Compiler Survey NOW OPEN!
- 5 Winners to Receive Renesas Compiler License! - >> TAKE THE SURVEY (Open until June 30th.)

The CS+ (formerly CubeSuite+) integrated development environment provides simplicity, security, and ease of use in developing software through iterative cycles of editing, building, and debugging. You can use the basic software tools for developing software for Renesas MCUs immediately after the initial installation. CS+ is also compatible with Renesas hardware tools including the E2 and E1 on-chip debugging emulators (sold separately), which facilitates advanced debugging. Abundant extensions and functions for user support ensure a dependable environment for all users.
Compiler packages for the target products include CS+. Combining a compatible emulator product with either edition of CS+ (commercial or evaluation) makes all types of debugging functions available.

Important: CS+ is not generally promoted to U.S. and European customers.

Network Verification

[Debugging CAN bus reception procedures] No need for an actual other party when debugging communications

The inter-channel communications facility of the RS-CAN module is applied to facilitate early stages in the debugging of network communications without an actual other party. A desired CAN channel or reception of a desired type of frame can be debugged in this way. The RS-CAN module of the device must, of course, have at least two channels if this is to be used (Only for RH850 family devices).

  • Simply set the desired data and channel to make a program handle reception.
  • Not only single frames but sequences of frames in a specified order can be transmitted.
  • Creating test data is a smooth process since data for transmission can be imported and exported.

CAN Communication Time Measurement Solution

[Measuring times for CAN bus reception] This allows you to measure the response times for CAN bus transfer (up to the start of processing by the program after reception).

You can measure the CAN communications response times with the use of an E2 emulator, eliminating the need for an expensive CAN analyzer. This helps in the detection of problems at early stages (RH850 only).

  • Response times are important in CAN communications. This facility makes measuring response times easy.
  • A program can be made to stop when the response time is not within the allowable range.
  • After stopping the program, you can check the trace data or the history of CAN communications.

Learn more about CAN Communication Time Measurement Solution >>

CAN communication time measurement solution

Current Consumption Tuning Solution

[Measuring current drawn] You can check the relations between program operations and changes in current drawn by measuring system currents.

The E2 emulator allows you to measure system currents without using an ammeter. This helps to shorten the times taken in operations for the tuning of current drawn (only for CS+ for CC in projects for the RL78 Family and RX100 and RX200 Series).

  • Check the relations between system current and the operations of programs without having to modify your board or program.
  • Simply specify the condition and the program will stop when excessive current is detected.
  • You can also use monitoring points, in a similar manner to the setting of breakpoints, to monitor the relationship between the behavior of the program and values for current.

Use QE for Current Consumption to use these functions.

Current consumption tuning solution

Verification Through Fault Injection

[Pseudo-error debugging] Abnormal states which are hard to realize can be set up with this system.

States which would be hard to set up on the actual system can be created by injecting artificial faults (pseudo-errors). This allows the effective debugging of program actions in response to detecting the corresponding abnormal condition. This facility is only available on RH850 Family MCUs equipped with the Error Control Module (ECM).

  • Various pseudo-faults can be injected for MCUs, such as ECC errors and lock-step errors. Multiple pseudo-errors can be generated simultaneously.
  • You can easily set breakpoints at and after the location pointed to by the interrupt vector for the error, and use these to debug program operation in response to the error.
  • When various errors have occurred, you can check them in the [Pseudo-Error Debugging] panel.
Image
Verification through fault injection

Verification of Safety

[Exclusive control check tool] Check variables in access-prohibited areas to see that they have not been changed.

You can easily detect if variables have not been changed in specific areas (e.g., in an area where interrupts are allowed). You can also use this feature to check for the correct application of exclusive control.

  • Which functions access specified variables can be checked on a list of access (reading and writing). This is only for CS+ for CC.
  • Overwriting of variables in specific areas (the spaces taken up by specified functions) can be detected and indicated as errors. Such errors can be debugged by jumping from the overwritten address to the corresponding line of source code. This is only for RH850 devices. (Note1)

Note

  1. This will also require V1.04.00 of the CC-RH C compiler for the RH850 family.

Exclusive control check tool

Smart Reports

Collective output of quality-related information

You can use this feature for the collective output of quality-related information such as listings of source files, build option settings, information on functions and variables, and coverage rates. Note that this feature is only available in CS+ for CC. CS+ supports the output of information on various items, which is useful in verifying the security of user-created programs.

[Types of information that can be output]

  • Project trees, lists of dependencies, contents of the [Property] panel
  • Quality reports on building
  • Results of profiling of memory maps
  • Lists of functions and variables, analysis charts, call graphs, and tables of access to functions and variables
  • Build-tool information for compiler qualification service
Image
Collective output of quality-related information

Main-Core Debugging

Main-core debugging enables the development of user programs while keeping secure information confidential from engineers who are developing non-secure programs.

Specifically, this allows the debugging of user programs on the main CPU core with the user program for the ICU-M running but without the person using the debugger being aware of its operations or the contents of the secure range (only applicable to the RH850/F1KH and RH850/F1KM groups).

Other Aspects of Simplicity, Security, and Ease of Use

[Tutorials Make Things Easy]

Anyone can freely experience the CS+ IDE from the creation to the debugging of programs by going through the procedures given as tutorials.

Image
Tutorials Make Things Easy

[Easy Code Generation (Note1)]

The control programs (device driver programs) to control MCU peripheral features (timers, UARTs, A/D convertors, and so on) can be automatically generated from GUI settings.

The APIs for code generation have common specifications for every family of MCUs. Once you have used this code generation feature in developing a program, the only thing you will need to do when changing to another MCU with the same internal peripheral functionality is to replace the device drivers. This dramatically reduces person-hours for development. Hence, developers can concentrate on learning the new peripheral features instead of spending time repeating work that’s already been done.

The generated program code is in the C language. From the GUI, even a beginner on an MCU can see at a glance why a given setting is made or what procedure is being performed.

Note

  1. This feature is not supported for certain MCUs.
Image
Easy Code Generation

[Smooth Building]

In the conventional development environment, you had to execute all building after editing all of the source files. Building thus took a long time. The rapid building functionality of CS+, which automatically executes building from source files in the background every time they are modified or stored, dramatically reduces times taken for building.

Image
Smooth Building

[Smooth Debugging]

Furthermore, an “action event” feature is implemented for displaying the values of variables following execution of the program code at a given address.

The variable display feature can be specified by simply right-clicking on the mouse, so you can debug your code smoothly without spending time on extra build operations.

[Viewing and Finding]

The values of variables as the program is running can be displayed in an oscilloscope-like graphical form, so you can develop programs with an intuitive understanding of the analog changes which are essential to sensor applications and so on.

Also, identifying processes that impose heavy loads from the ratios of execution times of functions or from call graphs makes for efficient tuning of the performance of the system as a whole.

Analytical features such as sorted displays of functions or variables, output of CSV files, and the detection of definitions and declarations simplifies the management and maintenance of even relatively big and complex program structures.

[Backup Data]

The IDE has an efficient backup feature that can store and extract projects and tools in and from a file format.
