The SimpleScalar Tool Set, Version 2.0, is a suite of free simulation tools designed for detailed and high-performance simulation of modern microprocessors. This report, authored by Doug Burger and Todd M. Austin, describes the release 2.0 of the tool set, which offers enhanced features, precompiled binaries, improved documentation, and better performance. The tool set includes five execution-driven processor simulators ranging from a fast functional simulator to a detailed, out-of-order issue, superscalar processor simulator. It supports both big-endian and little-endian executables and has been extensively tested on various platforms. The tool set is portable, requiring only the installation of GNU tools, and is easily extensible. The report provides detailed instructions on obtaining, installing, and using the tool set, including information on the SimpleScalar architecture, the target system, and the internal workings of the simulators. It also introduces two additional tools: a pipeline tracer and a source-level debugger (DLite!). The report concludes with a summary of the tool set's development history and future plans for extensions.The SimpleScalar Tool Set, Version 2.0, is a suite of free simulation tools designed for detailed and high-performance simulation of modern microprocessors.
