Running the simulation

Now you will exercise different Run functions from the toolbar.

1. Select the Run button on the Main window toolbar. This causes the simulation to run and then stop after 100 ns (the default simulation length).




(PROMPT: run) (MENU: Run > Run 100 ns)

2. Next change the run length to 500 on the Run Length selector and select the Run button again.
   

Now the simulation has run for a total of 600ns (the default 100ns plus the 500 you just asked for). The status bar at the bottom of the Main window displays this information.

3. The last command you executed (run 500) caused the simulation to advance for 500ns. You can also advance simulation to a specific time. Type:



run @ 3000 

This advances the simulation to time 3000ns. Note that the simulation actually ran for an additional 2400ns (3000 - 600).

4. Now select the Run All button from the Main window toolbar. This causes the simulator to run forever.




(PROMPT: run -all) (Main MENU: Run > Run -All)

5. Select the Break button to interrupt the run.

Your Source window won't look exactly like the illustration above because your simulation very likely stopped at a different point.
