IAR Systems provides outstanding performance and feature enhancements for Renesas RX

Uppsala, Sweden—June 5, 2012—Today, IAR Systems® announces a new version of its high-performing development tool suite for Renesas RX microcontrollers. IAR Embedded Workbench® for RX version 2.40 brings highly improved optimizations and also introduces a new text editor and source browser.

Thanks to its best-in-class optimizations and user-friendly features, IAR Embedded Workbench has proven to be the tool suite of choice for many Renesas RX developers. This release further strengthens this offer by delivering even higher performance and ease-of-use. The IAR C/C++ Compiler™ for RX has been tuned to produce even better optimized code and the generated code is both smaller in size, and substantially faster in execution. Initial tests show more than 30 percent reduced execution times for industry standard test code, compared to the previous version. Added to the compiler is also support for the C++ feature Multiple inheritance.

The new version of IAR Embedded Workbench for RX also introduces a new text editor and source browser that adds a large amount of user-friendly functionality. New features include auto-completion, code folding, block selection, block indenting, bracket matching, and zooming. Character encoding support and word/paragraph navigation have also been improved compared to the previous version.

Another new feature in version 2.40 is a C-SPY® start/stop function available for the E1/E20 emulators. The start/stop function makes it possible to execute specified routines of the user application immediately before starting and immediately after halting program execution. Also added is the possibility to define custom SFR’s (special function registers) in C-SPY with selectable access size and type.

The version also adds new license features such as commuter licenses, automatic license activation and support for virtual servers, facilitating license management for global customers.

With more than 4000 supported devices, IAR Systems together with Renesas supplies exceptional design flexibility for embedded developers. The offer stems from a longstanding relationship, which enables IAR Systems tools to deliver outstanding performance for developers working with the extensive Renesas product portfolio.

Evaluation versions of IAR Embedded Workbench for RX version 2.40 are available at www.iar.com/ewrx.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
