Hi Eugen, The makefile in the UniFlex.OoO simulator lists the components compiled, forming the binary of the simulator. Having this information you can go into the "components" directory and check the .hpp files for any specific component you're interested in. You can then set new values for the parameters either in the wiring.cpp file (and recompile) or make your own configuration under "$FLEXUS_HOME/flexus-test-app/config". You can find more information on this here: https://sos.ece.cmu.edu/pipermail/simflex/2009-June/000505.html
I don't quite understand your second question. We are running Simics and Flexus on x86 Linux machines (called host machines). However, the simulated system can be either x86 or sparc. In your case, since you want an OoO simulated machine, you have to go with a sparc-based simulated system because our OoO codebase doesn't support x86 simulated machines. In any case you don't need to write any script. I hope I answered your questions. Let us know if you have any other questions.

I am looking for some quick hints about the Flexus toolset: My first tasks are to learn to use Flexus , and I am looking at doing small changes to an out-of-order pipeline ( changes in the branch predictor, execution units timing, cache sizes, delays , etc ) and see how that affects my performance for a simple set of benchmarks. I got the Flexus toolset built and running for the x86 architecture. I am learning my way around. Hopefully the following questions are very easy for anyone with a little Flexus experience. Now to proceed : - Where do I find the architectural parameters for the UniFlex.OoO architecture. Are these changeable in a configuration file or does it require recompiling the Flex "target" ? - Since I am looking at OoO issues I have to use the Sparc architecture. I am looking at full system simulations that run on Linux. I would need to change ( or create ) a v9.simics scripts that uses Linux instead of Solaris. Has anyone wrote such a script so I will not have to repeat the work ?
