Using the Graphical Simulator10.8. SIMULATOR SETUP10.8.1. Changing Simulation Speed and Session Date/TimeThe Graphical Simulator does not execute application logic in real time. Depending oncomputer speed, application size and other factors, one second of simulated time maybe more or less than one actual second of real time. For small applications the simulatormay cycle much faster than real time; an application that cycles once a second in realtime may cycle several times a second in simulation. This may be undesirable if itcauses events to occur faster than they can be tracked visually. One remedy is tocapture the variable changes in the History Window and examine them after they haveoccurred. Another is to slow down the simulator so that events occur more slowly in realtime. To change perceived simulator speed, go to Setup | Simulator Time in the mainmenu to open the Session Date and Time dialog.Figure 10–3. Session Date and Time DialogMove the Simulation Speed slider to the desired speed. If the simulator is cycling fasterthan the desired speed, extra idle periods are inserted to slow it down. Note that thiscan only change the maximum speed; if the simulator is already cycling slower than thedesired speed, it cannot be made to run faster. If simulation speed is set to its fastestposition, no idle periods occur and the simulator runs as fast as it possibly can.P2512A, Rev. Oct/09 10–10 Alstom Signaling Inc.
