Renesas offers multiple integrated development environments (IDEs) to help support development. e² studio and CS+ (formerly CubeSuite+) are the most complete development environments we offer, and we offer several other special-purpose IDEs, including PM+ (Project Manager), and the High-performance Embedded Workshop (HEW). If you decide to change development environments, please use the following information to help you migrate your projects and/or code.

Please review the following precautions prior to changing IDEs, compilers, or debuggers.

Differences in Functionality and Operation

Functionality and Settings Summary PM+ HEW CS+ e² studio
Project management Batch management of files, settings, etc. lens lens lens lens
Changing the MCU Changing the MCU after project creation lens lens lens lens
Rapid Build Speeding up the build time — — lens lens
Customizing the build Specifying make rules applied when building a project — lens panorama_fish_eye (Note1) lens
Call Graph Displaying call Graph for functions — panorama_fish_eye lens lens
Function List Displaying lists of function addresses, references, etc. — — lens lens
Variable List Displaying lists of variable addresses, attributes, etc. — — lens lens
Detailed setting of events Event setting during debugging lens lens lens lens
Tracking event conditions Tracking event conditions after changing the source panorama_fish_eye panorama_fish_eye lens lens
Debug Sessions Managing multiple emulators or download settings — lens panorama_fish_eye (Note2) lens
Action events Displaying values and comments when running a specific portion of the code panorama_fish_eye (Note3) panorama_fish_eye (Note3) lens (Note3) panorama_fish_eye (Note3)
Settings Build options, debug settings panorama_fish_eye panorama_fish_eye lens lens
Pack function Saving and restoring tools used — — lens —
Updating Automatic version updating — lens lens lens
Command line Function for performing IDE operations by means of commands — lens lens lens

lens Supported, or equivalent functionality is supported | panorama_fish_eye Supported, but relatively inferior | — Unsupported | HEW High-performance Embedded Workshop

Notes

  1. CS+ allows specification of commands only before and after operations such as build, compile, and assemble.
  2. CS+ does not use the concept of sessions, instead allowing a single set of settings for each individual debugging tool. Multiple download file settings are therefore possible. Settings are entered in the properties of the debugging tool.
  3. Equivalent functionality is available by using printf in PM+, High-performance Embedded Workshop, and the e² studio (however, with PM+, this is only available on the simulator, and with the e² studio, this is only available on the virtual console). CS+ can output variables and comments without requiring code specifically for this.

Migrating Between Integrated Development Environments
