2. Multiplexers and Demultiplexers

• Mux.hdl: Basic multiplexer (2-input).
• Mux16.hdl: 16-bit multiplexer.
• Mux4Way16.hdl: 4-way multiplexer for 16-bit inputs.
• Mux8Way16.hdl: 8-way multiplexer for 16-bit inputs.
• DMux.hdl: Basic demultiplexer.
• DMux4Way.hdl: 4-way demultiplexer.

• PC.hdl: Program Counter, which keeps track of the instruction address.

4. Control and Computation Components

• CPU.hdl: The central processing unit of the Hack computer, integrating the ALU, registers, and control logic.
• Memory.hdl: Combines RAM and other storage components to create the main memory.
• Computer.hdl: The top-level module of the Hack computer, integrating the CPU, memory, and input/output control.

5. Logic Gates

• And.hdl, Or.hdl, Xor.hdl, Not.hdl, Nand.hdl: Basic gates implemented using HDL.

How to Use

1. Install Hack Simulator: Use the tools provided in your repository, such as HardwareSimulator.bat or HardwareSimulator.sh, to test HDL files.
2. Run the HDL Programs:
   • Open the HardwareSimulator.
   • Load an HDL file (e.g., CPU.hdl).
   • Run tests using the provided .tst and .cmp files.

These HDL programs provide a complete implementation of the Hack computer and are perfect for learning computer architecture and hardware design principles.
