SimpleScalar Extensions and Related Tools
This page contains links to the beginnings of our SimpleScalar user community "donated archive". This is where donated extensions, ports, and code that have not been incorporated into the current SS releases will reside. The maintainers of the tool set take no responsibility or assume no support for this code; if you have questions please contact the contact person listed after each item.  We've also included some associated tools on this page that don't strictly integrate with SimpleScalar, but still play nicely with it.

We would appreciate feedback about what you find useful, and of course always appreciate sharing of resources!

 
HotSpot Thermal Model HotSpot is an accurate and fast thermal model suitable for use in architectural studies. It is based on an equivalent circuit of thermal resistances and capacitances that correspond to microarchitecture blocks and essential aspects of the thermal package. The model has been validated using finite element simulation. HotSpot has a simple set of interfaces and hence can be integrated with most power-performance simulators like Wattch. The chief advantage of HotSpot is that it is compatible with the kinds of power/performance models used in the computer-architecture community, requiring no detailed design or synthesis description. HotSpot makes it possible to study thermal evolution over long periods of real, full-length applications.
SimPoint Analysis Toolkit A collection of tools to figure out where you should spend your time simulating to get fast, accurate, and representative results, implemented by Prof. Calder and his students at UCSD.  SimPoint can be used "straight out of the box" with SimpleScalar simulators.
