PSIM is a program written in extended ANSI-C that implements an
-instruction level simulation of the PowerPC environment.
+instruction level simulation of the PowerPC environment. It is freely
+available in source code form under the terms of the GNU General
+Public License (version 3 or later).
The PowerPC Architecture is described as having three levels of
compliance:
VEA - Virtual Environment Architecture
OEA - Operating Environment Architecture
-PSIM implements all three levels of the PowerPC architecture and, in
-addition, includes (for each level) a corresponding simulated run-time
-environment.

+each level) a corresponding simulated run-time environment.

+In addition, PSIM, to the execution unit level, models the performance
+of most of the current PowerPC implementations (contributed by Michael
+Meissner). This detailed performance monitoring (unlike many other
+simulators) resulting in only a relatively marginal reduction in the
+simulators performance.
