Using My Marie Simulation in TKGate

• Setting Up a program
  • Create a program in machine language
  • Your code must start at memory location 0
  • Create a memory file (the extension sould be .mem)
  • Instruction from the manual
    • blank lines and lines starting with a # are ignored
    • Format

      HA/w0 w1 ... wn
      	     

    • HA is an address in hex where the following words will be stored
    • w_i is a word in hex
    • w_i will be stored at HA+i
  • 
  • This is an example from page 176 of the book
  • This can be loaded into a memory directly using the Load Memory button
  • Or right clicking on the memory and selecting the load memory choice.
    • Click on the memory module
    • Click on the load memory button
    • Click on the memory file
  • Memory can also be dumped to a file.
• Setting up a configuration script
  • Using a configuration script, you can make it so the machine in in the proper configuration
  • Scripts end in .gss by default
  • There are many options detailed in the manual
  • The following work well
    • load g0.rammem "full path to memory file"
    • set Reset 1'b0
    • step 400
    • set Reset 1'b1
  • The first line loads your memory file into the ram
  • The second line sets the Reset switch to 0
  • The third lines steps 400 epochs
  • The third line sets the Reset switch to 1
  • The simulation is now ready to run
  • An example script
  • To load and run a script
    • Start the simulation
    • 
    • Press the execut script button
    • 
• I am sure that there are bugs in this machine. If you find one, please let me know.
