Simulate Pulse Width Controller

Set the run-mode switch to down. Set the simulation run time to 500 . Run the simulation and observe the pulse output.

  • Make sure the run-mode switch is positioned down to run it in continuous mode.
    To make the simulation run continuously, flip the switch driving"Single-Step Simulation"down; when the switch is up, the simulation pauses after every clock cycle. Note each microcontroller instruction takes two cycles. The block named"PicoBlaze Instruction Display"shows which instruction is executing at the moment. Turning on the microcontroller's"Display Microcontroller Internals"checkbox causes internal values to be made visible.
  • Set Simulation -> simulation parameters to run for 500
  • Hit the Run button so the entire simulation is running.
    The simulation results of results1 scope will be seen as shown below

    Figure 19-3 simulation results of continuous run

    Channel 1 is the output pulse | Channel 2 is the port ID | Channel 3 is the read strobe | Channel 4 is the write strobe.
  • Change the pulse_width constant to 8 in the assembler code and re-compile the code using the perl script
  • Run the simulation and confirm the output pulse width has changed.
    If the switch is set in the continuous mode and the input-value is set to 0 then the design run continuously.

    How can the design be changed so that in continous mode you can specify the number of cycles it runs for can be changed?

    Use the STEP source and specify the amount of time the output is Low for

  • Implement this change in the design so you can run for 100 clock cycles
