3. Executing simulation

If `--enable-sample' is set when ./configure is executed, sample simulators are installed accompanied with ISIS installation. For executing a program on an instruction level simulator, OSIRIS is needed to be installed with ISIS. OSIRIS is a tool for generating executable binary executed on ISIS. Refer the OSIRIS manual.
