This project is a full simulator of the WRAMP (Waikato RISC Architecture MicroProcessor) CPU used at the University of Waikato for teaching computer architecture concepts, along with the Basys board that contains the CPU.
Prior versions of this software simulated the Rex board which held an older version of the hardware, while this version simulates the reimplementation. It was updated in tandem with the creation of the reimplementation, so it should accurately reflect the behaviour of the hardware.
Running rexsim requires mono to be installed.
It has been tested under mono v4.2.1.0, with XBuild Engine Version 12.0.
Either double-clicking RexSimulatorGui/bin/Debug/RexSimulatorGui.exe or
running $ mono RexSimulatorGui.exe will launch the program.
On first open, two windows will appear: The main board, and the first serial
port. This serial port is used for communication with WRAMPmon. Type ? for
help, or simply run load to upload a program file. Dragging an .srec into
the serial port window will send it, even though the prompt tells you to press
CTRL-A S. Typing go after a file is loaded will run it.
The board's physical ports can be interacted with using the main window, and the tick boxes at the bottom of the window will open other useful windows.
To build rexsim on Linux,, xbuild should be used from the root directory.
From Windows, the project can be opened in Visual Studio.
