Running SPIM via Terminal While QTSPIM is very useful for debugging and visually understanding your code, sometimes you may want to run SPIM from a terminal window. To do this, you need to execute the command-line program spim . To start SPIM, run an assembler file, and exit (non-interactive mode), simply run the command spim -file ASSEMBLERFILE , where ASSEMBLERFILE is the name of the file to run. This is the way to provide command-line arguments to a SPIM program and run SPIM over an SSH connection. SPIM can also be run in interactive mode, which allows debugging and breakpoints. To start SPIM interactively, just enter spim at a terminal. Then, to load your assembler file, type load ASSEMBLERFILE . To run the program type run .
