Note
- Support for the CMT-related features in the interrupt controller (ICU) and a total of four compare match timer (CMT) channels, i.e. two CMT units (unit 0 and unit 1), each with two 16-bit timers.
[Functions Not Supported by This Simulator Debugger]
- Low power state (Note1)
- Non-maskable interrupt (NMI)
- Reception of an interrupt during execution of any of the following instructions (Note2): RMPA, SCMPU, SMOVF, SMOVB, SMOVU, SSTR, SUNTIL, SWHILE
- Values in memory and registers that become undefined after the execution of instructions
- Lower-order 16 bits of the accumulator (ACC)
Notes
- Simulation is stopped on the execution of a WAIT instruction.
- The interrupt is accepted when execution of the instruction is completed.
Note: Use an emulator to debug these functions.

I am new to Renesas, HEW and the RX MCU. I am using HEW 4.09.01 with C/C++ compiler for RX family V 1.02 and RX family Simulator Debugger V 1.02.01. I have written a library, and imported it into an application. Because of ...
Oct 19, 2017 - S7G2 SK: Porting to ThreadX
We are planning to port our c/c++ library to ThreadX. As a first step, we are getting familiarized with e2 studio. In this regard, we have the following queries. 1. How to install a S7G2 SK simulator/emulator for debugging?
Oct 24, 2023 - Program in C Language without RPDL ?
Hy, I would like to know if it possible to make a program, using C Language, without using the Renesas Peripheral Driver Library ? I tried to use the CMT with declaration like : #pragma ADDRESS CMSTR0_ADDR 0x88000 // Compare Match Timer Start Register 0 struct bit2_def { char ...

- How will I know the number of cycle of code execution has been generated?
The execution cycle count can be measured in the simulator environment. If you are using the High-performance Embedded Workshop:Select [View -> CPU -> Status] from the menu of the HEW, click on the [Platform] tabbed page of the [Status] window, and check the number of cycles for execution shown in ...
Oct 29, 2014 - Value is edited in [Watch] window; correct value isn't in register
When the value of a variable is edited in the [Watch] window, the value is set in the size of the variable, according to the specifications of the simulator debugger for the SuperH RISC engine family or RX family. Therefore, the intended value may not be input to the register ...
