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.

lens Supported, or equivalent functionality is supported | panorama_fish_eye Supported, but relatively inferior | — Unsupported | HEW High-performance Embedded Workshop
Notes
- CS+ allows specification of commands only before and after operations such as build, compile, and assemble.
- 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.
- 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.
