 ### Using the simulate script
-Alternatively, users can use the simulation script (`simulate.c`) provided [here](https://github.com/bucaps/marss-riscv/tree/master/scripts), which forks a child process. The child enters the simulation mode and execs the command. The parent process waits for the child to complete and then switches MARSS-RISCV back to emulation mode. With this script, it is possible to simulate any program without the need to modify and recompile the source code. Since the child switches to simulation mode before calling `exec()`, `exec()` also runs in the simulation. Hence, performance statistics generated at the end of the simulation will also include stats for `exec()`.

 ### Running benchmarks
 We have provided a detailed step-by-step comprehensive tutorial [here](https://marss-riscv-docs.readthedocs.io/en/latest/sections/running-full-system.html) to run the benchmarks on the simulator. This tutorial configures MARSS-RISCV to simulate a simple 5-stage 32-bit in-order RISC-V processor and run [CoreMark](https://github.com/eembc/coremark), an industry-standard benchmark that measures the performance of central processing units (CPU) and embedded microcontrollers (MCU).
