Adding code

• Add the assembler code in the Simple-Assembler directory. Add the commands to execute the assembler in Simple-Assembler/run.
• Add the simulator code in the SimpleSimulator directory. Add the commands to execute the assembler in SimpleSimulator/run.
• Make sure that both the assembler and the simulator read from stdin.
• Make sure that both the assembler and the simulator write to stdout.

How to evaluate

• Go to the automatedTesting directory and execute the run file with appropiate options passed as arguments.
• Options available for automated testing:
  1. --verbose: Prints verbose output
  2. --no-asm: Does not evaluate the assembler
  3. --no-sim: Does not evaluate the simulator

Simple-Assembler

• The main Python file for the Simple-Assembler is called Main.py.
• Other than Main.py, we have also created three Python modules called InstructionDict.py, which stores a dictionary for all the instructions supported by the ISA; Registers.py, which stores the binary encoding of all the registers; BinaryConvert.py, which has a function which converts decimal to 8-bit binary, or returns an overflow error.
• The Shell file run inside the Simple-Assembler directory contains the relevant instruction to run Main.py.

SimpleSimulator

• The main Python file for the SimpleSimulator is called Main.py.
• Other than Main.py, we have also created one Python module called BinDec.py, which has three functions which convert
  • decimal to 8-bit binary or gives an overflow error
  • decimal to 16-bit binary or gives an overflow error
  • binary to decimal
• The Shell file run inside the SimpleSimulator directory contains the relevant instruction to run Main.py.

Question 3 (Bonus) has been attempted at the end of the Main.py file in the SimpleSimulator directory.
