SimOS
SimOS was a full system simulator, developed in the Stanford University in the late nineties in the research group of Mendel Rosenblum.[1] It was enabled to run IRIX 5.3 on MIPS, and Unix variants on Alpha. [2]

[edit] Derivatives
[edit] SimOS-PPC
SimOS-PPC was forked from the original SimOS as IBM's internal project, running a modified AIX kernel and userland in an emulator, developed by Tom Keller and his team in the Austin lab of IBM.[3] IBM used SimOS to facilitate development of new systems. The software used in this project is now publicly available for download for AIX 4.3 licensees.[4]
[edit] Linux/SimOS
Linux/SimOS was "...a Linux operating system port to SimOS, which is a complete machine simulator from Stanford. The motivation for Linux/SimOS is to alleviate the limitations of SimOS, which only supports proprietary operating systems."[5][6]
[edit] SimBCM
SimBCM is an open source full system simulator based on SimOS. It simulates BCM1250, a dual-core MIPS64 SOC of Broadcom. The entire source code of SimBCM is distributed under GPL.[7] It is capable of running the Linux kernel or the NICTA::Pistachio L4 microkernel.

[edit] Simics
The currently available commercial product, Virtutech Simics was derived from the work of the Swedish Institute of Computer Science, and was originally developed to run a full system simulation of Solaris on SPARC platform.[8] Simics was used by IBM to help develop AIX 6.1 on a simulation of the POWER6 hardware.[9][10]
[edit] RSIM
RSIM was the "Rice Simulator for ILP Multiprocessors", developed at the Rice University in the late 1990s. It was able to run on Solaris, IRIX and HP-UX. The simulator is available under the University of Illinois/NCSA open source license agreement. The development is finished.[11]
[edit] M5
Developed at the University of Michigan, M5 simulates Alpha and SPARC hardware, with support for other architectures in progress. [12]
