Running the Simulator

Step 1: Input Parameters

The  left-most panel of the simulator window has provision for taking various inputs from the user. The various input parameters could be set through drop-down menu.

We have provided four sample memory-reference trace files. There is also option for the user to input his own trace files through web reference. For example, to use your own trace-file "my-trace.txt", you have to first create that file and put it at a location that could be web accessible (e.g. http://your-web-location/my-trace.txt). The URL of the trace file has to be provided in the "Custom Trace Location" text field of the applet window.

Step 2: Press Initialize Button

Pressing Initialize button will trigger the simulator to read all the input parameters and memory reference traces. After initializing user has option of : 1) running the full simulation or 2) running till specified break-point (or events).

Step 3:

In this step user has the choice of  pressing Complete Run button or Run upto Break Point button.

• Pressing Complete Run Button: Pressing Complete Run button will trigger the simulator to run till all the memory      references has been exhausted. At the end of the simulation-run the output is displayed in the form of various statistics in the bottom panel of the simulator applet.
  
• Pressing Run upto Break Point Button: Pressing this button will trigger the simulator to read the memory references until the one of the selected event (e.g. TLB miss) occurs. Pressing this button again will start the execution from the last break-point. The memory reference at which a break-point event occurs is shown by cell in the memory reference table blinking with red color.

Step 4: Optional step to run the simulator again

To run the simulator again, first you have to press CLEAR button. Then you have to follow step 1 to 3 as listed above.
